With the help of some experienced and respected members of the community (thanks!) there was formulated a rule that allows a third party code to be used under certain conditions. Please read carefully the text.
The following text will go as part of a renewed competition rules. The closest contest will be held already on the updated rules. Thus, there are about two days for further details, if something is unclear.
Solutions and test generators can only use source code completely written by you, with the following two exceptions:
- the code was written and published/distributed before the start of the round,
- the code is generated using tools that were written and published/distributed before the start of the round.
Any usage of third-party code should not violate the right holder’s license or copyright. Remember that published code is not always free to use! At the request of the right holder, any code that violates the license or copyright may be considered as violating the rules.
All the changes in the code from exceptions 1) and/or 2) must be made solely by you.
If there are any doubts about the time of publication, possible collaboration etc., a participant will have to prove his/her complete innocence by presenting compelling and satisfactory evidence.
Currently, the only reliable proof is the presence of code on the Internet and the presence of the used edition in the cache of well-known search engines.
For example, this rule accepts the use of the code from the website http://e-maxx.ru/ if the code was written and published/distributed before the start of the round. With the help of search engine caches, it can be easily shown that such code doesn't violate the rules. Similarly, it is permissible to use the code from a book/article that was published before the contest. On the other hand, using team reference code (for example, prepared for ACM-ICPC World Finals) is not allowed if there is no reliable and objective way to prove that the code was written before the contest.
This rule doesn't loosen the rules about prohibiting of communication, discussion, or any other form of communication between the contestants on any topics about the problems during the round.
Sorry if this is already answered in the text above, I'm not quite sure.
In a number of contest websites (including TopCoder and here on Codeforces), after a contest finishes, the source code for each submission is viewable by any member. Is this considered "published/distributed" code? (e.g. does this rule mean that all contestants can use past submissions of every other contestant?)
Same question for code snippets published on codeforces.com/blog/
Kindly review the logic used is same by everyone
Generally speaking, no, authors do not have obligation to release their code into public domain, they only provide unexclusive license for TopCoder

Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back
__Prophet___ Could you please explain what your issue was?
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody.
Same here bro , I also used ideone on default setting by mistake, what's the solution?
I tried running my code on ideone in default setting and someone copied my code and I was not aware about that.
Same happened with me.
same also happened with me.

I used Ideone as well and will never do this from next time.i did not knew it was default by public
I use ideone. I was not aware of this. Please don't block me or give penalty as I donot know about this.
I used Ideone as well and wasn't aware about the rules, I request you to not block me or give me any penalties. I apologize for my mistake.

same happened to me, wasn't aware, it was my 3rd contest, did not know about this. won't be repeated and i'll be mindful.
The same thing happened to me, I didn't knew about this things. Thanks for informing I will check this thing does not happen again. I am Sorry.

Sorry, it was my mistake that I use Ideone, actually I was not aware about the rules, please do not block my account.
same happened with me
Same also happened with me
please also me and do not block me
i dont know about idone.com
that happened to me twice before realizing that I was holding myself down by using Ideone in the first place
how much rating was deducted for this?
none but they rolled back my rating change and warned me that a third strike might get me panned
The same happened with me as well I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. Now onwards going to use sublime!
l
Same with me,I don't have idea that someone can see my solution on ide during contest, that's why i recieved a msg that your solution is colloide with others. I will take care from next time
Same happened with me, but I still got a "skipped".
Bro..what did you do after got a "skipped"? Same thing happened for me and I cannot register in upcoming Div2..please help me
same happened with me to i didn't know there were sites like these
Same thing happened to me in the contest. I usually code in sublime but on that day it was having issues, it was popping the Buy Sublime box again and again. So I decided to use ideone and forgot to switch the settings in a rush. This is the first time for me I had no idea about it, I will make sure it won't happen again. Please don't put any penalty this time, as it was unintentional.
Same happened with me, please give my ratings back.
I would highly recommend you take a look at everyone else's requests before posting you're own. IDEONE isn't affiliated with Codeforces. You won't get rating this round, keep that in mind for next round, and keep your ide's as private!
Same here, I used ideone.com so I done this mistake. Next time, I will take care. Please didn't reduce the rating. These ratings are very precious to me.
Same happened with me, I was using ideone for my few last contests, I did not knew that someone else can see my code from there, I am really sorry for this mistake. I will take care of this from next, please don't give me any penalties or block my account, I was unaware of this.
Thank you in advance!
same and i got skipped
i was also using online compiler.
same i too got skipped
Same, I apologize for this mistake. I'll be more careful in the future. I wasn't aware of the rule, so I hope you can avoid any penalties or blocking my account.
Same I also Got Skipped in a recent Div 2 Contest. I will take care of these mistakes I hope it doesn't give me a penalty or block.
Sorry but it was a coincidence. I was using ideone.com and wasn't aware that it is in public mode. Will never repeat this mistake. Sorry for that.

Same thing happened or me also
I didn't know code written on ideone was public by default. I'll be careful next time.
I did nothing wrong!
same thing
Same thing happened with me in the last contest. I wasn't aware that this was even possible!!
I had used Programiz to compile my code and run the test cases on the internet, since my vscode was giving issues. Please look into it, I didn't know the code could be retrieved from there.
The same thing also happened with me.They did not even change the author name!!
Its time to shift from ideone to sublime text XD
I have two acout,and this time I use the first acount to take part in the contest,but My cf tool is linked to the other acount, so i submitted the same code. What can I do now.
Realize that your lie is so terrible that you should take acting lessons
Having two accounts already violates codeforces rules
I forgot to disable public mode so sorry about that.
Same here

Same thing occured
Hey Same thing, I use to give my contest from my college lab as I live in hostel, and our college use shared lan on every linux machine which we use. We irrespective of our years sit in CP, but one thing for sure I don't cheat. Please don't penalise me for the sin I did'nt commit
Same thing happened to me
.
.
Same thing happened to me I guess I am sorry' though
I think I have made the same mistake and used Ideone in public mode without knowing someone can copy and refer to my code, I will take care of it next time and will either use it in private mode or shift to local. As a penalty you can retract my rating change for this contest, It will serve as a reminder of my mistake. I promise to make sure, this doesn't happen in the future
same
Same Thing
Sorry, but same thing happened. Writing on ideone on public mode was the cause. I would avoid using it from the next time
same.1994C submission of mine was in public mode.Also i have different approaches for the same question. Sorry for the unseen mode .
not only ideone,,, I got a mail surprisingly after yesterday's contest. I frequently used ideone, replit, coderpad, jdoodle yesterday and also these days. I never thought someone will hunt like this. Also I did a mistake that, whatever program I tested there was with a headline plus my macros with codeforces round name( I just tested from sublime to online IDEs). Just checked the mail and quick reveres engineered with the usernames given. Found telegram ids, channels with the same names. They provided the same solution(though they tried to change a little bit and maybe quick ChatGPTd). So it's a lesson plus warning for all whoever using ONLINE IDEs, please just don't use it without proper settings. And also sometimes, answer to some questions(specific), already available on the internet(the methods, solutions), it can also flag the submission as copied.
Same things happens to me
Same happened with me.i wasn't aware it was in public mode
same
Same thing happened to me too. I didn't have idea that even online ide's solution can be stolen. If this is the case, I will take care of it from next contest and will give contest from my personal IDE.
Please take it into consideration. @codeforces
As for rechecking, I am not clear. I have not referenced the code on any platform, nor have I submitted the code on any platform except CodeForces. Please restore my score.
someone cheated my code and he is skipped but I lost 200 scores, why ?????????????????? please give my scores back
it's so pity that this happened.I think it's a very coincidental thing, because this idea was brought up by my senior and me in class before. Please give my ratings back
I usually code on sublime but at Codeforces Round 963 (Div. 2). I didnt have my laptop so I used my sisters laptop to code on ideone.com since she didn't have the sublime setup on her computer. I had no clue about its public visibility. Please, give my ratings back this is not fair I worked hard for this and you guys are taking it away from me. That's not fair!!!
I am very sorry for the mistake I have made please return my ID it would be good for me
Same things happened to me.
I published my code on ideone.com & that's why the main reason it has been happened & please resolve that, in upcoming contest I wil not use these type of platforms.
same thing happened to me.
Do I understand it right? Presence in cache of well-known search engines is mandatory for a proof to be considered reliable, isn't it?
What about the Wayback Machine (archive.org)?
Is it reliable enough?
It is not polite
(and does not serve well to the community)
to downvote a comment without any useful reply.
As we can see, anonymity of the voting system encourages coward and irresponsible behaviour of the voters.
What exactly is cowardly about downvoting you?
Downvoting with explanation is supportive and responsible
(but yes, it is risky because your explanation comment can be downvoted itself).
Downvoting with no useful explanation is just harming another person's contribution score without taking any responsibility or risks for that.
That's why I call the latter behaviour coward and irresponsible.
Okay so this is just arguing for the sake of it, but...
Then why not to explain the reason of downvoting in a couple of words?
Otherwise, how an author (of a downvoted message) is expected to learn what exactly is "wrong, offensive or [inappropriate]" about his/her comments and why it is considered wrong?
(I think the practice of explained downvotes would significantly decrease the total number of "wrong, offensive or just plain garbage" comments because their authors had a chance to learn community rules faster: what is considered bad in this specific community, and why.)
I understand that there are obvious cases (such as offensive comments) where explanation is not needed. But in this specific case it was not obvious (and it is still not obvious). Not for me, at least.
I completely agree with you bro.
It's often the case that some very genuine comments get downvoted suprisingly. Even some contest announcements get so many downvotes. Do you think those announcements are wrong, offensive or just plain garbage?
Stackoverflow tried to solve this problem by removing 1 point from your reputation when you downvote something.
(A bit more detailed answer. Back to the original issue.)
A bad thing -- as I see it -- is that I was left alone with my downvoted comment and without important information.
Specifically, I still have no idea why the original comment was downvoted.
I do not have information, neither about what exactly was bad about that my comment, nor about who downvoted it (so that I could ask them personally).
How should I learn from my mistakes in such situation if I do not understand what exactly my mistake was?
In my opinion, sharing information which allows other members to learn is a crucial thing for a community.
I was also very confused by your comment downvotes, i undestand the way you fell, and really appreciatte the fact that you are not giving up and blaiming youself. People downvote maybe just to feel better and harm others, idk.I see many guys explaining their solution to problems that are not in editorial and require some advanced knowldge getting downvoted. That's the way things are, nothing to do about that. MAYBE I WILL GET DOWNVOTED TOO,tring to keep your side.
Hahahaaa XD
Solution to problem Codeforces round 447 Div.2 question A. QAQ was already available on the internet, well before the contest.Please visit source — http://www.geeksforgeeks.org/find-number-times-string-occurs-given-string/ to confirm. Hence I don't think people should be penalised if their code matches with someone...as they both referred the same source....codeforces please see into it !

Hello Everyone, This morning I got a message from system that my submission http://codeforces.net/contest/911/submission/33725640 during the Educational Codeforces Round 35, has been found significantly similar to http://codeforces.net/contest/911/submission/33725051 and my account my get blocked due to this.
Both of the submissions were made my me for Question C, and i was thinking that the earlier one would be ignored as we have in any normal Round.
I request the community to help me out here as I don't know whom should I contact about this.
For sure it is a technical mistake and it will be fixed today. Sorry about it.
...And Happy New Year!
Thanks a ton for everything sir :)
Dear Codeforces, @MikeMirzayanov I got one message that I got plagiarised solution for 1986E. I used a public website to write the program. At max that solution or that contest should be unrated for me but it should not decrease my rating by so much. Please take a look into it, I think there should be any problem in this. This rating is very important to me.
:(
I also made such stupid mistake. Sure, it is so awkward.
zhongyin is my other account.I wasn't aware of the rules. So I submitted same code in both accounts in Codeforces Round #459 (Div. 2) contest. I am really sorry for my actions.
zhongyin is my other account.I wasn't aware of the rules. So I submitted same code in both accounts in Codeforces Round #459 (Div. 2) contest. I am really sorry for my actions.
Please clarify the message that is sent to users. I don't know where to "write a comment to post about the round with all the details". If this is the right place, please re-evaluate my solution for contest 919. The system claims neutron-byte/34741180 is similar to czommerfelds/34745389. The solution is very simple so it is no surprise it would be similar. Also the first result on Google for "c++ sum of digits" yields the same function http://www.sanfoundry.com/cpp-program-display-sum-of-digits/. Thank you. Best, Christian
hello codeforces, i had a message after Educational Codeforces Round 37(Rated for Div. 2) .which says that Your solution 34846770 for the problem 920A significantly coincides with solutions oneplus3/34846646, codinghunter/34846770 .i want to say that both of the accounts(oneplus3 and codinghunter) were mine and i don't know the rules of submissions . But i promise that the soutions of both accounts is completely mine, and i won't make this mistake again.Don't block my accounts
"Attention!
Your solution 35396581 for the problem 939A significantly coincides with solutions Mushfikur_Rahman/35392093, RezaSi/35396581. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties."
i dont know him and not published my code any where :/ ... that's simple problem and may be many user have same solution for A problem in contest :/
I received a message from CodeForces after round# 464 that my solutions for A,B and D have been plagiarised. The solution to D was DSU and code was available on HackerEarth link for D's code. Problems A and B were trivial, I think because of similar template the solutions have been caught. The template which I use is really common. The codes for A and B were of <10 lines and hence the similarity. Kindly look into the matter.The variable names which I use are really common amongst the programmers hence the similarity.
Hi Mr.Mike! I'm Amir and today i passed the contest with my submissions but your system and your employees i don't know, said that i submit a copy code for my self. i have a question: If i have two different accounts and i want to participate in both of them, i can't do this?!?!
I'll thank you if answer my questions, rapidly! Thanks again!
Having more than one account is prohibited by the rules AFAIK.
i just wanna to ask if 2 accounts belong to 1 person and he did the contest with 2 accounts at the same time. Is it violation?
I dont know the rules of CF.And the other account is mine too.I submit my code on my account and i submit it with this account. Whatever,i am sorry for this thing happened.
Attention!
Your solution 36167133 for the problem 948A significantly coincides with solutions avyaktg98/36161438, kogorou/36167133. Such a coincidence is a clear rules violation.

This is a brute force solution and there was a similar problem "Palindromic Supersequence". Also if the members of the same team gets the same solution I recommend giving time to the involved participants to make changes in their code as the solutions are constructed while sitting in the same room. This type of instance is highly regretted and will be careful for the next time.
The solutions are not similar, they are completely the same. No one can believe in such coincidences.
Nice memes

That's because of Undefined Behaviour. You should erase by iterator, not by value (because in multiset you will delete all such values and iterator
itercan become invalid)Thank you for clarification

I used the official solution written in the Goodbye 2017 Editorial: https://www.dropbox.com/sh/i9cxj44tvv5pqvn/AAB1_2Q0XKvKiOA1ukvcNIuUa/F?dl=0&preview=F.cpp
Solutions and test generators can only use source code completely written by you, with the following two exceptions:
the code was written and published/distributed before the start of the round, the code is generated using tools that were written and published/distributed before the start of the round.
I used a code that was written and published / distributed before the start of the round.
The exact same thing happened with me !!
I copied Petr's code, I thought it would be better than the editorial anyway xD
This is my submission:
http://codeforces.net/contest/962/submission/37169973
This is Petr's submission on the problem from Goodbye 2017 round:
http://codeforces.net/contest/908/submission/33777962
This code was written before the start of the round. Apparently someone else copied the same code and I was charged with it being a violation?? I don't think that's fair.
I just saw that somebody else has written about our common problem, tell me if something changes for you.
Sorry, for being irresponsible. Yesterday in the "Educational Codeforces Round 42 (Rated for Div. 2)" I unintentionally used ideone as my system compiler wasn't working fine.I forgot to change the visiblity settings of ideone and someone intentionally misused my code. I would take care in future to not repeat this. my ideone code link during the contest is https://ideone.com/8vObjQ I saw the users profile with whom my code coincided(as said by you) ,his every solutions had been skipped which means he has a habit of copying. So i am innocent.

This is the problem I used as my source (and probably the others): http://codeforces.net/contest/908/problem/F 962E is just the same problem as 908F.
https://www.dropbox.com/sh/i9cxj44tvv5pqvn/AAB1_2Q0XKvKiOA1ukvcNIuUa/F?dl=0&preview=F.cpp And this is the source code
FOR EDUCATIONAL ROUND: 42 ( The latest one)
I received a mail about violating the rules of the contest, by copying the code. But I have conclusive evidence that I had taken the code from a AC code of another problem, 908F. If u want I can link the solution here, from which I took the code. However, it was present BEFORE this contest began. So I am not sure how this can be a violation of the rules. It's the setters fault that the problem was exactly the same.
My solution : http://codeforces.net/contest/962/submission/37168611 The code I took it from: http://codeforces.net/contest/908/submission/33800403
I too had a AC code to this problem:908F (http://codeforces.net/contest/908/submission/33824171) But that got some error, so I decided to take another code.
Please nullify the claim that I collaborated with someone else during the contest. It is pure coincidence that they took the same code.
great rules ...
Sorry, I don't know the code can't be discussed, this is the result I discussed with him.
My solution 38295464 for the problem 984D significantly coincides with solutions yqdjl4/38292975, xiaowuga/38295464. I think the idea of this problem is relatively simple, the code is short, the possibility of the code similar is very great, I see the idea of the code is almost the same, this question is I think independently, I hope to restore my ranking,
This question is not difficult, It doesn't need any algorithm. This problem needs to be preprocessed.I do not have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition.But I stayed up all night playing this game and seriously ponder every question. I don't want to be skipped this contest.please!!!!!

I dont know this guy.. maybe the solutions coincided.. requesting for a recheck.. and I didnt get any solutions from any source or other stuffs
Solutions are the same. By default some online IDE (like Ideone.com) publish codes. BTW I find it extremely weird or even dangerous. Be careful with them. Also prefer to use HTTPS in future and change passwords. Good luck.

i always prefer ideone for code ... and this is my code https://ideone.com/n0UjCL community please look at this and help me
Sorry I unintentionally used ideone.com for writing code and someone must have used it to see my solution. This won't happen later.
Hello, I recieved the following email from codeforces: Attention!
Your solution 40443772 for the problem 1006D significantly coincides with solutions vbbvaddd79506/40443608, Bogey24/40443772. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties.
Sorry for being irresponsible. In 'Codeforces Round #498 (Div. 3)', I used Ideone Online Compiler and forgot to change the default settings to private access. My ideone link during the contest is — https://ideone.com/BcjYgN. My code was used by someone else intentionally. I also saw the user's profile and observed that his submissions in past few contests have also been skipped. Maybe he had copied other user's solutions as well. Also I submitted my solution for the problem 1006D before this person. I am innocent and would take care in future not to use ideone during live contest.
As you pasted, "unintentional leakage is also a violation", so you aren't innocent according to the rules. Pay more attention next time and move on.
if me and my friend participated at the same time together consulting and solvong the problem together and due to that our code matches and this is our first time participating any contest so we didn't actually know the rules well. what can we do now?
Hi Codeforces, yesterday i participated on Codeforces Round #503 and I managed to solve 3 problems.
Unfortunately this morning when I woke up to check the results, i received a message from the system saying that this two submission 41488655 and 41489033 are the same.
I cannot deny that they look exactly alike. But when i did the third problem my IDE (CodeBlocks crushed) and i was forced to use ideone.com (link to ideone code, made 15 hours ago) to compile my code, and probably the other guy took it from there because I don't have any idea how else could he got my code. I didn't know that others can view your solution when using ideone. :( I will never use ideone again during a contest.
Now i don't have any idea how to prove myself as being the author of the problem. But i will try at least, maybe i can still keep my codeforces account. You can see for sure that the other guy copy pasted the problem. The first two problems do not match mine at all. And when you look at his submissions you can see a lot of them for problem C and the difference between last two 41488455 and 41488655 is just one minute and I don't see any way he could come with a totally different solution in just one minute. The submission are completely different.
And if i was using two accounts, do you think I would have wasted time coding two different solutions for the first two problems? Also you can see that the other guy, does this not for the first time, at the last Educational round he did the same. (image proving this).
I hope this can prove my point, have a nice day and thank you for reading, at least I shared my anger with you.
[Edit] Now it seems that i don't have access to any submissions. :(
As it is written in the message: unintentional leakage is also a violation. Please, be careful in the future.
I received a mail just now regarding the solution for problem 2014D significantly coincides with many other solutions! MikeMirzayanov Sir and Admins please look carefully as my code has been constructed completely in a different manner! Few part might be similar but I would like to put this clear Sir that neither I used any online complier nor I used GPT to search the solution for the problem, please recheck once so that you can also understand my point! I always adhere to codeforces rules while participating in the contest!

Hi, Yesteday in the contest "Educational Codeforces Round 49 (Rated for Div. 2)" I maneged to solve 3 questions out of 7 among which 1 was hacked. But suddenly today i got a message from your team that one of my solution match with some other user. Actually yesterday i used ideone with the privacy public by mistake. I think my solution might be leaked due to that problem. Sir/Madam, I am wrongly penalized as that was done unintentionally but i make you sure that mistake will not be done next time. Kindly look into this matter and remove my penalization for the same contest.
As it is written in the message: unintentional leakage is also a violation. Please, be careful in the future.
Hi today I have got this massage "Your solution 41863084 for the problem 1025B significantly coincides with solutions stormraider/41847161, travelers/41863084." We both have used same code from geeksforgeeks here. But I think it is not a problem but if it is I will be careful in future thank you. Also can you pls look into the situation and remove my penalty for the same contest thank you.

I got the message "Your solution 41863523 for the problem 1025F significantly coincides with solutions fateice/41858912, WAAutoMaton/41863523, zhang9302002/41864602, BLeavesCoder/41864866."
We used the same public code .It was published on 6/29/2016 and google cached the page no later than 8/7/2018. So I thought that it's allowed by "the code was written and published/distributed before the start of the round".
Please help me,thanks.
I have resieved the message that "Your solution 41864920 for the problem 1025F significantly coincides with solutions xzm2001/41862009, cubercsl/41864920." The problem is almost same to BZOJ4246 and we may use the same public solution and code. Please help me,thanks.Cache

I and my friend participated at the same time together and solving the problem together and due to that our code matches and we didn't actually know the rules well. I and my friend (http://codeforces.net/profile/DPO_WS) are very sorry about this, we won't do that anymore. Hope you can forgive us. Sorry if my English is bad.

I and my friend AzusaMiooo solving the problem together and due to that our code matches and we didn't know the rules well. I am very sorry about this. Hope you can forgive me.
I found the problem in the compilation environment three minutes before the competition, so I used ideone. I was not used to ideone, compiled without turning off the searchable option, and was excluded this round. I am aware of my mistake. Sorry. This may be insufficient evidence, but since most of my code so far has been written on the same template, I can show that the header, type definition, and variable declaration are exactly the same.
My source code of last round http://codeforces.net/contest/1025/submission/41833456 http://codeforces.net/contest/1023/submission/41750569

I will pay great attention to the use of ideone in the future. May I ask you for a favor in this round?
y creI created a different Id for myself to use .I am sorry that I used both IDs during contest .I didnt cheat nor copied code of someone else.
Hi,
This is regarding Round 511 Div 2. My submission, abhisheksince97/43197368 has been flagged for coinciding with solutions vbbvaddd79506/43196786, priyasen54/43197486, fibo1/43201480, gennadykorotkevichaz/43202067, cpp19/43202087, milanmas/43202887.
I can prove that the solution is mine and the others have copied it. You can open all my recent past submissions, I have used the same template for .cpp file as I have done in this one. The rest have clearly copied.
Also, the solution that I have written is available on geeksforgeeks (https://www.geeksforgeeks.org/largest-subsequence-gcd-greater-1/). This could also be the reason for the match.
I was really foolish and naive to have tested my code on ideone. Please verify that I am the true author of this solution and please let this contest be rated for me as I put a lot of effort into it. I have never done such a mistake before and wont do it ever again.
Hi, This is regarding solution 43335491 for the problem 1058D - Vasya and Triangle , I have solved this question on my own ......I also matched my solution with 43330317 yes we have same variables declared due to which this misunderstanding took place ....but as you can see there is a lot difference in my templates and him....which I always use. This is just a coincindence and I am Innocent. Kindly consider my submission and do not block my account Thank you.
Yesterday, the two IDs, huangzhengdoc and hz2016 were my IDs, because CodeForces could not be found in some places in China, so I chose a domestic agent, but when I submitted last night, my two accounts have been switching because The proxy IP is the same, I can't choose, so both accounts are submitted, but after the game, I sent an email to the contest author's email address [email protected], asking him to help me solve this problem and delete one of them. The account game, but until I have not responded, but I can only do this to solve this problem.
Sorry but my code is different with code of 18tin_nntan/45607672!!! I think my making is some same with this code may be because I and he have the same think!! Because this test is so short and the making is so easy to see!! So i thnks that is the reason why my code is same wiht 18tin_nntan/45607672. It is belong to maths!! And i use maths formula to resolve it!! I don't know him. I wish admin will review my code. Thanks you very much!!!
I didn't cheat.but I got out of the contest. It's unfair.
I got a message from system that my submission 46154222 during the Codeforces Round #524, has been found significantly similar to 46154175 and my submission get skipped.
Both of the submissions were made by me for Question C, and I have submit it to both my account.
I request the community to help me out here as I don't know whom should I contact about this.
Is it fine to take a piece of code from stack overflow or Github (e.g a sorting algorithm) ?
I'm new to this (obviously) : )
you can

i was using ideone in the public mode during the contest while solving B problem of Hello 2019 and i have not copied the solution and the only evidence about coincident clashing of solutions is that i was using public mode of ideone.
and moreover i was not aware of the rules
Sorry! I got the code from my friend.
First , I need to say sorry to codeforces . That submission'id is my another id.The two id both are mine,so we submit the same submission.That time I don't mean that was violation,I just think it's to do experimence. I ware of the importance of it,please give me a chance,I won't do that again.
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured
Sorry but it was a coincidence ..... I published my code on ideone.com that's why the problem has occured. Please give my ratings back
sorry,i used to do the similar problem on luogu.org.The other one is my classate,maybe we have many things in common,but i am sure we didn't communicate during the contest.
we usually learn on the same text book，it is obviously that we would have something in common，but we never cheat during the contest.
Sorry for the problem that occurred. I was unaware of the fact that ideone.com has settings like Public or private. Sorry if I degraded the tempo of the contest plz forgive me this time, I 'll ensure that same never happens in the future.This is the first tym I came across such a problem. I truly ensure u that in upcoming future it wont happen. Sorry

Hello, I received a message saying that my solution for Div2D of round #546 coincides with the code of other users. The code is clearly different and for a problem with such a short solution it is likely for the code to be similar. Please look into this.
Here is my submission which got flagged: https://codeforces.net/contest/1136/submission/51189268
Here are the other ones which were compared: https://codeforces.net/contest/1136/submission/51184411 https://codeforces.net/contest/1136/submission/51186289
https://codeforces.net/contest/1136/submission/51188835 My solution also got skipped i'm sure that no one took my code. The problem need 40~50 lines of code it's normal that to many codes are similar.
...
give back my ratings i din't copied i ran my code in ideone.com that was my mistake and also you can the see the way i wrote the code is completely different than the others.you can view my past submissions you will find it. the way of writing code is different i also wrote my initals firefox at top of each code my initialisation for every code is the same refer my previous submission
I used Ideone for the problem 1985G and wasn't aware about the rules and the public or private mode, I request you to not block me or give me any penalties. I apologize for my mistake. Kindly, give my ratings back.
Sorry.We shared our ideas in the contest.I promise i will not do it again.
I really hope for it.
Thank you for alerting me.I will remember this lesson.
Sorry, I don't know what is going on. Why is the code I write myself the same as others?
。
hello codeforces, i had a message after Codeforces Round #552 (Div. 3) .which says that Your solution 52860738 for the problem 1154C significantly coincides with solutions 2018030402024/52858419, 2018030402055/52860738.i want to say that both of the accounts were mine. i want to try my code on another account and i don't know the rules of submissions .

Actually me and Muhammad4hmed was solving problems together and he used my built logic actually we both are new and have no idea about the rules of codeforces. Kindly forgive us this time, we will be careful from next time.
Those submissions are character-to-character identical. Doesn't sound like "Actually me and Muhammad4hmed was solving problems together and he used my built logic".
bro we were sitting together and we solving in team
i don't know whether is this allowed or not
but it was the case.

I have got this message from the system of codeforces I would like to clear that shadyman123 is a friend of mine at my college. Thus it was during one of those post competition discussions that I showed him my code and he too began using the same macros. As for the logic of the code I don't think that he could have done it any differently he could have differed his solution with mine in terms of only power function. As an evidence you can check that I have been using those macros previously than him. I hereby request you to please do not punish us with penalties.
Your solution 55459961 for the problem 1182C significantly coincides with solutions Athena_1111/55457716, Anti-Mirzayanov/55458879, gandhipaaji/55458903, shreyanshgeek_unofficial/55458966, Harsh_jiit/55459119, turtle407/55459150, kaptaan/55459742, firefox/55459961, shivansh100/55460142, Izanagi/55460447.
you can view my other submissions and can found out the macros i use its the same .the way i code is the same.the logic might have coincided doesn't mean that i have cheated. please give back my ratings. And also you can check my other submission you will found out that i am not guilty.

How can you be such a liar? You copied my code literally. It's better to apologize rather than begging for something you don't deserve.

I just got this message. I want to clarify that I was using the online compiler ideone.com without knowing that apparently my code was public. I have not copied the code of anyone!! You can check the timing. I have written every line of this code. I haven’t even used functions form any websites. It really pains to receive this message in the first contest where I do well. What a luck!!!!!!! :/
Plus you can check the format of this solution with my other solutions. It’s the same.
Good evening.
I joined the last Codeforces Round(#566,div2) , but it turned out that "my solution 55459352 for the problem 1182E significantly coincides with solutions AH_ljq/55459352, wh_ZH/55461495".
wh_ZH is one of my classmates, you can see that we are in the same organization "ASDFZ". Before the Round finshed, I shared my methed with him. He got it, and finally he solved the problem as well.
I promise that I thought and solved this problem on my own. One reason is that my solution is ealier than his.
My submissions were skipped, and my rating drops a lot. Wish you can change the judgement of this round to me.
Best wishes.
I'm sorry for my fault at that round, and I won't do like that any more. Tanks for giving me a chance to correct it.

ideone shouldn't be used during participating in contests as your solutions may be shared with other participants so you may use ideone in private mode(not secret) or the best solution is to use an offline IDE(eg:- DevC++,CodeBlocks) or Codeforces IDE in custom innovation tab or use Geeks for geeks IDE

my submit isn't like yaman211 submit and i am who write this code and there are alot of similar code of my code and his code plus you can check the format of this solution with my other solutions. It’s the same.
i hope return my rate back..
And why you are remove my solution and leave me in the contest thats hurt my rate alot At least return the previous rate for me
I managed to reach this rate after 2 months of training Please help me
In the last div 2 contest, i had another browser opened and logged in condeforces with my another CF account which i rarely use to practice. At first I accidentally submitted a sloution from that account and then again submitted it from my original account. I have proof that both of them is my account. so please give my ratings back
AFAIK, having more than 1 account is prohibited
I'm sorry it was a coincidence.I was not aware and published my code on ideone.com. I respect the community and it would not be repeated next time.

What is this?? It was not a case of plagiarism as such a small snippet of code is likely to be same, it's just a mere coincidence and nothing else. Please undo this action.
Man, your code and code of dsheikh are actually the same. Just dont cheat next time
Man, it's just coincidence and nothing else.
The solutions are exactly the same, it cant be a coincidence
same everything except you change t to z
just don't cheat to get rating, you will regret it

Sorry ! I didn't know the rules about submitting same code from two different accounts.Both accounts ("shaTheshah" and "cycle") are mine. I won't repeat this in future. Thanks
Having multiple accounts is also against the rules iirc.
Hello Everyone, I got a message from system that my solution 56579375 for the problem 1189B, has been found significantly similar to someone else's solution and a warning that my account may get blocked due to this. I wrote a very basic solution for that problem which was a short cut method, and it may possibly match with someone else's because no particular algorithm was applied in it and I used basic c++ syntax. I request the community to help me out and make my solutions valid for the round 1189B.
sir i used ideone and the user copied my submission from ideone . i did it by mistake sorry for the mistake the person was unrated and had no experience he misused ideone :( .The person name is Anonymous_CF_Tester/57406704 i didnt even knew him punish him he submitted later then me thats also the proof for this take strict action against him
Hey the same thing happened to me :( And how can i proof ? :(

I got this message after the Global Round 4. I used IDEONE and I think someone stole my B problem. I tried to first submit in Java and got WA and then converted it into c++ and got AC. I didn't know that using IDEONE would cost me this much. Won't use IDEONE again. And of course sorry for this.
Same situation...

I received this message with regard to the contest Codeforces Round 575 (Div. 3) . In my defense, I tried my code at ideone for assessing the time boundations. I had absolutely no idea about it's public visibility and these rules of codeforces. I apologise for any of the rule violations I may have unintentionally caused. I assure you that such mistakes won't happen again. I apologise again for the inconveniences caused.

Sorry, I didn't knew that Ideone.com can view other's code. When I was doing the div3 contest, in problem D2, I wrote the DP code but It was not sure that code I written is performed rightly. So I just had ran the D1 code(got the AC) with Ideone.com and just compared the output with my D2 code. It was just all. Sorry, I Apologize for my unintended mistake.
ideone shouldn't be used during participating in contests as your solutions may be shared with other participants so you may use ideone in private mode(not secret) or the best solution is to use an offline IDE(eg:- DevC++,CodeBlocks) or Codeforces IDE in custom innovation tab or use Geeks for geeks IDE
Sorry but it was a coincidence. I published my code on ideone.com that's why the problem has occured. Please give my ratings back.
That’s not what a coincidence is.
I am really very sorry. I was just coding on the general coding platform of our college, as my laptop’s battery went down. Hence, the code became public and this copy, pasting of code happened. I assure the Codeforces team, that this type of mistake from my end won’t happen anytime again. I am really very very sorry. Please, don’t block my account.
I'm sorry. At the beginning of the educational code forces round 70 (rated for div.2), my network was no longer available, and I thought I couldn't take part in the competition. I got the question through my classmate's network. After I finished it, I submitted it to my classmate's account. Later, my network became available for unknown reasons. I forgot that I have already submitted it to my classmate's account and submitted it to my own account. I promise this will not happen again. If you must ban, please do not ban my classmate's account, ban mine, I will be responsible.

I am really sorry for using the default settings on ideone.
My submission which coincides with Pr0n4x's submission : http://codeforces.net/contest/1200/submission/58611222
My submission made 51m:14s before that submission: http://codeforces.net/contest/1200/submission/58595209
These two codes are almost similar, the difference being 4 lines were modified in the accepted solution.
My submission of the solution of a another problem which was made before this contest: http://codeforces.net/contest/1201/submission/58273364
The code #58611222 has similar template portion of this old submission #58273364. I have been using this template for quite a while now. I hope this prove that I was the original author of that code. I am really sorry for using the public settings of ideone. It won't happen again. Thanks a lot.

I really don't have any clue about how my submission was similar as the other person mentioned here. For this question I didn't need to pick any code for the solution from anywhere. So I don't have any proof in favor of myself . But I expect that I should not be penalised because of such a coincidence and I just hope that such coincidence never happens with me again.
Sorry, I Shared my code with my teammate in the contest, but he has passed this problem, maybe he Shared my code with others. It won't happen again
I apologizes to you for I'dont know your rules clearly. Actually both oldherd and froldH are my accouts. I'm sorry for using these two accouts to attend the round and waste your time. But would you mind to cancel my punishment? You can check my IP to confirm that both froldH and oldherd are my accounts. And that will never happen again.
Hello Everyone, This morning I got a message from system that my submission for 1207A shahayush457/59278266 and 1207B shahayush457/59284151 during the Contest, has been found significantly similar to someone else's solution and a warning that my account may get blocked due to this. I was not aware about ideone.com and I was using it since the day I joined codeforces and for the first time someone has copied my code from ideone. I assure that this will not be repeated. For evidence you may have a look at his solution where he has copied my whole template along with my name and college name written on it anonanon/59284289 . You can also look that both of my submissions were made well before him. So, I request the community to help me out and make my solutions valid for the Educational Codeforces round 71 Div.2.
Hello Codeforces, I got the below message from the system after yesterday's Educational Codeforces Round 72.

In this contest, I use the template from https://loj.ac/submission/27031, to solve the problem F. As it's submission time(2017-10-07) is notably earlier than the contest time(2019-09-06), I firmly believe it can be a conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition. Therefore, I appeal to valid my solutions for Educational Codeforces Round 72.
Thanks.
I see, it is fixed now. Thanks.
Thanks a million for your instant help ;)

I apologizes to you for I don't know your rules clearly.To be honest, both Piccadilly and HoldTight(For Practice purpose ,I have created this recently) are my accounts.I'm really sorry for using these two accounts to attend the contest(Trust me ,I have no intention to attend contest from both ID .I have accidentally submitted solution from my Piccadilly account (I am checking standing from Piccadilly account ,checking current standing of my friends).You can verify this fact by submission timing of both account.
I was not aware of the rules.I have gone through all rules and regulations once again.So consider my actions as foolish mistake and don't penalize me.This won't repeat in future and I will be careful from here on.
Hi Mike, I've received this message "Your solution 60556771 for the problem 1209C significantly coincides with solutions know_no_algo/60556320 and xDxD/60560299... etc" I was using ideone with the default settings as I wasn't familiar with it and I'm so sorry for that. I also was struggling with the problem as I also got multiple wrong answers in it. Therefore, that proves that I was trying to solve it.
Anyway, I'm sorry and I won't use ideone again (that was my first time) and I was hoping if you can resolve the issue if possible and get my contest points (even if the points for problem A if I can't get C's points) as I was really hoping to be a pupil this round.
Again I'm sorry for what I've done and won't happen again.
Thanks. Have a great day.

He(201831990439) and I are good friends.He's really much better than me，so I imitate his code style，and also ask for ideas during the match,only for the ideas,and no copy.I wrote this code according to his idea, but there was repetition. I'm very sorry.I can don't want the G1 score, but as long as the score of the remaining topics, please agree with my request. Thank you.
Asking for solutions during contest is a type of cheating and violates the rules.
When you register a codeforces round, you should read the terms of agreement.
Term 3 asks you to solve problems independently.
I accept the punishment. Thank you for reminding me that I will not violate the rules .
I got a message from system that my solution 61138460 for the problem 1230A significantly coincides with solutions nafiscode/61138460, tourist_plus_kan/61141927.
It was really a coincidence. I solved the problem by myself. I didn't take help from anyone. I didn't publish the code anywhere.

I am really sorry for the violation caused. To be honest I am a very noob programmer. And last time (Div 3) my contest was supposedly going good. But then when even after the submission and upon pressing the refresh button again and again to see if it turns red or green didn't work. I panicked. And told my friend to submit the same answer, sending the code over whatsapp if she gets the verdict or not. There were quite a few submissions already with a verdict in her account. But then Codeforces Notification popped up saying the delay time in the queue for submissions. By then the damage had been done.
I am extremely sorry for the violation of the rules. And take the entire blame on me for the thing happened here.
Is there some sort of requirement to make a public apology on this blog? It's kind of annoying that every three days this blog pops up with some sob story. I mean you aren't getting your rating or anything back, so what is the point of posting here.
Just move on, you made a mistake, don't do it again, all is forgiven.
Hi, I am new to this website also to cp. I recently participated in Round 594 div2 and I got a mail from admin that code which i submitted for problem 1248A matches with cerberus87/62978380 I was shocked as i didin't share code with anyone so i went to that submission of cerberus87 to check his code and code is exactly same, then after reading few comments on this page i got to know that my code was taken from ideone where I tested it.It was my mistake to keep option as public and test it on ideone. So i request admin not to ban my account and I promise that I'll not repeat this again.
Also , out of interest i just want to know how do other users steal code from ideone and how do they identify the problem.I also doubt that cerberus87 is a dummy account as it was just created before start of exam and user was not active after completetion of exam

Hello Everyone, Today I Recieved "Your solution 63311611 for the problem 1251A significantly coincides with solutions mindJuice/63309844, gabish01/63311611" for Educational Codeforces Round 75 (Rated for Div. 2). This is because both accounts are mine, Both have autofill login details, so I accidently logged in using my alt account(mindJuice) which also happened for previous contest codeforces round #595 in which i continued on my alt account and didn't use my main account. In tomorrow's contest Educational Codeforces Round 75 (Rated for Div. 2) I was logged into my alt account from previous days and I had submitted solution for problem 1251A until i realize i was not logged in to my main account as I always give my contests using my main account(gabish01) so i logged out and submitted 1251A solution again using my main account and continued on that account, which was a mistake. You can even see my alt account Last Submissions is only 1251A and no attempt after that and you can also check the Last Visit of my alt account. That's all i can say to prove my innocence as that's what happened. Sorry for Violation of Rules, it won't happen again.
Well, alt accounts aren't allowed, soooo...
yuzhechuan / 63481947 solution for contest:I dont know this happened but because of my ideone.com public. sorry i will see that this doesn't repeat again.
sorry，I have used two account

Good morning everybody.
In Codeforces Round #604 div1, my submission is skipped. But I didn't copy code. The submissions what are checked 66350141, 66352679. It not same even the mothod of inverse.This problem if you can infer /sigma_p{c(p-x,a)*c(p-y,b)*p} to x*c(a+b,b-x+y)+a*c(a+b-1, b-x+y-1). And the method is same as Chinese contest noi d2t2. And I can control it.And you can see Gromah D1 and gisp_zjz D2. And you can see it easy to look like.
Please admin MikeMirzayanov check it, thanks.
Hi!
The matched submissions are:
I see that they are completely equal, the main parts of solutions use the same variables, same flow of calculations, same type-cast tricks and so on.
Please, provide me the common source (exact link, not a generic description). I don't have an idea of what is
Gromah D1 and gisp_zjz D2. Give us the links. Codeforces provides you an easy way to share a submission link. Anyway, I don't think other solutions are so close as 66350141 and 66352679.As discussed in https://codeforces.net/blog/entry/71916#comments, #604 Div.1 E is a similar problem with the one in Chinese Contest WinterCamp 2007, you can find the problem description in https://www.luogu.com.cn/problem/P4249, and I used the solution code in https://www.luogu.com.cn/problemnew/solution/P4249, which was published in 2018.
I think I should not be unrated for #604.
The punishment will be reverted.
Thank you.

For CodeforcesRound604 Div1 E，it can be showed that this problem is quite similar to a problem in Chinese Contest WinterCamp 2007，the code can be easily searched by Baidu or Google. for example,the following blog posted the code in 2018 https://www.cnblogs.com/zhoushuyu/p/9146420.html
According to the rule about the Third Party code，i think i should not be unrated. Please investigate this matter，Greatly thanks.

really thanks
My friends and I were at the same place, we all entered the last Codeforces Round #605 but we were not talking during solving any problem. I solved the first question by myself and tried the other questions. I don't know that they copied my code, it's possible because all our screens are open, we were at the same place... But I guarantee that I solved the question by myself and didn't copied it from any other source, also didn't shared it with my friends. You can understand that I am the first and only person in our group that solved the first question, by looking at the time that I solved. I want my ratings back.
So were your previous records cleared?
I participated in the Codeforces Round # 608 (Div. 2) and in problem D, I think there are many solutions, but because I have just learned a new algorithm, I tried it in problem D. I think the problem of D I like the other song just a coincidence. I hope I can get ranked
I've received the message
" Your solution 67105563 for the problem 1266D significantly coincides with solutions code026/67105563, apoorv024/67108912 "
Apparently that person seems to have ripped off all codes of today's contest. I have in no way posted on any platform, nor do i know the person. Neither have I copied any algorithm from any platform. The message asked for evidence. I think , my previous attempt , which failed at test case 5 , and then i debugged it, is a clear evidence that I've written the code myself. I'm dropping this message because the message I received mentioned me to do so. Kindly look into it.
I just received a message from System admin : "Your solution 67108912 for the problem 1266D significantly coincides with solutions code026/67105563, apoorv024/67108912. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation"
I have not posted this solution anywhere and have it only on my local machine. It is purely a coincidence that the other guy had the same algorithm and implementation. It is a fairly small and simple solution so I don't that its really improbable to get similar solutions. Please add me back to the contest.
I see that the other guy's (@code026) submissions have been restored but mine are still in skipped state. I am in no position to provide any evidence that I haven't cheated. And if the other person has provided proof about it, then it should be considered for me as well, right ? I request you to please restore my submissions and update my ranking and ratings.
First, I don't know the author about 1278a, and I don't know where to see his code. My code is my own. Second, the question about 1278c is that I mistakenly copied my classmate's code after asking my classmate's ideas, and then resubmitted a code written by myself. I hope the organizer can forgive meFirst, I don't know the author about 1278a, and I don't know where to see his code. My code is my own.

As for the 1278c question, my classmate asked me the idea, and then he typed it again after he understood it. When he submitted it, he mistakenly copied my code. Later, he resubmitted a code he wrote himself. I hope the organizer can forgive me

I thought for myself and got the solution to the problem 1278D. Just use and "dsu" to optimize the brute force algorithm. But I was not familiar with and made a stupid mistake, so I shared the opinion to my friend. Before he answered me, I found the mistake, corrected it and submitted my solution. I was not aware that my friend hasn't completed his solution and he just corrected and sumbitted the solution I sent to him.
I don't know the rules and shared my solution freely. I promise I won't share my solutions with anyone in the future.
I have made a big mistake and i really feel ashamed of it. I promise it won't happen again. I want to apologize for violating the rules of the community and contest. Sorry for everything sir, please let me continue with my profile for participating here. Sorry.
I don’t know who is this guy kjnkjn and i'm sure that my solution 67730219 for the problem 1279B
is my code
Sir the code I have written is mine I have used ideone because geeks for geeks ide was not working so I don't know who the other people are but that was my own code
Respected sir MikeMirzayanov, padamprakash2502 is my another account and in the contest #611 i submitted the same solution for problem 1283c which you can verify by checking submission time of two which is less than a minute .i was genuinely not aware of the fact that we cannot submit same solution from two different accounts. This was unintentionally generic mistake for which i am really sorry . And as per the rules i admit my mistake and will not use the account my another account padamprakash2502 further . i will take care of all the rules from next time onwards. Again i am genuinely sorry. Kindly do the needful and please update my rating as i have been using this account for participating in contests.
I used another account to submit the solutions of 1283B and 1283A. I did not know this was against the rules and I am sorry, I will not repeat this in the future
Is there some requirement now to post your sob stories and/or deeply heartfelt apologies under this blog? I for one am sick of seeing this blog pop up every week with some "most esteemed sir MikeMirzayanov, i am so greatly sorry but i didnt know it was against the rules to ask soluton from frends during contest" shit.
NOBODY CARES about how sorry you are. This blog is for when you were actually unfairly disqualified (i.e. used code from a public source and the plagiarism detector picked it up).

I typed the code myself and submitted at 19:55 (IST) and got AC in the first attempt. The other person got AC at 20:47(IST). He took more attempts. His final solution is different from his previous solutions but his code is different and shorter than mine. I think either he wrote the solution on his own or he copied someone else's solution. It's not mine.
I checked my history and saw that I had public mode on on IDEONE. I apologise for that and will make sure that I switch to private mode if I use Ideone in future contests.
That's no problem if you got this warning once, if you did not send your codes to other people intentionally. Just be careful next time. You can use, for example, cpp.sh to compile and run your CPP code online. You won't forget to make your code private just because this service doesn't have this feature.

Hello. I have been using IDEone for generating my code files. I never bothered about the public access on IDEone as I have never had any issues so far with it. (which by all means I had no idea could be made use of in such a manner)
I am new to CF and this is my first such message. I wasn't aware about it.
I just viewed the code for 1288A submission and it does match 100% with mine. Same with 128B.
I dug my history and found the IDEone submissions I made.
https://ideone.com/pB6llK
for 128A (It shows created 1 hour before. I was checking some hack cases right after the contest ended)
https://ideone.com/8yl3AZ
for 128B
I will be careful from now onwards.

Hello sir! My cf handle is harit29gangwani and I got caught on plag check since it was me submitting codes on both accounts, harit29gangwani and harit29dec04 Actually I just remembered today that I had an old CF account and since both had a similar rating, I submitted from both accounts to see which one gets a higher rating I will not use the account "harit29dec04" from now on and won't ever repeat this again Thank you
Proof: They were submitted within 10-20 seconds of each other. I apologize to you for I don't know your rules clearly. Actually both harit29dec04 and harit29gangwani are my accounts. I'm sorry for using these two accounts to attend the round and waste your time. But would you please mind to cancel my punishment? You can check my IP to confirm that both harit29dec04 and harit29gangwani are my accounts and are the exact same solutions. And that will never happen again.
Thank you so much
Ffs, stop posting pointless comments. It would be great if admins could disable the comment section on this blog. As pointed out by -is-this-fft-, it is ridiculously irritating to have this pop up in recent actions because some people have zero clue how Codeforces works and think this blog is some magical way to contact Mike.
I'm very sorry sir I'm a school student and this was my 5th contest Please consider my solution for this round as they were both my accounts only, otherwise, how could they have the same email address, name, school and the same solution posted within seconds of each other. It will never happen again as I won't use my old account from now on
Yours sincerely
Judging by the email/PM that gets copied here sometimes, I think you are actually supposed to post your appeals in a public comment. So I think the comments can't be locked.
The problem is that apparently some people don't get that "you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition" does not mean "I am very sorry, I didn't know the rules and asked solutions from a friend".
Hadn't realised that's the proposed way of appeals. In that case it'd sure be nice to just have this post as an exception that doesn't ever show in "Recent Actions". Otherwise it's a bit like the entirety of Codeforces is subscribed to Customer Support.
Sorry actually I was using ideone and due to which this error might have occcured and I assure to take care on any such mishappening further on. This was purely due to some coincidence.
Hello sir. I have received a text that My solution coincide with another ID. I am really sorry that. It was my friend's ID. He asked me that how I have solved question A. So I send my code to him. As it was his first contest he didn't know about the copyright violation. Please forgive us. It was a mistake. And That will never repeat. MikeMirzayanov
。
Call me racist but most of the whining (I repeat, whining, not false alarm reports) are from those greys and greens and cyans, and guess what, they stay almost the same (both in rating and attitude) after all the time.
Maybe they stay that way because they only participate in your contests.
Maybe you stay your way because you have no better thing than whining at my round (even though I'm certain you don't give a f*ck of its actual content).
Also, read your own comment out loud and think of its literal validity before proceeding.
Hello, I'm sorry that I broke the rules. I have my own opinions on problem B, but it's not enough to solve it. So I asked my friend for help. I promise I won't have another chance. Please give me a chance
A-70053242 B-70062291 C-70073631
These are my own answers, all before the incident. After I finished, I used my computer to help my classmate submit（A-70074197 & B-70073981） (he couldn't connect to the server) and forgot to change to his account. I'm sorry. I hope you can revoke the violation record under my account. Thank you.
Seriously... this thing is popping up in recent actions every time a contest ends.
Can admins disable the comments feature for this page?
I mean, most thing posted here are all in the following format:
This is just not right, I mean, reading rules is the first thing, and not reading the rules does not mean we should take mercy, and this thing pops up every day.
I'm fed up of this, so if it's possible, just disable the comments.
upd it seems that some people really are doing something here (they have strong clues), in this case, just do not let this blog post pop up in recent actions.
My solution to the 1291b problem 70051751 is very consistent with that in annualring / 70051751. I'm curious. Isn't this person myself? Then I set myself up as an untrusted user, which makes me sad.
My solution to the 1291a problem 70042290 is very consistent with that in annualring / 70042290. I'm curious. Isn't this person myself? Then I set myself up as an untrusted user, which makes me sad.
Hello, sir. Ca1xukun is my other account, I submitted the same solution, I don't know I can't submit the same solution from two different accounts I'm really sorry that I made such a big mistake. Next time I'll follow all the rules. If you can, I hope to get your forgiveness.
hello codeforces, i had a message after Codeforces Round #617 (Div. 3) .which says that Your solution 70267322 for the problem 1296B significantly coincides with solutions Iron_man_3000love/70267322, RUDRO_BU_CSE/70289774. .i want to say that both of the accounts( Iron_man_3000love and RUDRO_BU_CSE ) were mine and i don't know the rules of submissions . But i promise that the solutions of both accounts is completely mine, and i won't make this mistake again.Don't block my accounts please..

Sorry to disturb, my solution 70674217 for the problem 1300D significantly coincides with solutions 70676934, this simple code is from a previous blog that has been published for months. The URL is https://blog.csdn.net/weixin_30559481/article/details/99069024. We may just happen to use this blog at the same time instead of copying each other, thanks.
How to view the code that wants to be the same with oneself, I am a little suspect is system misjudgment!
If you're given the email, there will be the id of your submission along with such of the supposed-plagiarizing submission.
To view a submission by ID, using the link:
https://codeforces.net/contest/[contestID]/submission/[submissionID].The
[contestID]should usually be the id included in the problem that you've been caught.UPD: There can be a hack if you're totally unsure about the contest id. At the text editor used to type a comment in Codeforces, add a submission hyperlink, type in the id and then press "Preview" below the editor. Click the hyperlink showed on the comment preview to proceed (as long as you don't click "post", no comment will be made).
confirm.
Please look the submission mentioned below: by CaEdta : 70240740 and by me : 70243563 this was a question in the previous contest. From there, you can observe that we have been using the same templates. Yes, we are friends studing in same college. The solution in which our code matched was just a five line solution and those five lines were quite obvious once you have thought the solution. So, please consider my solution since this was a mere coincidence which obviously was unlikely to happen if we had used different template.
Yes, I approve this. We didn't share anything during contest.
After the Educational Round 82 I recieved a message:

I have no idea about why my solution coincides with that solution. I don't know him and didn't publish my code to ideone.com...
I request the community to help me out here as I don't know whom should I contact about this.
Yes, our codes are totally different in
mainfunction.The only thing that our codes have in common is in
checkfunction, where our ways to do dynamic programming are very similar. I think it is just by chance.MikeMirzayanov don't make it unrated plz

Hello, when I solving the problem E of Div.2-620. I found the problem should use LCA algorithm. However, I don't have the LCA template in my current computer, So I search the LCA template from the internet.
Here is my used template hyperlink: https://www.codeleading.com/article/8225969543/;jsessionid=5E9F8D2A3A0E8C43BF245320925CF568
May be user XRDS-BJFU101 used the same existing template and cause the mistake.
Here are our submissions: Bert/71163200 XRDS-BJFU101/71165359

Hello,I just received this email. When I solving the problem E of Div.2-620. I found the problem is a easy problem.(just need LCA template).Then I used my LCA template,but my LCA template is from the internet. This is the address of LCA template.(before this contest) https://www.codeleading.com/article/8225969543/;jsessionid=5E9F8D2A3A0E8C43BF245320925CF568 Maybe Bert coincidentally used a similar board. Actually, we don't know each other.
I got a message saying that my solution for problem 1304E coincides with that of some other participants. I used the CP Algorithms implementation for LCA which you can find here: https://cp-algorithms.com/graph/lca.html. This was published before the start of Codeforces Round 620 (Div. 2) and so it does not count as a violation of the rules.
Although I added a few additional methods in my source code, a big chunk of my solution was for the LCA structure. So I guess that could've set off the response. I hope this clears things up.
If you need any more information, please let me know.

Hello Sir, I would like to bring your notice to the fact that some people are using multiple accounts for participating in contests and they hack their own solution to get points.
For Instance: https://codeforces.net/profile/rajankur this user has another account with URL as follows: https://codeforces.net/profile/CryBaby This is his secondary account and he used his primary account to hack his own solution which he submitted from his secondary account.
Hacked Solution- https://codeforces.net/contest/1312/submission/72825800 Same solution from different account- https://codeforces.net/contest/1312/submission/72845580
Just wanted to inform you about all these things going on and I hope that serious actions will be taken against such people (cheats)!
Thank You!
Have guts to come in public than making fake accounts like this. There is nothing wrong in exposing the truth. And what points you are talking about? Go and check history, I never participated in a contest with both the IDs to avoid penalty. I occasionally give contest with that ID ( crybaby ). And please if you are really so concerned about cheaters then please make your original ID first. And talking about today, you don't get points for hacking. There was a genuine mistake in my code so I hacked it.

Hello, sir, please review this news. About question B in this game, I think everyone is writing this way, right? Directly sort the array and output it in reverse order. Why do you say I cheat with two similar codes? I admit my experience of running a trumpet in the past, but I've made some changes. I'm in a fair game. Please check it! Thank you for your understanding.
I don't know how it is done. And I search for coincidence of the 'vanshkamdar' code with me , there is some delay of the code submission. I submit the code before 'vanshkamdar' code submission.

I am really sorry, but I surely think that this user has copied my code from ideone. I checked his profile and he is just a newcomer. I assure MikeMirzayanov that I'll definitely look into this issue next time. Please don't take my rating.
You didn't have any rating to begin with.
The "System" says that my submission and icecuber's submission to Round 628B's problem B are similar. They indeed are similar, BUT the solution to that problem is so simple in terms of code that I believe most of the people who solved B, solved it the same way : just insert array elements into a set and output the size of the set. OBVIOUSLY There is a high chance of coincidence. This is just stupid.

I'm sorry, I don't have any evidence. But I have to point out that this person is indeed my classmate.

Sorry for being irresponsible. I unintentionally used the ideone compiler for "Codeforces Global Round 7", problem A, because mine was not working that well. I did not know that it was visible by default. I will be more careful in future. my ideone code link which I used during the contest: https://ideone.com/UrrUSU . I checked that person's profile who used my code and seems like he did the same with other problems as his solutions are "skipped".

But sir this was unintentional. I used ideone and its settings were default i.e. public. So, I think user beerussama used my code that was leaked on ideone.
I will take care of the rules from next time and will not let any of my code leak during competition. Please forgive me and don't degrade my ratings this time.
i'm so sorry :(

We are roommates and are also members of the same team. We have always played codeforces as a training match. On that day, we did the same questions as before. Because the thinking of question D is the same, the code is similar. Sir,can i get my rating back? We really don't want our hard work skipped.Please!
Now that I have read the rules of the contest in detail, we will never do this in the same room again,please give my rating back...i will not do the same mistakes again..please please please
Respected concerned authorities of codeforces,
I have been mistakenly caught in plagiarism in contest https://codeforces.net/contest/1332/problem/B with ranabarasyana/74981409
I didn't use codeforces ide as it wasn't working perfectly at that time as load on site was quite high. That's why I used ide(ide.geeksforgeeks.org) to implement my code. I was not aware of this fact that this ide uses cache data. I didn't save my code on the ide but somehow someone got access of that code using cached memory of that ide. I looked into the userId(ranabarasyana) with whom my code matched and I found out that he is a new user. You can check my submission for problem A as well both codes have same style of coding. I have been wrongly caught in the plagiarism.
MikeMirzayanov I kindly request you to look into this situation.

Reply:
First of all I want to have a deep apologize about my fault, that leak was unintentional and I've never wanted to leak my code in anyway. I used ideone as compiler because of my compiler, because I'm using my new laptop, and it didn't perform well in compiling so I used ideone as the subtitutive. I've never shared my ideone code to anyone, i've also never thought that my ideone code was forked 3 times. The 3 users that copied my code i don't know who are them at all. I've looked at them all of them have lower rating or new guy in Codeforces. I don't code the problem in my account in ideone so i have not much evidence, and not set the code private. I would never repeat this thing again in future. (sorry for bad English)

;)
I solved the question on a local ide which is ide.codingblocks.com , hence making it public, it wasnt anything intentional and I am sorry about it. I make sure the mistake wont repeat. Thank you.

Hi , i just got an email from the system that a certain submission of my own on problem E2 on the current Div3 coincides with one also of my own submissions, i submitted the problem twice in the same time as my internet connection was poor, and all my solutions got skipped.. please help what should i do now ?
also, i didn't use ideone or any similar during the whole contest.
Hi I received a mail saying that my solution to 1335C significantly coincides with another of my own solutions. Actually, the first time I submitted, it got accepted, but I later noticed that there is a minor mistake in my solution (I started a for loop with Index 0 instead of with Index 1). So I corrected it and submitted again, and it was accepted again.
Dear MikeMirzayanov,
I have been caught in the anti-cheat checker in the last round, 1335.
The detail message follows:
As you can see, the coincidence came from the same account, which is the sole account I use for Codeforces. I have submitted the same code twice because the server 502-ed right after I sent in the first one, leading me to falsely believe that the code was not received by the judge. Thinking that the platform will warn me if I attempt to submit the same code again (it happened before), I submitted it again.
Therefore, I think that I should NOT be skipped from this contest.
emmm… I'm sorry to disturb you but I did have a problem.
Why do my three of code make me skipped？

The question was very easy and anyone can have the same idea for the question. I first submitted the code in java but was getting tle so i submitted in c++ and now this. I want you to please check this and don't cancel this round for me.
I interlaced the language, the first time I do not know that language, I am afraid that ce directly handed in the same, I handed in the code, I am not plagiarism ah!
sorry, for that at div 3 634# actually my first solution was in queue so i thought there is an error so, i again submit my answer that's why this problem occur please give my ratings back..i am really sorry for that.
You don't have to be sorry for that. Submitting multiple solutions for same question from same account isn't plagarism. There was some error in their plagarism checker. The problem will be resolved soon as it can be seen in notification now.
i didn't share my solution to anybody and i have got warn and disqualify why ?? i need help :D its not a good time to joke with me :D

First of all, I want to say that, gentlemen, I have not violated the rules of the competition. You can see the abcde1 code. Here is my idea of E2 question: it is to use prefix and record the number of occurrences of each number in each segment, and then you will enumerate 1-200. I opened a vector to store the position of each number, starting from the two ends, until the left end point is larger than the right end point and repeated operations many times, and then the initial value of ANS at the beginning is the most frequent one among all numbers. Although I don't know how many ways to solve the problem, the same method inevitably has high code similarity. Please believe my explanation and hope to give it back to me.

First of all, I am sorry to make trouble with Codeforces, and I looked at others submission which were metioned in the attention e-mail, actually it is so similar with mine that is possible for the anti-cheater system to think I cheated. But it is a coincidence absolutly. I solve all the problem by myself and I follow all the rules.

I'm very sorry that this kind of problem happened again in the codeforce competition. I have no contact with the person who checked the weight. I don't know who he is. I regret codeforce's duplicate checking mechanism. codeforce should be the place where we are happy with coding. we should not over-check the short question AB. However, I still want to pay tribute to you for providing a good platform.

Actually, we use the same template of segment Tree. The first time I saw the template was in exactly his previous solution 76170642.
This is the first time I have received such a warning and read this blog. But I am still wondering that can we copy the previous code of the contestants during contest. In other words, as the earlies post says,
Is this considered "published/distributed" code? (e.g. does this rule mean that all contestants can use past submissions of every other contestant?)Please forgive me for my poor english and sorry to bother nikolapesic2802.
I got the same message, and wanted to write a comment here asking the same thing. So i will just reply here. I'm ok with people using my template, but I don't want this to happen in a rated round. He even modified my template a bit. I wrote this template myself a few weeks ago. Can someone clear this up?
in last contest i mean codeforces round #637 i have been using ideone in public mode i think that is the reason someone has stole my code. it is not intentional if possible can i get my ratings back??

It was completely coincidence as I have used ideone.com also.It's same template I use on ideone.com.I don't know how this happened.pls give me my rating back. Extremely sorry for such a coincidence.
I will not repeat the same thing and will use different template as well.sincere apologies.

My ID is killerclaws_07,I got a message that my solution has been matched with some people, I didn't done in intentionally or not even send my codes to someone else. I was not not much familiar to not use ideone my compiler sometimes start to inerrupt so sometimes i use it.I started to learn Competitive Programming from Geeks for Geeks so i uses some of its concepts that i learned from GFG which is a public portal to learn, I have not used these portals while solving the problems but used the these prior aquired knowledge. I was not knowing about these things, from now onwards this mistake will not happen any contest, so, please do not reduce my ratings....
https://www.geeksforgeeks.org/find-subarray-with-given-sum/ this is link to reference of subarray sum which i described above
I think round #640 div.4 is unrated for me so i tried questions of it during contest but as i stuck on question E after getting MLE two times so i only take help to solve it in c++ as i have no experience in c++, so i google something and also take help from friend who is also unrated for this. But unfortunately code goes same so i get system mail. i know about rules during contest so i never discuss about questions during contest with anyone but because of this contest being unrated i take help in c++ code only. If same happen again from my side you can ban my ID. But for this time i have no idea that unrated can i have such a problem.Sorry for that this will not happen again.
MikeMirzayanov ,Sir I am really sorry for the miskate which I did in last round Div3( round#642). I already logged in my old account and I submitted 4 problems then suddenly I realized that this is not my current and permanent account then I resubmitted all the 4 previous problem + one more problem E in my current account not in old ones. Sir please look at this situation. Both are my own account and It didn't happen intentionally. please don't skip my solution all solutions are my own. I promise that it will not happen again in future.
Sorry but it was a mere coincidence . I tried to execute my code on ideone.com which is why the problem has occured. Please give my ratings back.

Mike you can check out that the editorial also got the same solution with just differnt variable. The following is editorial code.
include <bits/stdc++.h>
using namespace std;
int main() { int test; cin >> test;
for (int tt = 0; tt < test; tt++) { int h, w, a, b; cin >> h >> w >> a >> b;
if (h * a != w * b) { cout << "NO" << endl; continue; } vector<vector<int>> result(h, vector<int>(w, 0)); int shift = 0; for (shift = 1; shift < w; shift++) { if (shift * h % w == 0) { break; } } for (int i = 0, dx = 0; i < h; i++, dx += shift) { for (int j = 0; j < a; j++) { result[i][(j + dx) % w] = 1; } } cout << "YES" << endl; for (int i = 0; i < h; i++) { for (int j = 0; j < w; j++) { cout << result[i][j]; } cout << endl; }}
return 0; }
And many of us have coded with the same logic,just the varaibles and templates are different,u can go through the submission.So, please Mike help me with this one out.Thanks
Yes same happened with me .

I have used template code(includes Faster I/O and some useful functions) of aman28rwt which had been published before contest as solution on Codeforces.
Needed a clarification whether such usage of pre-written code is considered as violation of rules.
Just one suggestion avoid using Idione in public mode !

The problem seems to have arisen because both my submission https://codeforces.net/contest/1360/submission/81289637 and the other submission that has been flagged as similar https://codeforces.net/contest/1360/submission/81290251 use the same I/O template (Reader) that I got from GeeksForGeeks https://www.geeksforgeeks.org/fast-io-in-java-in-competitive-programming/ and it had nothing to do with the task at hand.
This is purely a coincidence and we don't know each other and have written our codes honestly and on our own. The main code itself has nothing in common but since the template is large, a lot of overlap seems to have occurred which has triggered a flag. I request you to look into this case, as I have been using this template for a while now but haven't faced such a problem before. Please advise what course of action i should follow in the future. Should I stop using a public template?
I got a plagiarism message from System for today's div 3 (Round 644) and my submissions were first skipped and later on marked as accepted. So I guess the issue is sorted out. Anyways I will still write an explanation here.
You can check that the main function is totally different across all submissions. What common is Fast IO template in python which is available here in pyrival "A Python Library for Competitive Programming". Even better you can also check my previous submissions you will find the same fast IO template (those should be enough to prove that the "the code was written and published/distributed before the start of the round,").

Yes i messaged to mike and he said sorry and fixed it.
Hope it will not happen next time .

During the contest I didn't use ideone.com or any other online testing platform. I tested all my codes locally. I also don't know and have no contact with the user tykkipeli so I didn't violate any rules. I agree that our codes are very similar however the solution to the 1360F - Spy-string is a simple bruteforce so it is probably a coincidence.
Anyway, should I react somehow to this message? Because I don't want my account to be blocked.
I also definitely do not have leaked my code and do not know rapast. His code looks very similar to mine, but that is 100% just a coincidence. Why would I cheat for the first time in a round that is not rated for me?
sorry this time i was coding and saving my code to github but unfortunately github repository had public access so the code got copied by someone. Next time this will never be repeated.
will fast io template result in plagiarism in today's contest?
I published my code on ideone.com that's why the problem has occurred. I was not aware of this.It will never happen again
thats old lie come up with something new
Sorry for the coincidence. My friend and I actually used the same logic for the problem, that's why problem may have occurred. But I will make sure that doesn't get repeated in the future.
i have same problem :(((((((( my classmate copied my code when my contest finished.
my classmate just copied my code :( and he skipped. so there is no problem im sorry about that Codeforces I assure you (code forces) that will not happen again. im sorry /:((((
Sorry if this is answered above, there's too much comments and I do not have time to read all of them.
Once I tried to skip me out of a contest by copying codes(to avoid negative delta, and I will not do this ever again), but when I copied the code from Account1(already submitted & got Accepted), then submit it onto Account2, it ended up that Account2 got skipped and Account1 only received a message. i.e, the one submitted later got skipped and the one submitted earlier did not get skipped.
does this happen to everyone at all times? or mine is a special case?
(because I think all of them should be skipped, since the author may have unintentionally published the code with minor mistakes onto ideone while debugging and the cheater quickly fixed the bug and submitted the code and the author solved it later, it would be even more unfair...)
MikeMirzayanov please answer this, thank you very much.
In yesterday's contest, I used Ideone.com for coding solutions for the problems of the ongoing contest. And today I received a mail, that says, My solution is plagiarised as it significantly matches someone else's solution as well.
I was in a hurry, so used Ideone publicly and unfortunately, someone copied it even though I made solution from the scratch without any help
i have two ID on Codeforces. Unfortunately, I have submitted solutions of a contest from both of my id and hence, I got an email regarding clash of solutions. What should i do to prevent both of my ids from being blocked??
just be careful in the future, codeforces won't block any of your account for cheating only once

I would like to bring it to your attention that ujjwalsingh30 and I study at the same programming institute and there we solved a similar problem. Maybe that is why the similar kind of approach struck to us but I can ensure you that there was no sharing of code. I am sorry if I violated any rules but there was no sharing of code involved.
Attention!
Your solution 83958507 for the problem 1367B significantly coincides with solutions akshat13400/83958507, Aakashgarg01/83973030. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

I wanted to bring it to your attention that there was no sharing of code involved. The question was a trivial one without any specific algorithm of knowledge involved maybe that is why the solution turned out to be similar. Please review and update my rating. Thanks

Aakashgarg01 and I have both been part of a similar question in a contest earlier maybe that is why our approach was similar. But there was no code sharing. Honestly this type of question is popular and I have done 3-4 questions related to this (calculating the frequency and applying a mathematical formula). So it was a mere coincidence that the codes were similar. Please update my rating. Thanks
sorry but it was coincidence. i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody.that's why the problem has occured. Please give my ratings back.i promise you to not happen this next time.

I used ideone.com to check the code i had written from scratch as my compiler was not working. I was not aware that the code could be copied by anyone from there or there was a public mode. I am really sorry and this mistake will not be repeated in the future. Please do not take any action for a mistake which was unintentional.
Hi! I participated in codeforces round #652 Div 2 organized on 23rd June 2020. My submission was found to match with the submission of some other participants as well. I dont know how that happened but I would like to present my proof of innocence. I submitted the answer in python as well as C++. Please verify that the logic, variable names and everything was same in the two codes. I don't have a clue how the same code happened to get in the hands of some other participant. My laptop was showing some error on declaring an array of size 2*10**6 so I used ideone once for compiling. I am disheartened that my hardwork has been discredited in such a way. Please do check and see if something can be done.
Sorry it's by mistake I used the online IDE and don't change it's setting. I am a newbie and just started coding trust meit was by mistake and i will assure you that this will never happen again . Please forgive my mistake
Thanks
This blog is just becoming a place for people to complain about their plagiarism and that they want their rating back
Sorry, i was using ideone with default settings. I regret this mistake and it'll not happen again
In regard to the message which I received on leaking the code from ideone , I would like to clarify that I was unaware of the public and private modes on Ideone and this will not happen again.

I have received this mail just now, and I am deeply sorry about this mistake.Actually both the accounts are mine and one was open in the normal window and the other in the incognito, so I was giving the contest in this account(the non serious account) and by mistake one solution I submitted through that account(original account) as well, first a wrong solution and then the correct one ,only after 5 minutes after submitting did I realise I had made a mistake,I had forgotten about plagarism striking because in essence I wasn't copying from anyone else, so it just did not cross my mind,I am deeply sorry for this mistake and such an instance will never be repeated.
Today, I got the message that my solution of E1 Codeforces Div Round3. 653 was matched with Whistler27 and Crime_master_gogo. Actually Whistler27 and Crime_master_gogo are my other accounts. I removed some functions. I didn't knew about that. I will remember it for the future. So kindly please look into the matter.

Please give my ratings back for AlphaCoder47
sorry, but i haven't share anyone my code intentionally, actually what happen i have completed my Ist problem code and wanted to upload two at a time but in "sublime text 3"(my IDE) it goes on infinite loop by mistake and my system gets slow, when i compile my ist code on online compiler "ideone.com" for final uplaod to codeforces, it become public bymistake.
Sorry for that, next time i use another online compiler in such situations. sorry for that, please give my rating back please.
Stop faking and admit that you cheated. Ideone's recent codes section is temporarily disabled for the last 5 days. No one can access your code through ideone. Better earn ratings on your own rather than copy pasting others's solution. People like you are degrading cp!
Sorry but it was just a coincidence I used ideone.com using default setting it wont happen in the future.

sometimes same templates (segtree,Mo) use more than one person .is it break the code of conduct .
.
You aren't allowed to have two accounts, man. Registering the the contest twice is illegal; it clearly says so on the rules that you click when registering. Don't cheat please.
Actually I think we can have many accounts as we want to practice in codeforces. But it is not allowed to take part in the contest and solving problems with many accounts because it is cheating and violating codeforces contest rules
Actually both Javed123 and amit445 are my account only and due to some mistakenly I have submitted my code in both account which match to my account only i.e the another one. If you want I can give you the screenshot of that as well for proof. so, please give me rating this time and it won't going to happen again next time. my primary account is amit445 only and now I will use only. so, please give me rating for this time
delete the javed123 account and give rating for my primary account amit445. If you want my proof of javed123 account I can give you.@MikeMirzayanov
let me give you proof i.e javed123 is my account only by replying from that ID so please delete this javed123 account and give proper rating to my amit445 account and delete this javed123 account.sorry for inconveinience. @MikeMirzayanov Please check this out
skip all solution of my javed123 account but don't skip solution of my amit445 account for this time and next time it won't happen again.
Dude, having two accounts is illegal. Don't ask mike to change the rules for you, you shouldn't have registered with an alt.
I got a message that my code coincides with another participant. But if you see the codes there are some common variable names. and as it was problem A so almost everyone had the same idea and same algorithm to solve it. I don't see any point for sending me this message and make this round unrated for me. Please give it a look and fix this.
I insist that such coincidences are not accidental. This is a typical cheating. The fact that you have already come across before only increases the mistrust of you.
Hey! this is a justification Post. Somehow my code matches someones code for B Question of this round. Anyhow it was a 10-15 line code. It came out to be almost same with the other guys code. I dont know how to prove in this particular situation that my code is not share or what . I just wanted to say that it is a shear coincidence . Thanks. Please look into the matter MikeMirzayanov And if someone can helo please help me out. MikeMirzayanov
see that "Online C++ Compiler." in your code? your code might be published on that compiler and is copied by someone else
I published my code on ideone.com with default settings as public. It was a coincidence. Please restore my ratings.
Ideone's recent code section is temporarily unavailable from the last month. Atleast verify your lies CHEATER.
My solution 87876357 for the problem 1383A significantly coincides with solutions beginend/87872573, xgcxgc/87876357. In fact,this problem is very simple.I think it’s normal for the code to be similar. Can the administrator confirm this?
Today i got a message from the system regarding my submission 88337173 being similar to 88366303. I have not cheated from anyone and you can even check my submission time, it's before this guy submitted. This guy asked for code from me and i gave him. I was not aware about the rule of third-party code due to which this happened. I apologise for this and i will make sure this won't happen again in any future contests. I am sorry.
In my all previous submissions I have write similar type of code. There may be case that someone has used my previous code and saved it and used it further in running contest. So please consider it and please don't make my submission wrong.. It was just a coincidence... I will try my best not to use any such thing so that my code get matched with anyone.. Please consider it
I usually solve questions on ideone cz it is fast and shows all type of error. And after reading all the comments I got to know that there is something called public, private on ideone. Sorry for being stupid from next time I will be more cautious about this.It will be great if you restore my rating back
Today my submissions were skipped and I found my brother copies my code while i write them n he submits my same code n today i realised as i received a message from System. I am extremely disappointed as i worked really hard on the problems. Please MikeMirzayanov if u could help me it would be great! Thanks!!

I believe it is a coincidence as I used topological sort for solving this and picked the code from gfg https://www.geeksforgeeks.org/topological-sorting/. I realised that I use the same template as the other guy and the combination of above might be the reason for such similarity
today i received a mail that my solution 89446672 for the problem 1391B significantly coinicides with solution 89449504. i want to clear that may be it was a coincidence or someone has copied my code from ideone.com cause i forgot to change my default setting. i will make sure to change it next time i give contest and since this has occurred first time with me i request you to consider it as a mistake and consider my solution this time, and dont deduct my rating.

I got the mail about the resemblance of my submission as I was using ideone and didn't knew about the rules before, now I will be aware of it.
and also my submission was first so it can be proved that the code was written by me
During contest My laptop (4gb ram) got freeze,while opening chrome, Sublime text & ms paint(for visualizing problem). So i googled online compiler and used codepad for writing code, that's why it happened.it was the first time i ever used some online compiler. i won't use any online compiler in future.it was an unusual mistake,sorry. i will be careful next time.
[submission:89945529][submission:89946825] Sorry my English is not vert good.But I want my rate back.This is my submission last night.You can even see the "///" when I am debugging. You can even see that "yhf_2015" come to code recently even tow matches.I do not know who is he and if you see the submission:89920639 that you can find lots of differences easily.Please return my rank.Thank you！The rank is very important for me this time.It is the standard to attempt to join in the icpc
same situation
I had to become a candidate master
This is what I received today. The problem was from educational round 93 (problem D). It was a simple DP problem and the code was very short. I checked various other submissions and the code was similar for all. For simple and short codes, special care should be taken while detecting plagiarism so that the innocent person is not penalized. Anyways I was participating out of the contest but this person got penalized just because of shrt code and late submission. This should be better taken care of.

Firstly sorry for this unintentionsl accident..Acty this is not my main account.I use this account for practice.. unfortunately i submit my solve from this account..but my msin account is k.ebrahimy . So i quickly switch to my main account.Then submit there and compete there. For this accident i am so sorry.perdon me and please say what can i do.
You can't really do anything — what's past is past. Face the consequences, learn the rules, and move on.
Hello Codeforces.I made my official account @k.ebrahimy almost 4 moths ago.I have another account @ayepsuckit which I made 2-3 weeks ago. I submitted it from both of the account because i didn't want to lose my ratings for wrong soluton.I am sorry for that.I can ensure you this will not happen again.I request you not to penalize my rating.
When you register for a contest, you agree to follow certain rules. One of those rules is that you can only participate with one account. It's good that you seem to understand this now but there is no reason your rating shouldn't be penalized. In fact, if it were up to me, your rating would have gotten a -100 delta. So be grateful that the Codeforces admins are rather lenient in their anti-cheating policy.
what does it mean third party code?
If any two person share a computer ?
???????
I would think it goes without saying that you cannot share your ideas during an individual contest. If you collaborate with another person during a contest that is cheating. Personally I think that those who are caught cheating should face much harsher penalties (like a -100 rating deduction), so you should be grateful the Codeforces admins disagree.
As for the situation where you live together, unless you are sharing a computer this makes no sense. You can compete in separate rooms, or even on opposite sides of the same room. It's not that hard to put measures in place to prevent cheating, whether accidental or intentional.
thank you already understand it qpwoeirut
sir, mn_nazrul is my another account . in tomorrow's contest I submitted same code for problem A.. i really really very sorry for that. next time I will be aware of this. this was like an accident...i promise that next time it will not happen.

I don't know this person and this account is so new that it seems to be made for that contest only.He has pasted my exact solution just before the contest ended.I don't know how it happened it seems like he was intentionally doing this to make me fall in this plagirism.
I have not used ideone.com.I am feared to say that this seems like my password was leaked somehow.I will change my password.I have done nothing and all of a sudden I saw this message.Please tell me mike if I can do somthing else other than changing my password to protect by account from these people.
you cheaters would end up on this hall of shame soon
ha ha maybe you are the one who did this. There is a big point to notice that if paraboy29 wanted to get rating he may have made some changes but he submitted the exact some solution, this is weird. what was his purpose afterall if he knew that he would be caught! The conclusion is simple paraboy29 is just playing with this guy.
There is very high chances that some people are doing these things to their enemies so that they are displayed on this website. https://cf-x-user.herokuapp.com/
I think they can also lock their solution and just copy paste their enemies code and submit it from other fake account.
It seems that now people are not doing these kinds of things just to cheat and get ratings but also take revenge by defaming them using x-user kind of sites.
cout <<"Hello World";
I received the message of been skipped of rated for Codeforces Round #666(Div.1)
I promise I had follow the rules, and didn't talk with others or copy other's code during the contest. I really don't konw how did that happen. I think the problem C is a simple DP,and the equation is just four line. I think I get the message might because my equation is just write in the same format with someone, please check again. please recount my rating if there isn't a rules violation. I could provide other evidence if you need. thanks for your responsible work.
It might be my first chance to upgrade rating in Div.1. I was so excited Last night because I could solve 3 problems in div.1, and it might be my new beginning in icpc and college life.But this morning I received this bad news, it's so terrible and it really blow my confidence a lot. I sincerely hope for your rigorous work to recount my rating. Thanks a lot again.
So, after Round #666 today, I received this from Codeforces:
"Attention!
Your solution 91395855 for the problem 1397C significantly coincides with solutions Kuzey/91362792, pedrosa/91395855. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation."
It turns out that I don't know the person who sent the code similar to mine and I never used Ideone nor anything like that. I see that the similarity between the codes does exist, but I simply used the same variable names that I always use and programmed the same way as I always do. Furthermore, I believe it is quite simple to see that, due to the simplicity of the problem, it is perfectly understandable that such coincidences happen.
What happened is purely the result of a coincidence. I have never shared my solutions, nor did I copy anyone's solutions. I perfectly understand the situation, but I hope this misunderstanding will be resolved.
Hi Codeforeces. First of all, I do appreciate your efforts in holding a sound and perfect contest.
But I'd never talk to this guy before that message from the system. Please resolve that mistake.
hi codforces, hi MikeMirzayanov this is my submission 91406053 this is the submission 91405601 which the system tell me that is significantly coincides with my submission. i want to solve this problem please.
say any thing please. two_two
I tried running my code on ideone in default setting and someone copied my code and I was not aware about that.
It's very interesting how the entire text of your comment shows up 4 other times in this page.

I would like to request the moderators to provide me rating as these both accounts are mine,I was unaware of the fact that this would turn out to be something illegal. I swear I havn't used any malpractice or cheated from someone, both of these solutions are truely mine. Also I would make sure that this won't happen ever again.
There is a rule against using multiple accounts in a contest. You agreed to the rules when you registered. So there's no reason the Codeforces admins would give your rating back. Whether you knew it or not, you cheated and you have to suffer the consequences.
At least you seem to have learned your lesson and your comment isn't blatantly ripped off from somebody else's.
Taifur & remon17 both accounts are mine,I was unaware of the fact that this would turn out to be something illegal. I swear I havn't used any malpractice or cheated from someone, both of these solutions are truely mine. Also I would make sure that this won't happen ever again.Please give my ratings back
wow you even copied the above excuse
His problem also same.So i just copied. You can chek my Handle name Taifur & remon17.You will find every code is same in my both accounts
Firstly, I hope you do understand how ironic it is that your appeal for an accusation of copying is directly copied from somebody else.
Second, there is a reason Codeforces shows you the rules before you register for a contest. It's so that you understand and follow them. Ignorance of the rules does not make you immune to them. Read the rules next time.
I will note that it's understandable that you didn't read the rules (I think I'm in the minority when it comes to that) but it's illogical to ask for your ratings back. You broke the rules and suffered the consequences. And in my opinion, the consequences should be much harsher. So just be grateful your rating wasn't penalized with a -100 delta.
I have used ideone.com in default settings to test my code since my text editor was stuck,wasn't aware it could lead to leakage of my code

I'm sorry, I'm in the habit of saving code to the cloud. Every match I'll push my solution to github when it has ended. But during the round 668, I pushed my code to github before the match ended in misstake, someone found it and copyed my code. I'm sorry for my misstake， I'll pay more attention.

Attention!
Your solution 92260161 for the problem 1407C significantly coincides with solutions heisenberg1410/92260161, Ayush_Sawlani/92267437. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).
I had my Ubuntu crashed so I was using Ideone because I was operating from windows,and I was using it from my logged in account,Ayush Sawlani is my ICPC teammate and we are college roommates so my ideone account was logged in his laptop as well from some time before,so I didn't know this would happen I am really sorry for this , you can see our other submissions which are totally different ,infact he has solved even the 4th question but I haven't which shows this was not any planned cheating but a mistake on my part ,I am sorry for this mistake.
I second heisenberg1410. I admit to copying his code. After thinking hard on the problem 1407C - Chocolate Bunny I got tempted to copy his code. I'm sorry for forgetting the ethics of competition. I request the codeforces community to not block my account. I have been working on it for years. I promise this won't happen next time. As heisenberg1410 mentioned that other submissions are different, this violation for which solely I'm responsible, wasn't preplanned.
About YuMing_mov/92271820, guguguyoo/92275105.
I'm really sorry, because I am in the habit of saving the code on the server of the school. Later, I asked @guguguyoo who wanted to skip this game and copied my code. I don't know that. This is the proof of my submission structure. The reason is:
Some time before AC, I was modulating the code, and the content was basically the same as solution 92271820. There are 92270307 and 92271149
I have submitted the final result before @guguguyoo passes this question.
Please give my ratings back.MikeMirzayanov i.e blyat
Sir I really have no idea how someone else can copy my code.. This was just because I used ideone in public mode yesterday.. From now on I won't use this so that such type of inconvenience will never happen.. Sorry sir, I m talking about code forces round 670...

https://codeforces.net/contest/1419/submission/93247714 In this, I have only printed the sorted input. There was proper name used for https://codeforces.net/contest/1419/problem/D1 The solution was this question was trivial and can be done in less than 5 lines after taking input .It was mere coincidence that my solution matched with varunsingh00712/93258725.I agree it was a similar logic but name were clearly different , I am sure many people just printed the sorted array like I did. example : https://codeforces.net/contest/1419/submission/93263832 https://codeforces.net/contest/1419/submission/93258725 Though this guy got wrong answer but look at the code ,it is similar too mine .Though I dont know these people but still this is happening due to direct solutions. I hope the codeforces will either make trival short solution questions and fix this mistake. Thank you for your time
**this is a coincidence. I was using idone in public setting. **
Cheating bhi karta h, aur idhar bolne m sharam bhi nhi ati, Sudhar ja bhai
Solution was of 5 lines ... What is the probability that some user will use same lines in one of 100s of contests and around 20000 users ... To be honest very much
These two accounts are our public accounts.Both codes are from the same person.I can tell you the passwords for both accounts if you need them. I am sorry that these two copies of the same code have caused you trouble.We guarantee that we will not submit the same code in the two accounts in the future.I hope the score of this account can be retained. Thanks.
I just received a message from System: Your solution 93688303 for the problem 1420C2 significantly coincides with solutions 93698667. I have no idea how this match happened. I have coded this myself and haven't shared it with anyone / anywhere online. Our solutions indeed match a lot, but it's mostly because variables we used (a, l, r) was defined in problem statement itself. The best evidence I can put for my defence is consistency in my coding style compared with other problems. For example I use lf instead of endl.
I received a message regarding matching of my code with some one else code. But I wrote it my own. I don't know how that happened but I will take care at my best that such thing will not happen again. I honestly practice coding. Pleas e consider my point. I have been writing such type of codes for my practice and in contest.. And from next time onward I will try to take unique variables so that it does not match with any one.
I used ideone.com to make the code. I dont have an account and generally do code like that.
It might have been copied from there. Please see to it

Firstly i feel really sorry for being so irresponsible . Actually my friend asked for the reference because he was unable to debug his code , he was actually confirming whether his approach was right or not (he actually had the same approach but can't solve the bug). Unaware of the third party code rule in a hurry in order to check the code he submitted the same code which got eventually got accepted. This mistake was unintentional from both the side . I request the community to understand the situation and avoid any kind of penalties. We genuinely feel really bad for the carelessness shown from our side. None of us had any kind of idea about the plagiarism rules and we feel really bad for not reading the instructions and the rules properly. I can assure u that I will take care of all the rules and will make sure that i don't do something careless in the future.

at coder library?
I think AtCoder library is the reason why we're facing these warnings. AtCoder library is published at least 3 weeks before contest (GitHub says so) , and is licensed by CC0 license. I don't know what is happening, but we're not cheating but just using same library which is legit. I can show more evidence if asked.
Hi. It seems it is a false-positive case. I'll revert the punishment.
But unfortunately, now many contestants began to insert endless sheets of unused code into the code, which makes it difficult to manually validate such cases and significantly increases my work. Most likely soon I will come up with rules against inserting a lot of unused extra code into the source code.
In my university I believe they moved to validating copying on the compiled code instead, as the method of only name changing and slight changes in code structure was mostly enough to fool the code copying detectors.
Hlo sir , unfortunately I got a notification that your code matches with different I'd ,sir it's my mistake that I used ideone.com unfortunately because my compiler not working correctly.and due to slow internet connection of my another user copy my code and just paste it in on the contest .. actually I am new here I don't know to use ideone.com sir please don't skipped my solution and give the ratings back.sorry for bad English
Sorry.I've used two accounts ("chyen89" and "Chyen") to participate the contest(1422).After I submitted my code on one account(94685113), I submitted the same code on another account(94685290).

I even don't know any of these guys.
If I wanted to cheat, I know how MOSS works.
You can see my last 100 submissions even, you will find "arr" "se" "ans" as regular identifiers.
You also want me to attach a screenshot of my browser, that I googled the same, or is it enough??
Please, don't waste my time:
The codes are the same. Also, you were watched multiple times before on cheating. Just stop to cheat. Or read the post and give me hard proofs that the code above was available in public before the contest.
Your solutions got skipped in two consecutive contests.
How can it be in two consecutive contests?
Look closely at the submission times.
The out-of-competition submission was sent at 2020-10-17 17:40:33, while your submission was sent at 2020-10-17 18:06:38. So this is definitely an instance of cheating (whether or not you copied from that exact person; you could've potentially copied from some other person who copied from that person).
Doesn't really make sense why someone would want to cheat (isn't winning without cheating much more satisfying?)
Well, you do have balls to post this, i have to admit.
Don't know from where you copied again that you become expert again in two contests with a jump of +333
Vovuh sent me. You can mention and ask him oof.
I was just warned that my solution coincides https://codeforces.net/contest/1428/submission/95770881 with https://codeforces.net/contest/1428/submission/95769769. I think it's because we both use benqs template. Please take a look at this MikeMirzayanov. Thanks.
Edit: I also sent my first three solutions to E 20 minutes before rqi and is basically the same as my AC except me fixing my overflow. Also, I probably didn't leak because I don't use ideone and why would a red copy me?
I also received this warning. I coded my solutions locally, so I don't think it's possible for you to have copied my code.
Our submissions are strangely similar, but there are enough subtle differences to prove that they are distinct.
Hello Everyone, This after the contest I got a message from the system that my submission https://codeforces.net/contest/1421/submission/95885037 during the Codeforces Round #676 (Div. 2), has been found significantly similar to https://codeforces.net/contest/1421/submission/95884674.
Both of the submissions were made by me for Question B, and I thought that the earlier one would be ignored and don't know about the rule, Please consider my issue.
I request the community to help me out here as I don't know whom should I contact about this.
Please do something about it MikeMirzayanov. It won't happen again.
What do you want Mike to do? You cheated and you were punished.
My code has been copied without my knowledge. I wrote the code on ideone.com and someone copied it from there. How can I get my ratings back?
If you put your code on the internet, and somebody copies it, it's still your fault. Therefore there is no reason for you to get your ratings back.
I used ideone.com during my contest.I am sorry,please give me my ratings back[problem:677 C]
If the code you wrote becomes freely available online during the contest it's still your fault. Because of this there's no reason you should get your rating back.
Hello,
Four days ago i participated at Codeforces Raif Round 1 (Div. 1 + Div. 2) and i got this message: "Your solution 95788785 for the problem 1428E significantly coincides with solutions CoolFromTheInternet/95788670, eudanip/95788785, logicful_coder/95788876, tecca/95788995, vecolig619/95789102, 1000iq3/95789438, jackryan/95789473, qazwsxq/95791830, aman_coder1/95792004, MrMoon/95792084, ma_da_fa_ka/95797663. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). "
So what happened... Since i am not very active anymore in competitive programming competitions, i don't have an IDE installed on my laptop and i'm on windows. Therefore, for the sake of confort, everytime i do participate in a contest i use the CS Academy workspace. Unfortunately, the CS Academy workspace seems to give a Compilation Error for problem E (here is the code https://ideone.com/qytL3w). Because i did not understand why and i was losing time, i quickly checked my code on Ideone. And guess what, it worked and i submitted it (so Cs academy C++ compiler is bugged). For problem F, i continued on Cs platform. After that, i got the message above regarding my disqualification. Apparently, there are some virgins out there hunting solutions on ideone. One of them even managed to submit the code before me.
I will try not to insist too much on this mather (since it's my fault and some contestants did use my code), but if someone out there reads this message and makes a little research on this matter, i would really appreciate it. By research i mean: * You can check that the code i shared does not work on Cs Academy workspace but does work on Ideone or Codeforces (so my story is true) * My coding style is the same for all submissions. This does not apply for the other contestants. They don't even use the same programming language (if that's a criteria).
I am sorry it had to come to this, but this is the truth and i can't change anything anymore. I hope the administration will understand. Have a nice day.
I have known eudanip for at least 5 years and I am confident to vouch for what he's saying in this comment. Technically, I also admit that it was a breach of the contest regulations, but I also want to point out that it certainly was just a one time slip rather than intentional misconduct. I can see that a lot of people got their submissions nullified, so I hope that the administration team can show understanding towards innocent mistakes like this.
Hi. I recently received a message that my solution in a contest was the same as another account But I own both accounts and I can prove it please check it @system
If you participate in a contest with two accounts then you're breaking the rules. Anybody who cared to glance at the agreement you make when you register would know this.
Respected sir, code.test101alpha is my temp account(which i recently made), and in contest CodeForces Round #677(Div. 3) i first solved on my temp account and then after successful submission i submitted exact same code on original account(hardik7e) , and i was not aware of the fact that we cannot submit same solution from two different accounts. this was unintentional ...i feel really really sorry for such a big mistake from my side.i will take care of all the rules from next time on-wards. please forgive me this time. update my rating on my original account. Regards
At least you're aware of the rules now. But you probably won't get your rating updated since you did still cheat.

The rules state you can't use multiple accounts in a contest. Since you broke the rules your submission was skipped and you were punished. There's no reason you should get your rating back.
I actually shared the code with my friend.
So? You know that's cheating, right? What do you expect to happen after commenting this?
I didnt mean to offend you. I understand that what I did was wrong. And I assure you that, such a thing wont happen again.
It's fine, I'm not offended. Just a bit confused as to what you expect to come out of that original comment.

Mine and my friend code got matched (for the problem 1433B) but i already submitted my code beforehand and asked for his submission in between to get an idea of my error as we study together and share all our resources. This is my first contest and I'm new to all this, I accidently resubmitted his original code instead of mine with changes which lead to this. I hope you pardon me this time and give my rating.
Collaborating with others during a contest is cheating and so there's no reason for you to be pardoned. Unfortunately if CF does pardon people for their first contest then people will abuse this by creating even more alt accounts and trying to do very well in the first contest by cheating.
I suppose there's not much you can do except read the rules more carefully and then prepare for next contest. Having a study partner is a good idea, just don't collaborate during contests.

I use ideone.com for coding and had no idea that the code I write there was public. I will not repeat this. Please donot penalize me.
Any exceptions to rules will just be abused and so you're probably not going to get rating back.
Also, not really related but I think I_Love_Tourist_ is that insert swearword here that keeps cheating on virtual contests to get first place. I suppose I shouldn't be surprised that he cheats in real contests too.
I have not published my code on any site I simply solved it on codechef's compiler and copy paste to submit it. If any type of similarities are seen. It is total coincidence. You are requested not to take any action.
I recently created a new account for the div.3 contest. It seems that there is a problem using two accounts together in this contest. I'm sorry about my mistake. I won't make this mistake again. If possible, please restore my rating changes. It doesn't matter if the rating goes up or down. Once again, I apologize for my mistake.
Dear mannagers: I got an attention at Codeforces Round #680 (Div. 1, based on Moscow Team Olympiad)，my code is https://codeforces.net/contest/1444/submission/97349986 but the copied version was https://codeforces.net/contest/1444/submission/97319222 after my submission, I don't know why this happened, maybe my password was revealed.

I really don't know why this was caused, how could I prove I did not cheat? I did Kotlin in an online IDE, which must have caused the problem. But really don't know what to say, my submission was sent earlier, could that be a proof that I_Love_Tourist_ is the one that violated the rules?
At least if I were to cheat, wouldn't I do it in a rated round, not the Kotlin one? MikeMirzayanov Please take this into consideration before labeling me as a cheater in the final standings.
The same thing happened to me also in 1431A. I was using Kotlin for the first time, so didn't have any IDE set for Kotlin as I only code in C/C++.So I used Ideone.com for checking if my solution works or not and forgot to make the solution private which caused the solution to be public.
And I_Love_Tourist_ is the one who cheated from there as he submitted the solution after 6 minutes of my Submission and also it can be seen that he also copied the solution of 1431B from ScrappyDoo
I apologize for not making sure that my solution is not public and will not repeat this.

Sorry Sir, in the kotlin contest I only submitted code about problem A and B, which were given by my friend. He didn't participate in this contest. I really don't know where he got this code, and at that time We were playing a joke. In fact I know nothing about kotlin. I apologize for not making sure that my solution is not public and will not violate rules any more.
I asked him and he said he used Java to write Kotlin and it has a great possibility to coincide with others. Maybe it's just a coincident. I feel really sorry for that.

ohk man
Okay, so you have participated in over 43 contests and you didn't know about plagiarism check. That means, previously too you and your friend might have given contest together and had the same solutions, but because of some modifications, you didn't get skipped.

Hello Everyone, Today I had got a message stating that for codeforces global round 12 mysolution:https://codeforces.net/contest/1450/submission/100548053 is same as some other solution:https://codeforces.net/contest/1450/submission/100547349 I want to show that its completely coincidence and you can see both solution were not exactly same,Getting same logic by few people is common thing. I don't understand why I got penalities, I didn't violate any rule by sharing code with anyone or public shared sources. If someone could brief how does it work would be great help, so I could be careful in future.
lol , both codes are exactly same .its not a coincidence
.
I do not understand why my answer is the same as those of those people, I do not know anything about them, is it a data tracking error ???
leafy2001 and parmarshashank11 belong to the same person. I submitted my code from two ids just for fun and see how time delay leads to rating drops. My intention was not to cheat. It is my first contest, I will take care in the future.
BOTH ACCOUNTS BELONG TO THE SAME PERSON : SHASHANK PARMAR
Sorry but it eas coincidence. I have done a similar kind of question in geeks for geeks so I used that code as it here and I had no intentions of cheating. I got the logic of the code correct and didn't use any unwanted means in the code
.
Fixed, thanks!
1462B required taking input and using some if conditions to print the output, the same if conditions were written by everyone and even mentioned in the editorial. Writing the code in python even meant that indentation would be same for different people. It is just a coincidence that our codes matched. MikeMirzayanov please look into this.
Hey i just got a message that my solution sqqq23/101324061
resembles closely to solution of robert.chinem/101294568
div3 d solution , However i dont get it of course our logic is same but variables used are clearly different and implementation too is somewhat different also if you think a lott of commented code in my solution 'sqqq23/101324061' makes it suspicious then that commented code is from my unsuccessful attempt at problem C 'sqqq23/101302773' which i just commented.
I dont get why i am out of competition but roberts' submission have been accepted .Is it because he made correct submission earlier than me . If that's the case are u implying that i somehow got access to robert's code and submitted that because i cant think of way i could have done that . Please look in the case because i have clearly not cheated . Also if u think use of generic variables like 't' for testcase and v for vector and i for loop variables is somehow not safe to use and plz mention it.

I am sorry about my unawareness using ideone.com with the public setting. The reason I was using it because my local compiler couldn't compile my code while I was in a hurry and it happened many times before which I need to wait minutes so the compiler can compile again.
I will make sure it won't happen again, thank you.

I got the above message and I was completely shocked seeing this message as I don't know why this is coming to me. There were many users giving this round and I don't think so that our code is same. I have also seen other user's comment they also have the doubt in this question only. I don't think that this was the fair decision of not giving the contest rating. If someone have the habits of using the common variables then this may not be the sign of plagiarism as many of them uses the same. So its a humble request to look into my code again and give the contests rating according to it. I had given contests but this do not happened to me yet. As I was giving the contest honestly I had also submitted the E1 code after the contest ends and this can be the prove because if I want to copy the code then why I will do it after the contest ends. So sometimes coincidence might happen that some other user also uses the same variable or logic as the question demands that. So Please have a check and give me this contest ratings accordingly. As we just use our precious time to practice the codes and solve the contests to increase our skills.
I regret to inform you that your application has been rejected. Your solutions are exactly the same, there is no reason to believe that such a match is expected. As it was written in the instructions, you were supposed to provide evidence, but they were not provided.

Round 690 Div 3 Problem D Please notice that the reason for similar solutions is because of using a helper function KpartitionsPossible which was given by Geek for Geeks as reference way before the contest. Here is the proof: Proof The following is my submission: My submission Please check that I only have used this function as reference. Any mistake here is unintentional. I am sorry for the trouble caused and I guarantee that this wont be repeated in the future. It is an earnest request to you to give me back my ratings as I had worked really hard for this contest.

Hello every one i solve my three problems correctly and accepted in first submit but next i got this message from system(codeforces).I understand that my and pam765 submission is same but it is totally coincidence. So this coincidence is formed due to the simplicity of this problem, even other persons are also used the same method to solve this problem(last year substring) from codeforces round #690 div.3. I also not used ideone to edit my code. please help me to come out from this situation. If any body wants more information about my problem please ask me in comment.. I also attached my submission history as a image.

Here is a link to my submission submission. I made the submission during Codeforces Round #690 (div 3) which was on 15 December 2020. I used the code provided in an article from Geeksforgeeks. This article was last updated on 09-05-2020, well before the contest. Hence this falls under code that "was written and published/distributed before the start of the round". The user Pam765 makes use of the same code from the article.
Fixed. In such cases, I see in the main code: they look different.
Sorry, but pla233 is my second account. I submitted same code in both accounts in Educational Codeforces Round 100 (Rated for Div. 2), in order to get an account of higher rate. I am really sorry for making this mistake.
Attention!
Your solution 101576941 for the problem 1463D significantly coincides with solutions yashgupta417/101564563, 11224/101576941.
Although mine and his are very similar, but we are not in the same place, how to copy? I don't believe I can find the same code on the Internet. If you think about it logically, it's just two for loops, and it's easy to see how similar it is.
I dont know why that is showing that my code is copied from someone else i did code by my self and i have evidence bcoz i write solutions in java and i submit one solution in java at 14.09 bt it shows runtime error at 5th case so i think that error is due to java and then i convert that code in c++ and submit at 14.24 u can check my both solutions it is similar so please give my rating back
i do not use ideone.com i use codeforce custom invocation to write and for checking sample test and then copy it and paste it on the summit solution . i think it's a coincidence my code matches with some other. please include me in the rating of this contest.
such a bad year
such a bad year
Okay, so a couple things: First, I don't want to get 4 notifications from one person that I was mentioned in something having absolutely nothing to do with me. Neither do any of the other people here.
Second, I'm sorry, but just being honest, it is very suspicious that you copied someone's solution for problem E without being able to solve C or D, especially since in previous contests you were only able to solve 1 or 2 problems (nowhere near the difficulty of today's E). Especially since it is known that people did cheat on this contest, which makes it even more sus.
Also, using IDEONE on public mode is cheating, since it is sharing solutions, so you should be DQ'ed even if you didn't copy from someone else.
Sorry i have published my code on ideone.com on public someone has copied my code Sorry will not repeat it again
:(
dude u are a loser :(
Sir,you told that round 693 div 3 I have done three questions but it is found coincide with a person named maheshitnitrr In question 1472A you it happens due to luckily but I am not new I have compete more than 20 contest but it never happened . So you should consider it as a luckily matching not a cheating ..
Regarding GkG!!__
My submissions of contest 1472 are skipped.
Your solution 103217882 for the problem 1472D significantly coincides with solutions lit2019039/103212550, whohet/103217882.
This question has a really trival solution and hence is clearly a coincidence. Please help MikeMirzayanov and remove this plagarism mark. This is really a coincidence, as the problem really have same solution.
My solution link https://codeforces.net/contest/1472/submission/103217882
Match solution link https://codeforces.net/contest/1472/submission/103212550
Please have a look as problem really have a trival solution
Please try to help, I literally have coded all the solutions by my own and I also dont use online IDEs like ideone. This is not done.It is literally a coincidence. Even the editorial of the problem have the same solution. Please help MikeMirzayanov, this is a false plagarism report that is being accused.
I published my code on ideone.com with default settings as public. It was a coincidence. Please restore my ratings.
My friend has introduced me ideone.com but I was unaware about something like public and private. I think codeforces should have its own ide because we know coding but don't know how to tackle with Cheaters. But still I am not sure if I choose another will my code be passed so its better to use local IDE.I only want an IDE in which i dont need to pass all the inputs of the given test case one by one is there any extension for VScode means something like codechef ide.
It does, when you open a contest you have a tab called custom invocation. Use that if you must.
Means we can run on codeforces itself with custom inputs.
Yes
Hello MikeMirzayanov, today I got this message from system saying that my solution 104287836 for the problem 1473A significantly coincides with solutions Anshika_18/104289814. For this reason I didn't got my rating. I don't know is this a coincidence or anything else. I coded on vs code and submitted. that's it. I didn't use any kind of 3rd party ide. And personally I don't know about that handle(Anshika_18). Its could be a coincidence or may be she hacked my code(I don't know its possible or not). After checking submission info I saw, my submission was in 7th minute & her was 9th minute of contest. So, in this case I'm totally innocent. It could be a coincidence or she did something evil. Please give my rating back if its possible. I have nothing like streaming or something like that to prove I'm innocent. Thank you.
Its been 2days. And I didn't got any answer. It was a clear coincidence. Its not my fault. Bruteforce solution could be same and our variables were different. hello MikeMirzayanov, please help me and restore my rating. thank you.
Did you get a reply?
Nope
Did your ratings got restored?
Sorry,Mike. My code may have leaked out in some way,but why was my submission rejected？I submit first.
Today I received a message from system saying "Your solution 105705095 for the problem 1478B significantly coincides with solutions VIS_21/105705095, S_T_A_R_K/105706095". I admit that its not a coincidence, its the same code because both of them are my accounts. It is my mistake participating in competitions without reading the rules. I'll make sure that this will not be repeated.
Hello Codeforces: I received this message "Your solution 105920108 for the problem 1476B significantly coincides with solutions Alice_Zuberg/105920108, 2304/105920197." I think I received this message is that I used two accounts solving the same problem with the same code yesterday. I didn't know the rule and I feel guilty now. Please don't block my account(even it's ranking is low due to my bad brain.) And I need to say sorry to everyone who participate in the previous contest. Sorry to you guys for letting you getting your score late.
This is the prove that the two account are both belongs to the same person.
Looks like I am not the only one who did this mistake. But I still need to apologize because I did the wrong thing. And I promise I won't do it again. And please forgive my poor English, I am just a middle school student from a country which English is not the national language.
To make sure you get my mainly message right. I will say it again. "The two accounts are both mine, please don't block them! But if you still want to punish me, then please block this one."
Hi there,
I received this message:
" Attention! Your solution 105910649 for the problem 1476C significantly coincides with solutions In_Memories_11_08_2020/105891388, not_tehlka/105903063, yinuowang/105910649, sk_loves_Ritika/105921450, rivnam/105928243. Such a coincidence is a clear rules violation. "
I believe this is because all the submissions used the same fastIO code (which has been used many times by myself as well as other users before the contest in question). The link to the code is here https://github.com/cheran-senthil/PyRival/blob/master/templates/template_py3.py. As you can see, the file was last updated in 2019.
Any help would be greatly appreciated.
Hello, so after yesterday's competition I got the following warning: "Your solution 105892973 for the problem 1476C significantly coincides with solutions Fubuki_AI/105892973, misra_17/105901746, samcpp/105933007. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation."
I am a fan of Benq's way of writing code, so I wanted to try using his predefined functions and variables. The thing my submission and the others mentioned above have in common is the predefined functions and type names. Should I change the template code I am using in order to not get the same warning in the future? Thank you for your time!
Today I have received two unexpected warnings from CodeForces plagiarism checker. The first one says, my solution 105930169 for the problem 1476D - Journey significantly coincides with solutions bleh0.5/105914875. After sometimes I got another warning that my solution to the same problem (1476D) significantly coincides with solutions bleh0.5/105914875, tejas10p/105917332.
There exists a very simple solution to the problem 1476D. So there is a high chance to match the solutions of two different persons. I have explored the submissions of the first 100 people according to the common standings of this round. Among these 100 submissions, I found 7 submissions that are almost similar to my solution. I'm mentioning these submissions here.
My submission:
The two submissions that matched with my submission:
Similar submissions:
105883915 Here only difference with my solution is I used array and he used vector.
105878527 He used vector and wrote the solution in a separate function.
Other similar submissions:
I am requesting MikeMirzayanov to look into these unexpected warnings. It's totally an injustice to me -_-
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody. What I do for that?
Well for starters, appealing a plagiarism case by using a sentence that shows up 12 other times on this page is probably not the best way.
Second, read the rules next time. When you register, you agree to the rules. If you break the rules, you get punished. So just learn from this and move on.

Why is this sent to me I MEAN ALTEAST CHECK THE SOLUTIONS BEFORE SENDING SUCH MESSAGES? I JUST CHECKED THE SOLUTION OF WHOSE IS BEING SAID IS SAME !!! DUDE HE HAS USED COMPLETELY DIFFERENT LOGIC AND A COMPLETE DIFFERENT PROGRAM. EVEN HIS LOGIC IS BETTER THAN MINE. THIS WAS NOT A LONG PROGRAM ATLEAST SHOULD HAVE SEEN ONCE BEFORE SENDING SUCH MESSAGES Please System and MikeMirzayanov give the ratings back and also check the submissions first and see the logic. Thanks

k
105934322 105919687. These two look suspiciously similar to me. Really the only difference between the two is variable names. In fact even most of the spacing is the same. Maybe you should explain that (probably with a better attitude) before asking for your rating back, and not mislead the community by claiming that it's different logic and different programs.
This is about my solution 105756399 for the problem 1478A. sorry, it has to be a coincidence. I have not submitted my code on any other platform and I am new on Codeforces so I don't know how this happened. Please restore my score.
sorry, it has to be a coincidencewhy are you saying sorry if you think its a coincidence?
it's called being politely disagreed.
It's a case of coincidence, I can't do anything with that. I performed well in the last contest and my rating shifted by a huge margin . I want my rating back .
Contest Details : Codeforces Round #699 (Div. 2) User Handle : pulkitbatra5539
I can't believe that I will be sentenced to plagiarism. I did question D step by step according to my own ideas. I read the code that is similar to me. Although the ideas are the same as mine, the code is not so similar. Maybe because our ideas happen to be the same, lead to the answers of each sample are the same, so we were wrongly judged to be plagiarized.Please give my ratings back.
Few days back, I got message that my solution moarvivek/105708333 for the problem 1478C significantly coincides with solutions Mike_patience/105755095. Anyone can see the solution of Mike_patience and tell that he has cheated. He is running useless for loops and and declaring unwanted variables. Moreover, I submitted first. And regarding the source, it was a codeforces round and one can voew the solutopm of his room members and might have shared the solution from there. I request CodeForces to please excuse users who submitted first in codeforces round or stop making rooms.
Am I right that your participation wasn't punished? The reason is exactly as you wrote — you submitted the solution first. Also, your account doesn't have a history of violations. That is why you were just informed about the incident, but no punishment followed.
I received this:
Attention! Your solution 106787586 for the problem 1479B2 significantly coincides with solutions kotamanegi/106770631, sugarrr/106778989, Rubikun/106787586. Such a coincidence is a clear rules violation.
I used this for my solution 106787586 (based on AtCoder STL).
I found a similar case
I think I'm not breaking any rules.
Could you please confirm this?
Hello MikeMirzayanov.
Do you remember this? I'm waiting for the rating to come back (before CGR13 if possible).
You (system?) say, "If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details."
But now,there is no response. Is there any other way to get in touch with the Headquarters? I do want my rating back, but I don't want to ruin Recent actions list of Codeforces with topics that have nothing to do with algorithms or problems.
There is no plagiarism between the solution Finisher_7/106840310, RohitHansdah/106841752 the matching of the solution is a mere coincidence. Please give my rating back.
How ugly to lie like that:
MikeMirzayanov Sir! For the last Div 2 contest being my code written in Ideone , I got a plag message and my contest got skipped. But my rating too decreased by 200!!!!! If its skipped it should have been unrated for me. I am really sorry for my ideone settings and I promise this wont happen next time. Please look into the matter , I want my ratings back
I use a code from gfg https://www.geeksforgeeks.org/generate-pythagorean-triplets/ So I think someone else also use it
Hi, I participated in Codeforces Round 702 (Div. 3) and after the contest, I received a message from System that said FourthThread copied my code for problem D and E, I think the reason why my code got copied is because I accidentally made it public on ideone. Can I get my ratings back because the reason he submitted after me?
Hi! Codeforces,
I got a system-generated plagiarism message with "ada000321". I tried submitting my code from this account but it was not reading the uploaded java file and I even tried copy-pasting the code but submit button was not becoming active. Then I tried submitting with "ada000321" and it got submitted. I changed the code a bit to avoid plag and submitted it with this account. It would be great if you can revert my rating.
Thanks
I got a message says that my solution 107813755 for the problem 1486D significantly coincides with solutions trivializer/107807534. But this is really my own code code, and no communication with anyone, in my opinion, this problem is a very routine binary + maximum subsegment sum, here the array S represents the prefix and is also a personal habit, very consistent with the personal code style, I think here is the detection of the machine fault, I hope the administrator clearly.
Since the solution to this problem is almost unique, I randomly found several codes that are very similar to the above two codes. https://codeforces.net/contest/1486/submission/107799424 https://codeforces.net/contest/1486/submission/107804025 https://codeforces.net/contest/1486/submission/107812317 https://codeforces.net/contest/1486/submission/107808666

About codeforces round 705(div.2) I got a message that your solution for problem B matches with the solution of some other person. Sorry but this is a co-incidence as I think the solution to the problem is unique and even I didn't write my code on some online platform. So please don't reduce my rating.
Wow, your solution exactly coincides with this regular cheater of codeforces Kaustov_584
His submission
Your submission
You along with lot of others have copied solution from telegram. Shame on you guys!

Here is the link to the code I submitted: 109859745
I wish to clarify that I used the following website as a source for my submission: https://www.geeksforgeeks.org/find-four-elements-a-b-c-and-d-in-an-array-such-that-ab-cd/
This source was last updated in November 2018, way before the beginning of the today's round (Codeforces Round 707 — Division 2). I believe that other users may have used the same source, and thus we have similar solutions. I would also like to mention that I modified the source code independently in order to suit the needs of the problem.
I would be happy to answer further clarifications.
Thank you!!
I reverted all punishments if for a user the only matched code is in problem 1501C.
Sir why are you not removing the cheaters from round 705 div 2 from the official standings.
You have skipped their submissions but still they got positive rating change.
Why sir??

I have got this!! How can you plagiarise on A The code is just of 5 lines and most coincidently the structure of code is same. Also the one temporary variable used in the code is different So I request @MikeMirzayanov sir to look into this matter and not plagiarise me. PS: I dont even know the user
We take into account not only the similarity of a particular pair of solutions but also the history of your previous cheatings. Also, we also consider other your submissions. Explain to me why you sent this problem so many times? Why isn't her solution similar to your other solutions? I think that you are still trying to cheat and I am sad about this.
Your 4 submissions on "just of 5 lines" problem A:
Sir to be honest I was logged in from that handle which I din notice and submitted it unknowingly! Else there's no any reason to cheat on A
You are just a cheater. Problem B:

The Fast-io template which I used in my code is from pajenegod Github Repo "Pyrival" [from https://github.com/cheran-senthil/PyRival/blob/master/templates/template.py]. I have also mentioned the link to the Github repo in my solution as well.
The main() function of my code is completely different from zapdospops main() function.
The top part of the code where I imported some libraries and added some functions is my own template which I am using for the past 2 years. Here is my submission link 63302879 from 24th October 2019.
It seems zapdospops copy-pasted my template from my previous submissions.
MikeMirzayanov Could you please look into the matter? Thank you!

I didnt realise the deafult setting of ideone was public. Kindly give my rating back. Wont happen again.
sir my code was caught in plagiarism although i don't have any idea about how that happened. maybe because i was using online compiler as my pc's specification is not good.
I will take care that this will not happen in future. I am extremely sorry that such thing happened with my account.
I tried running my code on ideone in default setting and someone may have copied it and I was not aware about that. It wouldn't happen again Please give me my rating back in Codeforces Round #712 (Div. 2)

MikeMirzayanov, sir, I have proof that I did not copy the code in any way.
I had two submissions to this problem: my first attempt was submission 111915223 (in Java 11, TLE) and my second submission 111917842 (in C++, AC). The latter submission is the one that "significantly coincides" with the other solutions listed above.
During the contest, I first wrote the code in Java and submitted it, getting TLE. None of the submissions listed above are in Java, so there you have proof that I did not copy my Java code from anyone. Then, since C++ is way faster than Java (especially with String operations that are required in my code), I thought that if I could change that same code into C++, it might get AC. If you examine my Java submission and my C++ submission, they are exactly the same. All the loops, all the variables, all the operations were the same. The argument then boils down to the fact that since I wrote my Java code entirely by myself, then I must have written that C++ code by myself as well since the two match with one another down to the language syntax, and all that is required is a simple copy+paste of my own Java code into a C++ editor.
Neither of my submissions were written on ideone.com, and I did not copy anyone else's code at all.
Honestly, I really don't care whether you give me the rating back, since it was a measly +16 anyway. I just don't want people to think that I'm a cheater who steals others' code for himself. I swear that all the code that I submitted were completely my own.
With the exception of symbol names, template and not using a
solvefunction (all of which are trivial changes), your code is exactly the same as these other people. Right down to thefirst = second = in;double assignments which are not actually present in the Java code. I might totally believe you if there was literally any meaningful difference in the codes.There is another theory: maybe the solution was posted somewhere and you ported their code to Java to hopefully fool the plagiarism detector. Because of the TLE you were forced back to C++, which triggered the detector.
Thank you for your response sir.
There's a reason why the double assignment is not in the Java code — if it was there, then the two pointers would point to the exact same instance of the StringBuilder, which would obviously mess up the code and cause WA.
I have three reasons to refute that theory:
I had not known of the existence of a plagiarism checker prior to this., so if this were true, then I would have just used C++.
Almost all my in-contest submissions are in Java — you can go check if you'd like.
Let's say for the sake of the argument that hypothetically, I was aware of a plagiarism checker, I copied the code, went to Java, etc. If I had taken the effort to obfuscate the code in Java, don't you think I'd do the same in C++? I understand that I am a cyan coder and will probably never get as good at CP as you red coders, but I think that given any code, I will still be able to obfuscate it so that a plagiarism checker would not be able to pick up on it if it was my intent to do so.
EDIT: Some formatting issues.
Can you disprove the claim that you don't code in Java to escape the plagiarism checker?
Also why would you use c++ if you were aware of the plag checker? to me using a different language seems convenient for surpassing the checker.. (since most plag submissions are in C++) The checker already distinguishes between different compilers for same C++ code
that is GNU C++ 17 and GNU C++ 17 (64)
with the huge amount of code in java besides the core part of the code with sufficient changes, it's possible to claim that bypassing the checker is easier than it would be in C++.
Can you provide arguments against these? Also don't say I happen to use C++ sparingly and I just happened to switch because your previous submissions show you know C++ well enough.
Against your 3rd point it's not impossible to claim that you weren't searching for the solution of 4th problem (it was relatively easier as well than usual D problems) and you either forgot about making changes in 3rd as a result or you planned on re-submitting with obfuscation once u got hold of the solution for the 4th problem. (but you ran out of time as you didn't manage to find the solution for 4th)
Well, there are many things that could have happened. Maybe you write in Java all the time. And when you decided to cheat, maybe you ported the code to Java not to fool the checker, but just to not seem suspicious. Then it's possible that you truly didn't know about the plagiarism checker. There are a lot of possibilities.
By the way, obvious cheaters say this all the time, you can count the number of similar messages on this thread.
The main point against you is still the fact that the codes are exactly the same and I don't see how this could have happened without cheating. This code is much too long for this to happen coincidentally. I just wanted to show that "I wrote the Java code before" doesn't really prove anything.
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back.****
You dumb cheater,you do not even know what is ideone.com. In case your code had been picked by someone from ideone.com then their solution would have got skipped and not yours.

Dear Sir, I don't understand why i got the mail at all. Yesterdays contest i solved 4 among which one was hacked as i got TLE due to one minor mistake ....You can check for the plag in all. I dont understand whats going on codeforces like i have solved more than 630 problems on CF and participated in 75 + contest and never got a mail something like that... I have neither shared my code with anyone...Please rejudge the submission. I write code in java and and the same logic could be implemented by many so i dont understand you logic. I got a mail for C. https://codeforces.net/contest/1512/submission/112525046 this is my submisssion , check this if plag is found remove my account from codeforces else rejudge the submission.
In Yesterday Educational Round #107 contest, for Question D
My Submission: https://codeforces.net/contest/1511/submission/112844023
Other Guy: https://codeforces.net/contest/1511/submission/112824945
The solution it is pretty straight forward, find all the pair that are different (like "ab", "ac", ...). So the solution itself become simple to implement.
I request community and MikeMirzayanov to help me, and re-evaluate the submission.
Thank you.

Not intentionally did and I don't know the rules as a noob I tried how to contest system works .This will never happen again.
Thanks.
Its your alternate account Mr Vijay ,wtf makes you believe that you are very smart to fool this community. Bloody cheaters like you have make me feel ashamed to be Indian.Shame on you.
Hello CF community, I recently got a message from the system that my code for D problem of Educational Codeforces Round 107 (Rated for Div. 2) matches with the solution of GudDay.
My solution: https://codeforces.net/contest/1511/submission/112831694
Other guy's solution: https://codeforces.net/contest/1511/submission/112854587
Here, the loops for pre-computed string generation is matching but it is highly common and very basic logic. I assure you that I haven't tried to contact the person, neither do I know him and it's sheer coincidence that this part of the code turned up to be same.
I request you to not skip my contest participation. Thanks!
Yes, the implementation was easy.
Same happen with me, my submission matches with SHUlpt.
Yeah, I'm not sure what's going... It sucks to be accused of cheating when you didn't cheat!
vish11 and shauryadixit1601 constantly cheating in all contests. Please see their submissions and there last 10 contest ranks. See this pdf for enough proof
If someone cheated on me a problem, why did codeforces skip my solutions and the other(someone that cheated on me ) considered him not participating in the round?
MikeMirzayanov The system message says my solution coincides with 4 more members even when I don't know them, my submission is 113778444 and other's solutions are : 113765969 , 113768019, 113770742, 113784580 I think due to the programs obvious approach many people wrote similar approach and that's why it's showing a match. Please have a look into this. I don't know how my code matches with so many people. Also no part of code is leaked by me since I joined codeforces, nor I cheat in any contests. I took the part of code from GeeksForGeeks and by Codeforces rules its completely valid I've also mentioned that in Competition's post, I see some losers hating for cheating, so I would ask them to check my contest history there's no allegation of it in the past.
The curiosity inside me pushes me to ask you what makes you think,you are smart to fool this community.Dumb bloody idiot cheater ,you are saying right things your code are not similar,rather they are exact same.Even the comments.I just want to hit hard cheaters like you.
They all used the
findPartititionfunction source code taken from here. Which is okay and allowed by the rules.But something else is very strange. If gigawhiz really took this code from that webpage, then why didn't he/she mention this fact? Going with "due to the programs obvious approach many people wrote similar approach and that's why it's showing a match" nonsense story is indeed very suspicious. It's almost like the solution just had been mindlessly copied from another contestant without even being aware of the geeksforgeeks.org website.

It is very tentative to take count of 'T' as t and count of 'M' as m and the logic was ofcourse simple and same .** IT IS A COINCIDENCE FOR SURE**. I swear on god neither do i know abchandan11 nor i have used any online platform, i request you to restore my rating. It is hard to give 3 hour contest and not get rewarded , hope you guys understand this. If i would have to help him i would have send all 3 answers , not only second one.

I took part in the Codeforces round yesterday, and just now I received a message saying my code coincides with someone else's. I didn't know the person at all. I solved the problem a lot earlier than him, and I didn't share my code to anyone. I think it's just a coincidence because the solution is short and the code is simple. Could you please take a look into this?

My solution and is taken from gfg's open avialabe article. As ypu can see in these pics. GFG's and Mine These state it was an pre released code. Infact after contest I wrote an comment on it and tagged MikeMirzayanov
In this case, the codes are completely the same, not only the part from CFG. Also, you have more suspicious submissions on the next round:

Problem demanded the use of partion dp for n times after removing one element from array. And thats what i have done!!
I see no violation in the rules as I have used code from the article which was published long ago
Great to know about these rules.
Will you do one favor for our country India? ,remove your profile picture.Cheaters like you make me really feel awful ,fact being i also come from India.
I never to try to discuss solutions with JackF. I even don't know who JackF is. What's more I don't have way to communicate with JackF and the system can check the chat situation when the competition.

Hello Everyone, This morning I got a message from system that my submission for 1515D thanhchauns2/114915100 during the Contest, has been found significantly similar to someone else's solution and a warning that my account may get skipped due to this. I wrote a very basic solution for that problem which was a short cut method, and it may possibly match with someone else's because no particular algorithm was applied in it and I used a saved syntax of jdoodle/c++. I request the community to help me out and make my solutions valid for the round 1515D Codeforces Global Round 14.
Also wrote this on contest blog. Got this message from System :

First of all , I do not even know who the above mentioned people are , neither did I used any online compiler . Although I agree that the above codes are similar but this is probably a coincidence because for an easy problem like this (given that there were 10K+ participants) , there are a limited types of implementations possible .
Codeforces Global round 14 I received an email regarding Solution 114918327 for the problem 1515C and solution 114941732 for the problem 1515D matched with other users. I was using ideone ide with default settings set to public and I was not aware about that. I will definitely keep this in mind for future. But this time please return my ratings back. Hoping to hear back from you.
False Accusation of cheating in Codeforces Global Round 14. Got this message today. MikeMirzayanov
My Submission: 114904088 ......His Submission: 114880136 Problem B was quiet straight forward, and there are not much ways you can write the code for this problem if you try the same approach. In this case, me and tem_shett happened to use same approach for this problem. This is just a mere coincidence, and is quiet shocking for me becasue my solution has never been skipped or hacked before. Will this be rectified or I have to lose +43 for this contest ?. PS — I had a doubt, why am I the only one between the two of us who is penalized.
same scenario happened with me and my code[submission:114892862] is almost similar to urs too.
I am quiet sure, there are many others as well in this situation. I wonder how is plagiarism checked in one-liners problems like DIV 3 A.
I had code my solution "114922024" before the submission of user "dinhsangBKA" but i forgot to submit it. There are another solution that my solution(114895826) is same with user "dinhsangBKA"(114907916), it is for 1515C. My solution for C is submitted before he submit for a long time. I think he copied my code from Ideone. I forgot to "private" it.
Plz check it. Thank for your attention!
There are another reason for my later submission is i cant access to codeforces in that time. Maybe you know that, i hope it!

Justification for 1520D this was a simple 5 line code using map earlier I had used array but I got a problem that (a[I]-i<0) so it was find wrong you can see my whole code .

I don't know this guy. Maybe the solutions coincided because they were too small considering the number of people that attempted this contest, requesting a recheck.
I had a look at the solution to the questions and they seemed fairly different especially taking into account the fact that not many lines were required for any of them. This seems to have been an issue with quite a few people in the last round. Maybe MikeMirzayanov would like to have a look at this.
Codeforces, all my code were written by me alone and I have no why I have been taken out of the competition. The logic of the 2 people can match but it does make me or another person a cheater. I solved 4 problems and one out of them slightly matched with the other person. This is very unfair and wrong.
Hi MikeMirzayanov and the concerned person who can help me out, I had recently received a mail saying:
Attention!
Your solution 115251962 for the problem 1520C significantly coincides with solutions IJ_Apps/115235205, vijay_joshi/115251962. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

I have been using Codeforces for almost the past 1 year and had a great experience coding here but I had an awful experience when I read this mail because I was never involved in plagiarism for the question specified in the mail. I don't know the user with whom my code matches significantly so there is no chance that I would have asked him/her for solution. I neither use any online IDE so there is no chance that my code would have leaked somewhere on the internet. The code written by me is entirely mine. Hence, I claim that the similarity between the respective two submissions is purely coincidental in nature. Moreover, the problem was one the starting problems of a division 3 contest and hence being a relatively easy problem, its small code length makes it more probable to have significantly matching solutions between two users who were never involved in plagiarism. Therefore I request you to look into this matter and give me back my original verdicts for the my submissions in this contest which are currently shown as skipped. I hope I'll have a great user experience in Codeforces in the future.
Thank You
Hi MikeMirzayanov, I just recieved a message saying that my solution in the last div.3 contest coincided with someone else's.

I swear that I didn't cheat in the contest, and all the codes in this contest are 100% written by me. I didn't use an online IDE. I don't know the other two users. The coincidence is caused by a trivial approach to the problem : just print all the odd numbers and then all the even numbers in order. I believe many other contestants used the exact same method too. I hope I can get my ratings back.

Yes this is the a coincidence has occurred due to the use of a common source published before the competition.I am providing the link for that source which was published in 2017-: https://github.com/AliOsm/CompetitiveProgramming/blob/master/SPOJ/DCOWS%20-%20Dancing%20Cows.cpp

There was no Plagiarism involved in these solutions.
While we have practised together causing some similarity in the code style (variable names "dp" and "Tree", function "solve") — the solution itself was not copied, and not online unintentionally either (I use sublime text, and have been for the past 6 years). And apart from the variable names / the core logic being small and similar (there are many similar submissions apart from ours) — there are visible differences in the code.
Please revert the flag on our submissions.
Thanks Prashant. Just to reiterate from my point of view, I had 4 wrong submissions on the problem during the contest, trying out different approaches before finally arriving on the right approach.
The core part of the logic for the problem in my submission involved the following 2 lines:
dp[u][0] += max(dp[v][0] + abs(a[u][0] — a[v][0]), dp[v][1] + abs(a[u][0] — a[v][1]));
dp[u][1] += max(dp[v][0] + abs(a[u][1] — a[v][0]), dp[v][1] + abs(a[u][1] — a[v][1]));
You will find something very similar to this on several other accepted solutions for 1529C - Parsa's Humongous Tree. The main source of similarity between our codes apart from this, like Prashant mentioned, is similar naming conventions for things like vector <int> Tree[N], the array with name dp etc., but these are conventions you will find on most of my other submissions involving similar data structures/ approaches.
I hope the flag will be reverted, thanks!
Thanks for reverting the flag on my submission.
Could you also revert the flag on nishant02's submissions? The contest remains unrated for him — but as shown, there was no hint of plagiarism.

Well actually I used a code from a github repo . The owner of the repo is a teacher on coding ninjas in a competitive programming course. As I am pursuing this course, and I had the same code snippet in my solution. Maybe the other guy taken up the same course from their website and used the same code snippet as well. In future I would try not to use publicly available code directly to avoid such misunderstandings.
I request you to give me my rating back. Thanks in advance!

As you can see, my results in this game are not ideal, Shimarin's results are far above mine.I was sad that I didn't have the top 100 but now you told me that I was a cheater!I was quite shocked！
Please read my following words:
If you solve the problem 1523E ，You can find that is just a problem of combinations and you can see that the combination formula is very short and easy! A skilled coders can quickly get a correct formula through a clear idea.
I get this formula by myself ，I have all the formula I wrote down on the paper during the contest and I even wrote a long solution about problem ABCDE for my classmates as soon as the contest was over!
You can say that this problem just let you preprocess the combination number and implement your combination number formula. Undoubtedly，I use my own preprocessing templates and combinatorial formulas!
You can see my submission about combinations problems before the competition： 106946007 87723842 67996018 117501164 87503641 86325813

I don't know any of these people. In fact, I don't know anyone on Codeforces. I didn't use any online compiler. The problem B was quite simple maybe that's why? This is simply a coincidence because I don't know what else to say also, this blog needs pagination

Appeal #1:
Your solution 117879400 for the problem 1523B significantly coincides with solutions Ali.Kh/117879353, wjli/117879400.
My code: https://codeforces.net/contest/1523/submission/117879400 "Significantly coincides" with https://codeforces.net/contest/1523/submission/117879353
First, they are only submitted 6 seconds apart. Then, they use different sequences 1/1/2/1/1/2 vs. 2/1/2/1/2/1 (and that's quite different insight). In addition, the code styles are different (for example, using vector instead of array). That's a lot to pull off within 6 seconds.
More conclusively, actually i wrote a piece brute-force code (below) to help me find out the right sequence (call me stupid as I had no intuition). And I have a onedrive archived file (with timestamp I cannot altercate) that proves I wrote it 3 minutes before I submitted my solution. I am happy to show it via Zoom if anyone is interested.
Anything else I need to prove?
int main() { ios::sync_with_stdio(false); cin.tie(0);

Your solution 117884135 for the problem 1523C significantly coincides with solutions Ali.Kh/117883913, wjli/117884135. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation.
My Code: https://codeforces.net/contest/1523/submission/117884135 Other's code: https://codeforces.net/contest/1523/submission/117883913
They were submitted 24 seconds apart!
Honestly I am not sure why the code is flagged -- maybe because it uses the same vector name v? (But v is a common name in the first place).
There are quite some changes in the implementation ... just to name a few:
1) I read all inputs first and store in vector before processing; the other's code process as it reads.
2) Different print out code
3) Different handling of multiple cases (I wrote everything into main(); the other uses a separate solve() function)
I agree both pieces of code use the same algorithm (and that's the one in the editorial), but make all these changes in 24 seconds?
What else do I need to prove?
Some of such alerts were sent out by accident. This including. See, no solution has been skipped in your case.
Hi, Your solution 117895089 for the problem 1523C significantly coincides with solutions Ash_/117885569, DerekFeng/117886596, ScarletS/117895089. Such a coincidence is a clear rules violation.
Although my solution (117895089), _Ash__'s solution (117885569) and DerekFeng's solution (117886596) are indeed quite similar, I believe this is just due to the simple idea which gives way to the solution. :)

Dear MikeMirzayanov, Sorry for interrupting you when you are busy in various business. I write this comment to implore you to agree with my request. I'm a participant in Deltix Round, and also a cheater in this round. I'm ashame of my behavior, and I accept any punishment. When the contest left only 1 minutes, I couldn't debug my code successfully and felt restive about this. I asked lzr_010506 to share the code to find my bugs. But actually, I submitted his code directly to skip my submissions. After this round, I known that the code comes from Roundgod, and he share the code because of lzr_010506's absence. I'm really ashame of my behavior, but Roundgod know nothing about this. I implore you to cancel Roundgod's punishment, and I accept any punishment.
I received a message regarding matching of my code with someone else code. I wrote the solution on my own. I have been submitting such types of codes for my practice and in contests. And from next time onward I will try to take unique variables and also enhance my template a bit so that it does not matches with anyone. Using Ideone was a fault and also the solution to the problem consists of dp states which are kind of familiar to all.. Please consider my grievance. I'll take care that it doesn't happens in future.

I worte a common dp solution of which logic could match to any person and one more thing half of the input class i defined coincide with him because we copied the same syntax for fast input in java from gfg https://www.geeksforgeeks.org/fast-io-in-java-in-competitive-programming/ Even my solution is mentioned in some of the comments on the editorial article. Kindly look into it and provide my ratings back. Thank You!
Hi I received a mail from codeforces that 118432155 significantly coincides with solutions. I have saw other solutions also and it is a bit different from them. It had basic logic and we just have to answer using dp and maybe because of that our code has matched. Also the editorial and video editorial were about the same which can led to same logic. I don't know how our code matched. It can be due to same dp states. Please look into the matter. It can be due to that as i have used common names for arrays.
My solution, zeddie/118430828 matches coincidently to skylag/118435215. I really don't know how this happened, I just followed the standard procedure of solving the sliding windows and it worked fine.
I have messaged him just to know how this happened. Let's see how this happened.

I got this warning 9 hours ago, I used ideone as my IDE in this contest as my IDE was not working,I forgot to make my code private , hence it might be available to the public . Moreover, my submission is at 30mins into the contest and PragChat submission is at 1hr 2mins into the contest this clears the thing that I didn't cheated .My code was original and was written by me. Following are the two submissions along with the time stamp: https://codeforces.net/contest/1536/submission/118618267: Mine https://codeforces.net/contest/1536/submission/118633707: PragChat I hope it clear things and I would request MikeMirzayanov to revert my ratings.
Please do consider reverting my ratings, I have been working hard enough, and losing rating in such a way is completely depressing when you have worked hard for your solution, and due to someone else you get your solution skipped.
I hope MikeMirzayanov finds my above explanation convincing.Thanks

https://www.hackerearth.com/practice/algorithms/string-algorithm/string-searching/practice-problems/algorithm/missing-string-c28c0934/
And solution available on HackerEarth https://www.hackerearth.com/practice/algorithms/string-algorithm/string-searching/practice-problems/algorithm/missing-string-c28c0934/editorial/ In this condition two solutions Maybe same. Please MikeMirzayanov look into it.
sorry.But i don't know how it happened.
This ayush_agrawal5 I had used ideone to code the solution in the last contest. I got a mail from the organisation regarding the similar solution by another person. This is to ensure I hadn't shared any code with anyone. But by mistake I had published the code in the ideone which I removed from there. Sincerest apologies.

A few minutes ago I got a message, "Your solution 119871998 for the problem 1537C significantly coincides with other user. "Your solution 119875021 for the problem 1537D significantly coincides with other user. I think it might be a coincidence. Please give back my ratings.
You both copied from this https://www.youtube.com/channel/UCm-7dkk1fHId1hy5vY5VVCQ channel

Hi Sir MikeMirzayanov i got this mail an hour ago .I have been falsely marked plagiarised by system checker on B and D in last contest. B was a one liner code and D was 3-4 lines so maybe thats why the code look similar. I have been participating in codeforces contest for a long time and don't want to demean the spirit of this sport in any way. Kindly have a look and tell if anything look suspicious.I have neither contacted KDVinit nor used any public ide.
That's the same case with me as well. Does that clears our suspicion @ MikeMirzayanov. It made me a bit downhearted to see this kind of a message from someone I have such great respect for.
Obviously, we don't know each other and have never had a conversation. Neither had I used any kind of online platform. I believe the reason obviously is the short nature of code for Problem B and D. Still that makes me curious why only our submissions were being suspected. It would be really very great if you could clarify the query and assure that the suspicion is now cleared.
Anyways, Thanks a lot for such an amazing platform : )
MikeMirzayanov Yes very well done sir! What should i call it ? discrimination ? or what ? same was the issue with my code and a random guy's code that due to short nature of code it is detected as plag. But u just simply ignored it ? Why ? It is because we are beginner or what ? Please clear your reason Sir. I am very obssessed...

MikeMirzayanov Sir, my submission in problem D of Codeforces Round 726 Div2 119899217 is skipped because codeforces found it as same as some random guy's solution. here are my defense regarding this.. 1. The code was short and process was same which can happen. 2. Only my structure was similar to the other which is due to the logic. 3. And most importantly neither i met this guy in real world nor in virtual. So, how this can even be possible. I request you to do what is right here and I hope my flag will be removed..
MikeMirzayanov MikeMirzayanov MikeMirzayanov pls Sir pls atleast have a look on the shortness of code pls
Hi MikeMirzayanov, a couple of hours ago, I received 2 emails saying that I violated contest rules in codeforces round #726(Div. 2). It says my code is similar to Abhac, rohit9095, dorado7, dineshreddy24, and ankit022. After this, I definitely feel that codeforces plagiarism detector works very well. Please check out 1537A - Arithmetic Array and 1537B - Bad Boy, I am sure one will come across codes with totally similar logic, as these both problems are just like take input, make comparison and print result, definitely very small codes.
Here are the solutions of problem A:119805593 119812331 119812592 119815260 119815804 119821617
Here are the solutions of problem B: 119811633 119830162 119830937 119834195 119850823 119858089
As mentioned in the mails, I have not compiled my code over ideone.com or any other online compiler as I do code on my local compiler, neither did I share my code with anyone. Please consider this as a case of total coincidence as these codes were just even less than 10 lines, one code is even just 3 lines. Moreover one could compare my submission history with other users, there cant be any similarity in submissions.
Even most of the other users have plagiarism issues in other questions of the same contest (I assume so, as its mentioned in their submissions that they are skipped, and all of them are out of competition, as currently showing at the time I am writing this comment).
I completely understand that plagiarism detector is necessary to catch a felony, but don't let it turn into something which affects innocent people!
Yeah B was just
print(1,1,n,m)for python so according to me, they shouldn't be given a penalty for B. MikeMirzayanov2021-6-11's code：https://www.luogu.com.cn/blog/jzm/solution-p6185
It's NOI Online 2020 Round 1's problem.
Your solution 119862059 for the problem 1537F significantly coincides with solutions All_Forward/119856937, royo_sea/119862059. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.ml/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties.

Answers of Codeforces round #727(div. 2) are available on youtube.
https://www.youtube.com/channel/UCm-7dkk1fHId1hy5vY5VVCQ this is the page which provide solution during contest. Its our responsibility to stay away from these kinda pages as they will never help us to grow. And I've reported this channel and I want you to report as well as lots of people are cheating from there.
NOTE: I was not involved in plagarism, and as a responsible member of coding committee, i've written this comment to inform you that the above mentioned link was active during contest hours.
Thanks for being honest and confessing. I can confirm that your submission 120103294 is indeed very similar to submissions 120103692, 120086833 and maybe many others. Therefore skipping your submission would be the right thing to do for MikeMirzayanov.
But there's also one amazing thing. When I used C-Vise tool to remove obfuscation from the kedos123's submission 120086833 (it looks like 120411468 after reduction), I could see that C-Vise decided to remove the second loop too, because this loop is unnecessary for solving the problem. This useless loop is present in every suspicious submission, and in your submission 120103294 it looks like this:
Imagine that someone shared a working solution in cheater circles during a contest and this solution contained the following comment in it:
What would happen in reality? Well, cheaters are still somewhat intelligent and will probably figure out that removing this comment from their submissions would be a good idea. Now replace this comment by a fancy looking, but entirely useless loop. How many cheaters would realize that removing this loop is a good idea?
Moreover, this loop is not entirely useless if we assume that its intended purpose was to actually increase memory usage. The OptimusPrime090's submission 120103692 used 254MB! Considering that the memory limit for this problem was 256MB, this submission was very close to failing system tests. Did the mastermind hope for stronger system tests?
Cheaters are often saying "The problem was too easy and many people came up with exactly the same algorithm, it's an unfortunate coincidence, gimme back my rating". But in this particular case, could they provide a reasonable explanation for the presence of a useless loop in their submissions?
PS. The circulated cheater solution for problem D also has similar amazing redundancies in it, which are obvious after processing it with C-Vise. If anyone is interested, I can explain what's so amazing there.
This is a really smart idea!
More than a random loop, maybe there could be a useless macro, or some complicated macro/pragma magic that would be hard to understand. Like obfuscating parts of a template so it's easily recognizable that it's been copied, but hard to figure out (for cheaters) that there are useless elements of it that give them away.
The idea of posting fake solutions to catch cheaters isn't new and it wasn't mine. It was discussed just recently (but I can't find the relevant topics anymore) and also much earlier.
Now the whole situation looks like someone is repeatedly trying to make a shot at failing system tests, but unfortunately misses again and again. For example, chutiyacheaters reported that cheater solutions had been provided for Codeforces Round 728 (Div. 2) again. This pastebin shows a leaked solution for problem B. The solution relies on
sqrtcalculations in a loop, which is a known bad thing to do. When submitted by kedos123, it took 1716 ms (not very far from TLE). All these recent leaked solutions look clunky and I think that this was intentional. But maybe it's my confirmation bias :-)Still the cheaters apparently happily swallow baits again and again. We may use this chance to catch them all. The useless loop, discussed in the previous comment, is a recognizable marker. I think that I can create a code to search for it in a way that is obfuscation resistant. But first it's necessary to download all solutions submitted to recent contests via the codeforces API.
I got a message regarding significant matching of my code for task B, with a lot of people. Some of them have submitted the code in C++, for task B, while I have done in python. Plus, I have not referred to any other source. I plead not guilty. Please, un-skip my skipped solution.
you've copied the code for problem D from youtube and just changed the variables name in c++ despite the fact you write code. in python
Hi, I recieved a mail from the system that my solutions for 727 div2 round A and D coincide with a bunch of other people. I never have copied uptil now and would never even think of copying. Just because some implementation details due to the question being of straightforward implementation type doesnt mean that I plagiarized. MikeMirzayanov please consider this, I have never plagiarized before (you can check my history) and would never even thinkto do so. There might be some mistake. Please consider this urgently. Moreover I dont use ideone or any other such website to host any kind of code MikeMirzayanov . Also this is the first time I have got such message. I dont know what to do and dont want my ratings to drop without any reason.
Appeal for A : I already had got a lot of WA's on pretests on finally got it on the 4th attempt. You can see that my solution is progressive toward the final solution which being just a simple formula coincides with so many others.
The rest of the contest : Then I first solved problem B(45 minutes) and then directly jumped to problems C and D to read it. In the process I did simultaneously code the solutions to C and D and also got some WA's on C before submitting. I was almost sure of D so I submitted it alongwith C (just a few minutes later) which luckily passed. Now my guess is the structure of D code is coinciding with many others so it may have got caught in the plag check, but it is a complete coincidence just because of the difference in times. Those whose codes have caught(C and D) are mostly last minute submissions but I had almost 20 minutes left in hand, the time for which I spent reading E.
So MikeMirzayanov and geranazavr555 I humbly request to please look into the matter.
Ffs stop lying.Clearly your solution for C and D matches from those leaked solution on youtube.Have some shame !
First of all have the guts to comment from a real account and second of all many people have been falsely accused of this ideone stuff so please just stay out of it if you have no business here.
falsely accused ? lol your submissions exactly matches from leaked solution. You just changed array to vector only thinking you wouldn't get caught.
There are numerous such instances where the code matches with intended solution may it be in logic or implementation. Doesnt prove anything. Also look at my submission times and penalties. Are you really that dumb to think that a even by chance if I had any assistance I would let that many penalties occur?
Can't argue more with you shameful cheater.It can not possible that 2 or 3 solution exactly matches with same idea and implementation.
Harsh18064 this user was cheated why he still rated ? MikeMirzayanov check this
Dear cheater hunters. If you really want to help to eradicate plagiarists, then please:
Don't post any links to the original sources of the cheater solution. Neither during contests nor after them. This is pretty much useless and doesn't help.
Do publish unmodified master copies of the cheater solutions after the contest on pastebin or ideone. And post these links here.
Or even better, create a throw-away alt account and use it to submit unmodified master copies of the cheater solutions to the codeforces judge system during contests as soon as they become available. Such accounts will be easily flagged by the plag checker and they can be also used as a proof of cheating with reasonably reliable timestamps.
Hi!
I received a punishment from the system which claimed that I had cheated with romanychev, but I didn't.
Attention!
Your solution 120543231 for the problem 1541A significantly coincides with solutions romanychev/120536673, sepehrking/120543231. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

In case of repeated violations, your account may be blocked.
As you see the codes generally have similarities, (which has became accidently) but they are not the same!!
And why should a question with a simple algorithm be copied!
And why should I do an wrong submission when I have copied it.
And why should I not give other solutions meanwhile he hasn't submitted them (he hadn't accepted any other problem except the one which has been claimed as an cheat) and had helped me.
Dear MikeMirzayanov. Please do something because it has been a misunderstanding, and it's too bad to lose the chance of becoming an expert just because of a misunderstanding.
Hello, I just received a mail regarding code being similar to another user. I am not aware who the user is neither do I have any contact with him/her. The question was a pretty straightforward pattern based one, it could be a meagre coincidence. I hope there is no action taken against me as I have not violated any rule. The history of my current account can be used to prove the same.
Hi Mike Sir, I have received a message regarding codeforces728(div 2) stating: Attention!

I have a conclusive evidence that this coincidence has occurred due to the use of this common source published before the competition. The common source is method 1 using min heap in this geeksforgeeks link at https://www.geeksforgeeks.org/smallest-derangement-sequence/.
I request you to please verify this and remove this violation charge from me.
Thank you
I received a mail saying that my solution to problem 1541B coincides significantly with this. This is a sheer coincidence since the code for the problem is quite straightforward once you know what to do. I have no relation to the person with whom my code matches. Also you can check my other C++ submissions and account history to verify my coding style. Please drop the rules violation charges against me.

While I do not have any "conclusive" evidence, I would like to point out that I have never contacted or spoken to either of these users. I believe that the similar submissions are due to the nature of A being an easier problem, and I think many people who have similar syntactical habits with the same idea for a solution could end up writing the same code. In this case I made the observation that when N is even, you can simply swap each pair, and when N was odd, you can swap every pair except for the last 3 which you would cycle. I'm sure these other 2 participants could have drawn the same conclusion, and with the limited variable names ended up writing the same code.
Unfortunately, the same thing happened:(
The same of yours, I submitted a wrong solution after the other person has accepted it!
And if I was a cheater why did I submit a wrong solution!
And my only problem for the wrong solution was 2 characters, so why should I copy paste for just 2 characters when I have an algorithm!
Unfortunately no one cares, and I am sorry to say such a thing:(
in codeforces round 730, I got plagued for question D1 with some unknown person, our templates are very same maybe because of that it happened, but the core code is of 6-7 lines and its very different can I get my rating back
The plagiarism occurred as I had the same template as that of the user "satvikb." I really liked the template, and I used the template for all the questions. I was completely innocent. As the question was basic and with the same template, it became more prone to plagiarism. And also this contest was really important for me so I want that this contest should be made rated for me.
Hi, On the previous contest, I was flagged twice with user Gabp on problems B and D1. On both problems, the codes were very short and the logic very straightforward, variable names are different, code-convention is different, but the control flow is pretty much the same.
I don't really care (and I guess he doesn't either but I don't know him) if my participation is counted or not as I am an unofficial participant. But how to avoid that in the future ? On very simple problems like that, I feel like it is easy to have two very similar solutions... And I don't know how on earth I could prove that I didn't cheat ! And I don't really want to start "obfuscating" my code to make sure no one has a similar solution.
Here are the submissions :
121606777 vs 121614251
121577903 vs 121577396
Notice that on the first problem, I submitted before him while on the second one he submitted before me. It seems like we just have a similar coding-style.
Hello Everyone, This morning I got a message from system that "Your solution 121583473 for the problem 1543A significantly coincides with solutions leeroy_a3k25cvp/121583473, DuyAnhTM/121605069." during the Codeforces Round #730 (Div 2) and my account my get blocked due to this.
Both of the submissions were made by me for Question A, and i was thinking that the earlier one would be ignored as we have in any normal Round.
I request the community to help me out here as I don't know whom should I contact about this.
MikeMirzayanov Sorry, I shared my code with saitamaa during the contest. I regretted it after helping him, I promise, I won't do it again. Penalise me if you think it is fair, I am sorry for my behaviuor.
My code:121229572
Their code: 121240196
I code on ideone in public mode. Many people took my code so it was duplicated. I hope AD will look into this matter.
my solution 121242428 for the problem 1542C was found similar but that is purely a coincidence. I checked the solutions of others and they have written the code in C++ whereas I use Java or Python for my submissions. There is no way I could have copied the code. I build my own logic and implement it in Java. I use fast I/O and PrintWriter for printing which is not available in C++. Therefore I request that my rating be restored as I worked hard and wrote all code on my own.
I submitted the same code twice and it got plagarised. It says "your submission conincides with jalanprakhar's submission":(.
Hello, I received this message today — Your solution 122499958 for the problem 1550C significantly coincides with solutions Hugf/122490624, Dayu2001/122499958, PotremZ/122502985.
I promise I had not shared with anyone.
First, I don't even know these two users.
Second, this problem has a special nature. When using the same enumeration idea, the code will have the same conditional branch statement, which is very normal.
Third, my code had my own style with some special templetes.
Here's my code.
Please remove the penalties that have been placed on me.
just COINCIDENCE.
I dont know why its showing the solution matches with others.i just took the hint for the B from a group but coded the answer myself.please check
You really have a warped perception on how competitive programming contests work. The thing you said you did, is considered cheating. Is it that hard to understand that you must work by yourself and should not even ask for hints? Plus even if you only got the hints, how in the world did the plagiarism checker catch you? The false positives are very low, but even if you fell into that small percentage, you literally said that you took hints from a group, like please be honest with yourself and just write the contest honestly without getting any help. Even then if your code still gets plagiarized for some weird reason, then you can plead for help, but in your case nobody can really help you because you admitted that you cheated in your words. So please, next time, JUST PARTICIPATE HONESTLY WITHOUT GETTING ANY HELP FROM OTHERS. I cannot believe the number of people on this platform with this kind of mindset. You cannot simply get hints from others during a contest.

Dear MikeMirzayanov, I received a systems message that my code matches these many people.But after going to almost many of the submissions I could clearly find that absolutely none of the solution matches my solution for D. For sample you can see this My submission->122833485 JaySharma1048576 submission->122805324 . Please revert the decision sir, because it is false plagiarism.. T_T
Me too sir MikeMirzayanov you sent a message that my submission for D matches JaySharma1048576 my submission --> 122857607 -->
his submission --> 122805324 --> Please revert the decision Sir pls :(((((( it's just a misunderstanding !
Just when your blog backfired, you deleted it!
This guy had written a blog on the same subject as this comment and deleted it after I wrote a comment there.
The comment was:
The fact that you suddenly decided to change your writing style from multiple lines to a single line in a matter of 10 minutes and also during the last 3 minutes of the contest, is in itself, surprising.
Regarding the code-matching, I am not interested in that much hard-work, so I prefer not to debate. :P
Now, guess what E404_Not_Found, you can't delete a comment unlike your dishonest blog.
I just saw that i'm getting downvots for nothing, now i deleted it.
Yes I think that this is a misunderstanding. I have checked some of the solutions mentioned above and none of them matches mine. I don't even know any of these users. Moreover, I had submitted my solution way before any of these. So, there's no way I have cheated. I hope you will look into this matter and all of us will get our rating changes back.
Edit — My solution has also been plagiarised against the solution of sethhritik. I agree that it is quite similar to mine, but I clearly think that it is a coincidence. The solutions are quite small and the idea behind the solutions are quite natural. So, there is a high chance of such a coincidence. Moreover, I don't even know the user and our submission time is not even close (there is a difference of more than 1 hour). I have given around 80 contests and my record clearly shows that I am not a cheater. I have even been the problemsetter of Codeforces Round #730. I don't think anyone will agree that the setter of an official rated Division 2 round will ever indulge in cheating.
I believe that JaySharma1048576 cannot be a cheater. I know him personally and I am damn sure he can't do this, it must be system fault. MikeMirzayanov I request you to please look into the matter.
There's no other way we can prove ourselves not guilty other than that we don't know each other and that our submission times are way different. I have tried it on my internal editor and that's what I have as prove nothing more than that. I have been participating since 2019 and have a clean profile and also JaySharma1048576 do possess a good profile. JaySharma1048576 has even been a problem setter of an official Codeforces Division 2 round and that is more than enough to prove his credibility. It is just a coincidence that our solution is kind of similar. I request Codeforces officials to look into this matter and help us with the best possible solution.
You do all the problems in PyPy2 and suddenly you decide to use C++ only for problem D.
That is because I was encountering problems with using sets in python. I switched on to cpp, as sets are mutable in python. This time I realized that most of the plagiarism is on cpp so from next time I won't switch again.
Any more stupid reason? Just admit you cheated.
Can you tell me that did I cheated if we don't know each other? Are there any more solutions matching ours? And if I pretend to cheat that I would have done it in another way not just copy-pasted it. I know that I don't have any proof to show I am not guilty. You just hiding your identity by not even having a submission in the contest and claiming I have cheated.
Yes , you can copy the solution of someone even if you not know him. And You MF have copied the solution definitely because some one have leaked the solution of JaySharma1048576 See Blog for Proof and you copied the solution from either from ideone or from telegram. So Please Just STFU.
There's no way that JaySharma1048576 has cheated as I know him personally. On the other hand it is worth noting that one of the accounts accused were in his room and also locked the problem. So that might be worth looking into.
Now I think that I have a possible explanation for it (thanks to towrist).
stopcheatingmyself was in the same room as mine during the contest. I had submitted my solution at 0:44. He submitted his solution at 0:57 and immediately locked the problem. He then probably saw my solution and leaked it.
MikeMirzayanov please look into this matter as I have been accused for no fault of mine.
Hi , Mike I got a message from System that my solutions for D as similiar as Jaysharma1048576 . can you check it once again for your clearance that both solutions are totally different.And revert my rank . Please look into this matter.
Then why have you obfuscated your code???? 122839082
I don't know how it is possible today i received an email saying that my solutions to the problems 1530B,1530C,1530D matches the solutions of many participants but i didn't used any unfair means to solve the problems,I used Code chef compiler to solve the problems which i don't think make your codes public please help me regarding this and to whom i should report this to. i didn't lock all the solutions in the hope that the y will be locked in the end automatically but i am completely certain that nobody has copied my solution i was giving the competition alone and with full honesty please consider them these are my solutions which are plagued 122809137 122793497 122832273
sorry i shared my code with stopcheatingmyself i regret doing that and i won't do it again. I am new and didn't knew it sorry. their code : 122788672 my code : 122834880
"Your solution 123297990 for the problem 1553B significantly coincides with solutions rkm62/123295031, krm24/123297990." Got a system message saying that my solution coincides with rkm62. Problem B was a simple brute force implementation: For all subarrays go backward and check it with the second string. As the approach is same our code coincided. I don't need to cheat for a B problem when I can solve till
DC.Please revert the decision back even though I fear my D will fst.
Edit: Yes it does fst and still I want the decision to be reverted.
MikeMirzayanov please look into this.
Stop Lying man. Just look at the usernames of both accounts krm24 and rkm62. anbody can notice that both are your accounts and you are trying to not get penalty and in hurry you just changed the variable names in solution of B and submitted the exact solution. Stop Doing This Man.
I suggest you to do a little bit of work before accusing someone of something. Do you really think I wasted my time to think two approaches for C and then had the time to do D that in such a limted amount of time( I am no LGM ).
Also Check out the common contests and their submissions if you are so hell bent on making this accusation.
https://codeforces.net/submissions/rkm62/contest/1542
https://codeforces.net/submissions/krm24/contest/1542
He couldn't do problem B. Or do you think I forgot how to change variable names ?
https://codeforces.net/submissions/rkm62/contest/1541

Again I am making two approaches for same problem(problem B), grow up kiddo !!
https://codeforces.net/submissions/rkm62/contest/1514 https://codeforces.net/submissions/krm24/contest/1514 Check problem C , it again has two approaches, the time stamp of problem A is same.
Maybe check my codes with your original account, you might find some similarities because to do a simple implementation you and I both may have thought of the same approach.
Now one suggestion: When you are convinced that both the accounts are of different people, man up and apologize. If you aren't convinced then comment with some real proof.
I will give you more proof such that you learn to think before commenting. https://codeforces.net/submissions/rkm62/contest/1509
https://codeforces.net/submissions/krm24/contest/1509
Again there are two different approaches for problem B submitted around same time stamp.
While I was working on problem C , he had already done C and was doing D. Can You explain this? How I am able to do so ?

I got this System message last night. Clearly, this is a coincidence. I never support these types of acts. But, I think neither of us has cheated because Problem B was a simple question with brute force solution. I have checked both the solutions, but as the problem has a simple brute force solution, so it might had happened with some other participants as well. So, MikeMirzayanov kindly see to it.
I have not seen anybody fool like you. Stop Lying man. Just look at the usernames of both accounts krm24 and rkm62. Anbody can notice that both are your accounts and you are trying to not get penalty and in hurry you just changed the variable names in solution of B and submitted the exact solution. Stop Doing This Man.
At least, I don't have to use fake account to comment. I have seen post on cheating on Codeforces many times, and idiotic people like you just learned this from Codeforces. Yes, our handles are anagrams but his maximum rating is Candidate Master and I am only capable of maintaining Expert.
It is hard to trust to krm24:
I accept these two accusation. I did share the code in the first pair and in the second pair both of them are my account.
LMFAO
Hi MikeMirzayanov. I don't know about the history of this guy. But, I can assure you from my side that I was not involved in this.
I received this message "Your solution 123740118 for the problem 1552E significantly coincides with solutions sunsiyu/123740118, C137/123745487." I code on local vscode and never upload my code to any website or server except codeforces. I think it leaked from your hack system or maybe I'm hacked.
I don't know him at all, because question B is a simulation subject for classified discussion, so everyone's logic of circular judgment may be the same, and you can see the submission record, it is obvious that I submitted earlier than him, so why was my score deducted? This is just because the title limited the practice, it does not mean that we have plagiarized, it is just a coincidence
This is my submission: 124319124 This is his submission: 124327843
For me, this deduction of points is completely unnecessary and illogical. I hope you can make a new judgment, which is very important to me. Thank you very much!

I wrote my solutions by myself and I didn't share it with anyone I read some codes form those I know some of them are similar to my solution but about 30 solutions similar to my solution this is not cheating a lot of contestant wrote the same solution! please fix this problem, it's clearly not cheating

Points that I'd like to mention in my support are--
I do not use IDEONE or any other online editor for coding.
I only use Visual Studio on my personal local system.
I do not need to copy solution of A, If I can solve B,C and D1. (A is easier than these)
If the problem is very easy, Many people can come up with same approach.
I've submitted the code within 5 minutes after contest started.
Please look on this. I do not want my account to be blocked. Thank You very much.
Hey,I come here to explain my similiar solution in last div 2; Actually ,I was very amused when I saw the e_mail. Thus,I go to see the similiar solution and find it is really alike; However, an evidence can confirm my innocence. In the solution 12590491 by skyblue02,he used pair. And you can go to see all my submissions since I used codeforces,I never use pair; In face , the problem 1599C is a very easy problem ,and the solution is single. So i think it is just a concidence; thanks for your reading and hope you can reply me soon.
yeah, I've got same message. I was surprised that submissions skyblue02/125970491, ganyu/125971616 for 1559C was alike. In solution 125971616, he used local variable for the first and second line input. I always define n(size of array) as global variable. Also, I don't define for (int i=1;i<=n;i++) like this. If I have to use i,j more than several times, I don't define variable inside for statement. I define it below main(). Like he said above, solution was single so that code was alike. I hope my account not be blocked. Thank you.
I recieved a message from system saying that my solution to yesterday's div2-C was too similar to SunTakesTooLongToDie's. However I have no clue who SunTakesTooLongToDie even is.
My submission: https://codeforces.net/contest/1559/submission/125963558
SunTakesTooLongToDie's submission: https://codeforces.net/contest/1559/submission/125962649
I think the reason the submissions were flagged is because they both used the heuristic algorithm for finding hamiltonians paths presented in this blog.
Other than that our code has nothing similar.
MikeMirzayanov could you fix this?
Hi,codeforces. Your solution 126003692 for the problem 1559D2 significantly coincides with solutions tyin/125999886, jujimeizuo/126003692. Sir,this problem is basically combined search and greedy, the code written is basically the same, so I think there is a certain coincidence, and I compared it, except for the combined search and other templates, there is not much similarity. So I hope to recover.
Why? solution 126003692 and solution 125999886 are similar, but I think I only want to get the same idea, the code written is almost the same, and it should not be 100% the same, such as the template I used and the storage of the answer. , These are not the same, I believe these aspects are coincidences, and I also believe that the ideas of the two codes are the same, so please return the scores, and the deductions are too outrageous. Thanks, MikeMirzayanov.
Hello Codeforces, I got a message from the system that my submissions of problems A and C of Codeforces Round 738 (Div. 2) matches with submissions of Jackylkk2003.
My Submissions: 125935407, 125965539
Jackylkk2003's Submission: 125935804, 125951873
I think problem A and C were very trivial problems and it is just a coincidence, so I request Codeforces and MikeMirzayanov to not skip my contest participation.

This is the first time it had happened to me , i do not even knew about these kind of issues. I did my coding part in ideone.com and i don't know how it got copied , i promise this is the last time , it will not happen again. This was my last mistake like this and i assure Codeforces that this will not happen again. Although this does not affect my score, my friends will think I participated in cheating, which is very bad. Please give me a chance, please
Sorry but it was a coincidence, I published my code on ideone.com that's why the problem has occured.
I tried running my code on ideone in default setting and someone copied my code and I was not aware about that.
It won't happen again.
Please give me this chance. I promise it won't happen again, otherwise I'm willing to cancel the account

Today,I got a message from system whose firt 2 lines were- "Your solution 126867937 for the problem 1561C significantly coincides with solutions ultizet/126864317, dumb_boi/126867937." I would like to clarify that I use codechef ide to code my solutions and that code can only be viewed by signing in to my codechef account. Also,my code was pretty basic and I hadn't taken help of any online resource to come up with the solution idea or code or anything. The message said that I must post my clarifications as a comment (but it wasn't specified which blog i have to comment to,so i assume that blog is this.If i have to post somewhere else,please specify) Also,since the code was solely mine,I don't have any evidence of any online resource so I don't know how to prove my honesty except for the fact that the problem was pretty basic and there was a high chance that 2 solutions match coincidentally. Also,my ratings were rolled back. This hurts as that contest was my best contest till now and I had crossed 1800 for the first time :( . Now, it hurts knowing that I might not get those rating points despite no fault of mine.
Hey codeforces,my solution 20je0022/127386406 coincides with the submission of Snipex111/127388985 because during the round i pasted the code on a chating app instead of submitting it.The mistake was identified by me seconds later and corrected later but the recipient of the code pasted the similar code .So i please request you to please grant me one chance as this was a one time mistake.You can see that i used the same template and coding style for the previous submission whereas the other person clearly have copied me.I have messaged the person(snipex111) and he is willing to admit it.Therefore pls forgive me for this mistake.I will not repeat the same.
.
Today I inexplicably received an email saying that my submission for 1556D 127371318 and 123zzz submission 127368540 are very similar. But I don't know this person, and I have never copied its source code. This is a very simple interactive question. Since I was too lazy to write functions, I wrote a few more identical parts, which resulted in our codes being very similar. But I can assure you that I did not copy his source code or know him. I believe that many other people also wrote this question very similar. Please check my source code again.
Please Help me about rules violation:
Maybe some people copied my solution in their virtual contest but codeforces caught my solution as a violation. I have participated in the main contest but they copied my solution in their virtual contest without my concern. My rating has decreased rather than increase. What should I do right now?
Round: Codeforces Deltix Round Summer 2021 [Div.1 + Div.2]
Please check the times:
Steal code : Virtual Contest
My code : Main Contest
First change your profile pic by removing this scoundrel wretch . Secondly, do you think we are dumb or what??? A "virtual contest" of a contest is not possible during the live contest duration(which is evident from the time stamp of the "stolen code"). 100% matching code for the problem. Even your problem A has a 100% match. Which goes to show that you either shared your code during the live contest, or copied the code from a common source online(which is the case I feel, you have a previous history of skipped submissions as well). Shameless and pathetic!
Hello, codeforces. I'm so sorry that I copied my classmate's code in 1567E for the rise of rating. This is an intolerable behavior. The punishment it brings makes the first three questions I seriously wrote skipped. I feel very sad, but I also learned this lesson. I promise I will never break the rule again.Could you please not freeze my account? I want to continue to practice and compete on this excellent platform.
Thank you.
Although My English is poor, I sincerely hope you can forgive my fault.Thank you again sincerely.
Just don't Do it next time you will be alright to go! BEST OF LUCK! AND PRACTICE HARD
Thank you for your wishes！ I will live up to your expectations！
I received a mail saying that my solution of problem b akshaywairagade2/127975091 coincides with great_fortune/127943158 but he is from russia and i am from india and neither i am using ideone .

Hello MikeMirzayanov!
On September Fifth, I participated in the Codeforces Round 742 (Div. 2). And my classmate JackF participated in the contest, too. I couldn't solve the problem F but he solve it. So I secretly copied the code to my computer while he was away, and then submitted it after changing a small part.
This is his submission and this is my submission.
I admit that I cheated in the contest and stole his code, causing his account to be blocked by mistake. I realized that my behavior was wrong and did not follow the rule of the contest, so I am very guilty and sorry. I was wrong, but he was innocent. Can you unblock his account JackF?
Thanks!
Hello community. I got a mail today stating that my solution 128258574 for the problem 1569B significantly coincides with solutions of rahul-69/128246763, midoriyaizuku/128248386, susamogusbob/128250325, avinash1320/128250570. I would hence like to appeal , that in my case ,the question for which I was plagiarised was a pretty straightforward and easy one, hence it cannot be anything more than pure coincidence that our solutions look the same. I always run the code in my local compiler, so there`s no question of leaking the answer also. Hence, I would be highly obliged if my answers are once again validated. Thank you.

The variables and coding styles in both the codes are significantly different. A common algorithm should not be held liable for rules violation. kindly rectify the error.
Subject: Coincidence on problem 1566C
Dear Sir/Madam, I just got a complaint about the code of the night like someone else's. I think you're wrong. I'm sure my code was invented and written by me. I just saw the post (Derick126/128613913) that you think is the same as mine (erwin2409/128619707). I don't see the same anywhere. You can also look through all my posts, which follow a style of my own that is unlike anyone else. I hope you check back more carefully and answer me soon. Sincerely! Erwin
I think it is easy to come up with similar ideas as my solution and erwin2409's, and we came from different countries so there's no way for us to discuss / share codes with each other.
Since it is a greedy approach, every one with the idea might implement the way I did, so the coincidence happens simply because we got to the same approach, not cheating.

Hello codeforces, I got this mail but I didn't plagiarized from any kind of source and the mentionedsubmission also seems different style of coding not match at all. I think there is some mistake by the system many other coders has also faced the same problem. So I believe I don't deserve to get penalized for this. Thanks..
stfu and stop cheating
it is almost the same,
you didn't even remove the comments lol.
Why should change my code someone has copied my code.
this guy submitted the same solution before you
your submission: 128661330
submission of someone else: 128658150
admit it you are cheating.

Hello, I recieved a mail said that the my solutions 128610687 for the problem 1566C coincides with solutions 128609558.
But the coding style and variable names, even nations are significantly different.
These code are submitted in the competition. I didn't post this code on any blog or ideone or similar website.
How can I get my score back?
I use VSCode to write the solution to any problem. I don't know how it got released but one thing I know for sure is that I didn't cheat. You can see my past submissions too, it will reflect my writing pattern. I know that it is possible for anyone to get a code and cheat but it is also a possibility that code for 2 persons match. Regarding the last code forces global contest, I got the mail today that it matches with 3 others. I have been trying to figure it out myself how it could match without using a public ide. Can you please look into it and help me MikeMirzayanov
This comment is in regard with a mail I received today saying that my submission was similar to that of another user in the recent codeforces Global round 16.
Attention!
Your solution 128615582 for the problem 1566C significantly coincides with solutions newbie0709/128615582, SimmonDobber/128621128. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

In case of repeated violations, your account may be blocked.
I use sublime text on my windows machine to code. I have never used ideone to run my code, nor have I used any other online compiler. I always use the code editor sublime text on my machine. I am clueless how this user's code (who is from a different country altogether, I hail from India and ze is from Poland) is similar to mine. Also the problem in consideration is fairly simple and straightforward, and so I believe this is a pure coincidence. My code is the simplest approach that came to my mind and so I coded it out and submitted it. Both our codes are formatted similarly and that is the reason I guess they look similar. I use SublimeAStyleFormatter package in sublime text to format the code when saved. I have not cheated in any form and I don't deserve to be penalised for this. I request MikeMirzayanov sir to please look into this matter.
sry
stfu cheater. So you are telling me that this is your solution? Tell me how can a person use 3 different languages to submit 3 different questions in a contest. Ridiculous.
How the fuck do you expect to get your rating back when you are straight away copy pasting the solution. Disgusting piece of shit you are.
Quit codeforces, its not for you. You will never be able to solve even the first question by yourself. You should even quit coding and rethink about your career.
Asshole.
I think to confirm that wheather I have cheated or not you should see submission time of my code and others code Matching with me moreover I have written my name and my I'd on top of my snippet source code.so please don't punish me For this. Moreover you can see there I have done wrong submission for (b) five times 1 st time wrong on pretest 2 and 4 times on pretest 1 Only mistake which I was doing was considering left shift as right shift and when contest was over I changed my code a little bit (Nearly same) And got accepted.My point is that I haven't got ac on (b) in contest even after giving Nearly 1 hour ,if you are accusing me for cheating I could have easily asked my College friend Who got 98 rank but I haven't (because we never disscuss during contest). moreover my rating is going to be same as predicted by CF visualizer .so don't take any such action against me because it gives bad impression about me in my group.
my rating in this contest decreased by -6 . use some common sense why would i cheat (c) and not b even having ample amount of times. i know one thing for sure my code is not going to run in every ide as i have deleted some of mine mgw internal file .so if any body have cheated from me its code is going to same .so you can most probably match the template of other question submitted by others participant whose code is matching with me. if anybody have different template for different question it surely mean that this person have done cheating
Hello Mr.MikeMirzayanov, I recently receive a mail: Attention!
Your solution 130172739 for the problem 1579E2 significantly coincides with solutions QrH/130138310, Murabito-B/130149104, Mamba0Z/130172739. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).

1: I admit that Murabito-B used to be a teammate of my ICPC. We were responsible for the data structure together, so maybe many of our templates and writing methods are somewhat similar. 2: I think E2. Array Optimization by Deque this time is a very templated problem, tree array + discretization, the only slightly novel point I think is ans += min(query(n) — query(a[i]), query(a[i] — 1)); 3: I don’t care about the score, I just want to say that I did not copy other people’s code, nothing more 4. I want to know the duplicate checking rules of codeforces, so that I can avoid popular writing according to the situation when I write this kind of template question next time
My English is not good, these are all translated using Google Translate, thank you for reading
Attention! Your solution 130701249 for the problem 1592B significantly coincides with solutions jughead__73/130701249, M_20x/130712659, susamogusbob/130713200. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. I don't know how this is possible.I dont't know them personally as well as you can see that submissions of susamogusbob has been skipped many times. Even though in the prevoius contest he had submitted using different template. I had used VS Code IDE and also I didn't give my solution to anyone, then how comes these both Id's have the same exact code of mine including my code-template. The sole reason of this would be the account got hacked. I can't see any other perspective about this thing. I've using CF for the past 16 months now. This is the first time this incidence have happened.
Please look into this matter.
I noticed that similar codes were leaked for 1594c question which has lead to same code of many participants. Moreover there are traditional code snippet of doing the fast exponentiation which were used by many that have lead to similar codes. Please look into the matter.
by mistake, i think i have have used ideone in pubic mode to compile my code in codeforces round 747. And someone may have copied my code. I will try to avoid any online ide for any contest next time.
I am so sorry i don’t know that is cheating or against rules … it was my second account i can give you username and password but i was practicing in my second account to join my primary .. that will not happen again … i swear that my code what shall i do know MikeMirzayanov Round 747 div 2
Hello, This is ashish gupta, Both userids ashish_gupta1999 and maitashish.199988 are mine, by mistake i started contest Educational Codeforces Round 115 with maitashish.199988 userid instead of ashish_gupta1999(regular) userid, that's why this coincidence happend. I really appologize for this and it will nerver gonna happen again.
Sorry, Regards ashish_gupta1999
I got the message that my solution coincides with Hazgan's solution for the problem Edu #122 problem C.
My submission: https://codeforces.net/contest/1598/submission/131406821
Hazgan's submission: https://codeforces.net/contest/1598/submission/131404187
I know the solution is mostly the same but I have not cheated. I wrote all my solutions by myself on an offline IDE. I am also sure I have not leaked my solution. It's just because Edu #122 problem C has a simple math solution, it's just trivial implementation using a map and some math formula.
MikeMirzayanov BledDest Please have a look as problem really have a trival solution.
Also including photo of math I did during contest.
Hello please help me out. Just now I received a mail that my solution of problem 1586B of
Codeforces Round #749 (Div. 1 + Div. 2, based on Technocup 2022 Elimination Round 1) conicides with user 1928311. First of all there is no chance of my solution getting leaked to any one because i didnt shared it. Secondly, kindly see the submission time of his solution , I submitted that at 17:21 and he submitted at 17:45. How could I cheat then. Please help me regarding this.
About my solution of 1586B and 1586D,I just use the same fastio as peterwuyihong，and the fastio can be found at https://www.luogu.com.cn/paste/1hec3w24.So I think that you shouldn't block my code.
I have not copied someone else code. I am giving about 7-8 hours from last 6 months to codeforces to learn and solved about 1000 question in these 6 months.
Please admin check why my solutions had skipped in last div3 contest.
MikeMirzayanov sir please reply
code
but your code looks just like the leaked code that everybody copied.
I feel sorry for your 7-8 hours of effort in the past 6 months. haha
Hi Everyone, Today I got a message from codeforces that my submission https://codeforces.net/contest/1586/submission/132224477 during the https://codeforces.net/contest/1586, has been found significantly similar to https://codeforces.net/contest/1583/submission/132222014 and I didn't get any rating because of that. I am sure it's just a coincidence. I wrote a very basic solution for that problem, and it has matched with terraborg. It was a very basic solution to that problem.
I request the community to help me out here please and make my solutions valid for this contest.
YOUR CODE
LEAKED CODE
if you are innocent, then why does these two codes look the same??
it's because you are just a fking cheating piece of shit.
you cheated, and now you are still lying.
please be ashamed of yourself.
In today's round (750 div 2), I had an extremely similar solution to D compared to https://codeforces.net/contest/1582/submission/132875189. Now I understand if this doesn't get approved and I receive punishment, but I'd like to argue that this is a notorious coincidence. The problem was simple constructive, so the actual solution only consist of a few couts, and our code format seemed to match. However, I figured out the entire solution myself. In fact, in my first submission, I got wrong answer on the second pre-test. I then realized that in my code I forgot to consider when a[1] == a[2], which I fixed in the next submission (one that triggered the anti-cheat). Moreover, I believe that our coding styles are different, with completely different templates. Lastly, if you look at my comment, I described my approach right under my solve() function, starting from the first submission to that problem. Again, I hope that I do get cleared. However, I do understand that this may be inconclusive evidence. Anyways, thanks in advance!
Edit: I also don't know zglicz in anyway online or in person.
Edit 2: The time interval at which I submitted my solutions (in UTC-4), would not have allowed me time to cheat, as it is only 7 minute between my C solve and first submission on D, and 6 minute between my submission which WA pretest 2 and the accepted solution.
After the round 750, I received the message:
" Your solution 132867227 for the problem 1582C significantly coincides with solutions vpike/132864849, RefreshedCoder/132867227 "
The two solutions can be found here:
132867227 132864849
It's a wrong judgement. I personally don't know vpike and it's just a coincidence that our solutions are similar in this simple problem. I solved in total 6 problems in the round and there's no motivation for me to cheat on problem C.
Please, could anybody help me to get my rating back?

hi, i am new to codeforces and i have used two accounts to submit solution and i got this warning also.So i want to know that after writting my reason in comment will i get my rating back. Thanks
nope
Hi dear , The registration confirms that you:
So We conclude that you did not follow the rules!
I use sublime as my default editor. But during the contest it crushed. So I used idone.com to run my code. I didn't knew that my code can be seen by others. This was a mistake. I assure that this wont happen again.
MikeMirzayanov I wrote my code myself in Educational Codeforces Round 116 (Rated for Div. 2). Please, change my raiting! System
My solution Riankk/134106000 is matching with kush_1312/134115092. But I haven't contacted anyone during the contest. Also, the codes are not very similar. I think the similarity is just a coincidence, Can I get my score back.
You have the same solutions for two problems!
Round 753 div3 D Extremely sorry sir but it was a coincidence, this is the first time I got this warning. I have not cheated. I didn't notice that my ideone submission was public. I will remember it in the future and never repeat the same mistake. Please consider it for this time. I also noticed recently that my code is not exact similar from them although the approach is. Almost the same approach is also shown in tutorial. I request you not to skip the submission.
I have meet the same issue with you. I just read the tutorial, and I found that the tutorial is almost the same with my solution. I think that the problem D is so easy that the coincidence is unavoidable. I hope my contest wll not be skipped : (
https://codeforces.net/blog/entry/96941
I just meet this issue, and my contest is skipped. I think the problem D is so simple that such a coincidence is unavoidable.
Can anyone please help me with my issue?
Hi Admin. Today i had some issues with my compiler so amid the rush i immediately switched from my local environment to ideone.com. I don't know why i got two messages from the system for my accepted submission in the Codeforces 757 Div2 Round that my solution coincides with someone. I got a warning too. From now I'll take this seriously that if i am coding in ideone then I'll make sure to turn the visibility to private. Its a sincere request from my side not to deduct my rating or block my account. I'll take proper care from the next time that whatever code i write is completely private Please return back my accepted submissions in the contest as I strived really hard for the problems and revive the rating. Thank You.
There's some error on my computer, which caused the repetition problem. I'm sorry.
https://codeforces.net/blog/entry/97309
During that contest, I remember using ideone.com for my vs code suddenly went slow. I used ideone.com in the last contest either...won't use it public now on.
Dear staff, I really don't understand why my code was checked again. You can check my historical submission record of problem 1609E, [submission 137265393].It was 2:21 when i solved this problem, and the rechecking of the other party to submit code time significantly later than me, I am because of worry about some details, so I resubmit my code, I don't know why the two code is so similar, but it's clear that even with the copied behavior is also the other copy to me.I hope you can review the code of this game and give me a reply,thank u.
Please return back my accepted submissions in the contest as I strived really hard for the problems and revive the rating. thank you

Hello MikeMirzayanov!
On September Fifth, I participated in the Codeforces Round 742 (Div. 2). And my classmate JackF participated in the contest, too. I couldn't solve the problem F but he solve it. So I secretly copied the code to my computer while he was away, and then submitted it after changing a small part.
This is his submission and this is my submission.
I admit that I cheated in the contest and stole his code, causing his account to be blocked by mistake. I realized that my behavior was wrong and did not follow the rule of the contest, so I am very guilty and sorry. I was wrong, but he was innocent. Can you unblock his account JackF?
Thanks!
MikeMirzayanov, I've written in September, but you didn't reply. Could you give me a reply today?

MikeMirzayanov
hey guys I have 2 accounts LEGENDVISHAL01 and LEGENDVISHAL07. I participated with both accounts in the contest so my submissions are same in both. Can anyone tell is it legal to participate with both accounts in same contest. I will stop doing that if that is true.
ofc its not lol
imagine tourist getting 10 accounts on top 10 and reaping everyone's rating
okay bro sorry for that, i'll keep that in mind next time.
i'll bring single account in 1 contest. is that fine.
having 2 accounts is legal or not?
also not legal but they dont enforce it (because its basically impossible to 100% prove that some account is an alt)
It will be really great if you check this case manually. I think the matching is mainly because the other guy uses my template.

Hey MikeMirzayanov,
Recently I received a message from codeforces that my solution 139303414 for the problem 1618D significantly coincides with solutions KaranBardhan/139262858. The similarities are obvious in the two submissions but that's just a coincidence.
The coincidence cannot be proven, but I would like to present some points that why i won't cheat.
This was a Div3 contest so it wasn't rated for me, I just came to checkout the problems with half hour remaining.
The problem was pretty simple for me according to my rating and so was the code, so having a coincidence like this is pretty much possible.
I have participated in 100+ rated contests and never have been ever accused of plagiarism before.
Thank you for your time please review my request.
My solution 139490794 for the problem 1617A coincidentally conincides singhutkarshh/139500950.
This is clearly a coincidence because my solution passed all testing whereas 139500950 failed on test cases,
Please look into this.
.
?
My submission 140076717 for the problem 1619D - New Year's Problem is being considered same as akshaykumar99's submission 140068227. As a result, I have been ruled out of the contest Codeforces Round 762 (Div. 3).
My code is clearly different from his. I think it was a pretty obvious binary search problem and there can be two users who can coincidently implement it the same way. Although, it does not affect my rating, marking my submission as Skipped does not leave a good impression on my profile.
I would request the headquarters, MikeMirzayanov to please have a look into this.
Also, If one tries to compare, a lot of differences become visible in the binary search part. The condition for while loop, mid value, updates in l and r, all are different.
I have not used any public platform to code my solution as well.
I used ideone.com in order to write my code in public mode and someone copied my code This was a mistake that wont be repeated in future.I want my rank PLS.
I was using an online third-party ideone.com for writing my code That's why I got plagiarism. I will take care of it in the future.
I would request the headquarters, MikeMirzayanov to please have a look into this.
Dear MikeMirzayanov,
In Codeforces Global Round 18, I was judged to be cheating.Here is my explanation.
The Problem H of Codeforces Global Round 18 is a standard task of isotonic regression algorithm as well as this algoritem is well-known in China.
And my code is copied from this link:https://www.luogu.com.cn/blog/Hakurei-Reimu/solution-p6621. And I changed the cost value part and delete the liner-base part.
I think it is in line with the rules. It shouldn't be treated as cheating.
Regards, KAAM
Hi. I'll investigate it tomorrow.
Excuse me, it's Thursday today, when will you investigate?
Hi I am avinash204, and I received a message today that someone has copied my code and it has resulted in getting a penalty ,however, I have no clue how someone else has the same code like me as I wrote it all by myself. What about my ratings will I get it or not?
Today I received the following message -

Dear MikeMirzayanov, Problem C is a pretty simple binary search problem. There isn't really much to code in the problem and that's why the two solutions 140907946 and 140909200 look almost similar but I assure you this is just a coincidence. One can see there are differences in the code here and there and also the template is totally different (Though I know this doesn't prove much). This is the first time I got accused of cheating :/ and although, it does not affect my rating, marking my submission as Skipped does not leave a good impression on my profile. Can you kindly look into it?
Thanks.
Dear MikeMirzayanov, please consider this request. I am totally honest with this. I have participated in 42 contests so far without a single accusation of plagiarism. I sincerely hope you will consider this.
Today, I received a message saying that my solution 141039664 for the problem 1616A significantly coincides with the solution 9thcalamity/141076836.
I believe that this was a very easy implementation problem and it is completely coincidental for two such short and natural solutions to be the similar to the extent they are. Moreover, I have submitted my solution way earlier than the other one (even within 2 minutes from the start of the contest) so there is no way I have copied from anywhere and I don't even know this user 9thcalamity so there is no way (and even no logical reason) that I have provided my code to him/her. I am well aware of the rules and haven't used any online IDE like Ideone.
I believe that this is just a case of coincidence that cannot be well-defined for such an easy problem. I would request MikeMirzayanov to kindly look into this case and revert my skipped solutions back (although I would have got a heavy negative delta in the round).
Edit: Some more details — The user 9thcalamity with whom my solution is coinciding has also submitted 2 Wrong Answer attempts for the same problem which look similar to his coinciding solution. This shows that he has solved the problem on his own otherwise those penalty attempts would not have been there. Moreover, this user seems to be Russian (from his submissions to Russian problems) and I am an Indian. So, there is no way that I know this user.

I have participated in yesterday's 764 div 3 and was able to solve 3 problems. But don't know what wrong happened and plagiarism occurs in Ques 3. Frankly, I was not able to solve that question so I go through Google and find an article end I get the logic from there and I implement that in C++ I don't know if the other user goes through the same link may be so please consider this as it is my first time I assure you that this will not happen again so please don't deduct my rating.
Both the codes are word to word same, and such "not so short" codes are very less likely to match 100% with the other ones, moreover you should link the article from where you got the logic as it might help you if you're innocent!
Hi, today I received a message saying that my submission 142233988 was too closely related to submission 142240970 from CoNKeR_04 in problem 1624G - MinOr Tree.
I did not copy someone else's code, in fact:
Also, I don't use online IDEs, I use Vim instead.
Although the contest is unrated for me I ask you guys to remove the cheating accusation. It is the first time I receive a warning but it would be pretty sad if I lost my account for something I didn't do.
Thanks in advance
MikeMirzayanov
I use the code written by team competition. Because my document collaborator has not been in contact with the algorithm competition, I can rest assured to use it. I used it like this before, but I'm sorry for the problem this time. I'll use DEV-C to write the code in the future to ensure that there will be no code leakage.
The three of us are from the same school and use the same set of algorithm templates. I'm sorry for this. I'll deeply reflect on myself
I'm sorry. The other two are my ACM teammates. We use the school algorithm template in the same way, because I am not good at English. Not reading the rules carefully. If I break the rules, I am willing to accept the deduction of points.The above from the webpage translation, hope many forgive
Hey codeforces,my solution LeBron23/143668172 coincides with the submission of 20je0011/143699503 because during the round i pasted the code on a chating app instead of submitting it.The mistake was identified by me seconds later and corrected later but the recipient of the code pasted the similar code .So i please request you to please grant me a single chance as this was a one time mistake.You can see that i used the same template and coding style for the previous submission whereas the other person clearly have copied me.I have messaged the person(20je0011) and he is willing to admit it.Therefore pls forgive me for this mistake.I will not repeat the same.
.
I got a message from codeforces saying that my code matched with another contestant. These are the links to the submissions: mine spartan24 I have tested my code on my local ide and I haven't tested it on ideone. The codes are pretty much lookalike but I haven't copied. Furthermore, there is only a 7 second difference between both submissions, which justifies my claim. Thanks.

I just want to clarify that in this problem I used a function from a geeksforgeeks article (linked below) because I didnt had enough time to write it myself. As this article was published way before the contest, I urge the admin MikeMirzayanov to kidly remove the charge of plaigrism and restore my original rating. ****
Link of the gfg article
function i used,
int findMin(vector &arr, int n) {
// Calculate sum of all elements int sum = 0; for (int i = 0; i < n; i++) sum += arr[i]; // Create an array to store results of subproblems bool dp[n + 1][sum + 1]; // Initialize first column as true. 0 sum is possible // with all elements. for (int i = 0; i <= n; i++) dp[i][0] = true; // Initialize top row, except dp[0][0], as false. With // 0 elements, no other sum except 0 is possible for (int i = 1; i <= sum; i++) dp[0][i] = false; // Fill the partition table in bottom up manner for (int i = 1; i <= n; i++) { for (int j = 1; j <= sum; j++) { // If i'th element is excluded dp[i][j] = dp[i - 1][j]; // If i'th element is included if (arr[i - 1] <= j) dp[i][j] |= dp[i - 1][j - arr[i - 1]]; } } // Initialize difference of two sums. int diff = INT_MAX; // Find the largest j such that dp[n][j] // is true where j loops from sum/2 t0 0 for (int j = sum / 2; j >= 0; j--) { // Find the if (dp[n][j] == true) { diff = sum - 2 * j; break; } } return diff;}
ThankYou.
Hello.In Codeforces Global Round 19 Problem D,I can't believe I wrote almost the same code with 1443356159 when I saw the message informing that I am cheating!It's just a coincidence.
Problem D is just a typical easy problems,only need to use knapsack algorithm.knapsack algorithm only has few ways to implement.Here are some similar solutions.(actually the basic logic is completely same)
https://codeforces.net/contest/1637/submission/146103482 https://codeforces.net/contest/1637/submission/146108857 https://codeforces.net/contest/1637/submission/146108958
In such great amount of similar solutions,it isn't a small probability event to have the same code.
Also,in 1443356159's profile,you can see that he/she is in Mianyang and I am in Hangzhou which is far from Mianyang(several provinces between them) and I didn't know this person before.And all of code is produced by myself in the contest,I didn't copy any code from any third party source(of course without the includes).
The time between the two submissions was only 7 minutes apart,there was no time to change the sytle of the code and it's stupid to have the same code without changing anywhere.
I didn't copy anyone's code,please change the rating back!Thank you in advance!

Although it's just +33 rating changing,I feel not good when I am accused of doing something I didn't do.
MikeMirzayanov
I am wondering why MikeMirzayanov didn't decrease your rating because this is the second time you are doing such !
In the first contest,I didn't know it will break the rule.I use my other account to submit code.But from then on,I hasn't break any rules.And this time,I even didn't know this person!If you compare my submisson with his submisson in other problem in global round 19,You will absolutely find that I am not cheating.
We both solved A,B,C,D,E,F and why I need to copy an easy problem's code?
I'm not going to reconsider the verdict on this incident. You've violated the rules multiple times before. The codes are actually very similar.
More than once the contestants has the same code but completed independently. Like this
I wonder why people bother necroposting here, has anyone ever got their rating back after requesting here?
Hello Everyone, today I got a message from system that my submission https://codeforces.net/contest/1644/submission/147328513 during the Educational Codeforces Round 123, has been found similar to other code from user name "wubwub" and and my account may get blocked due to this. i didn't cheat or submit my code on another account my solution was written by me and i saw a lot of my friends with the same code and they didn't have a problem
the solution is basic dp on best sum for len k i swear i didn't cheat or something there must be a coincidence
anybody can help me please ?
MikeMirzayanov @MikeMirzayanov
I used two accounts in Codeforces Round #773 (Div. 2) to compete and submitted duplicate codes, which was my mistake
Hi MikeMirzayanov, I DM'ed you the following messages, but due to non-reponses, posting them here for greater chance.
I own the handle utkarsh995 and all its submissions. But it seems the attached email address has been changed from [email protected], which I own. I can't login via my email and resetting password using handle, I do not get the reset mail. Please help. I created this temp account to get help. I have a session of above account open in one of my devices. I see the email has been changed to [email protected], which seems fake. I can't revert it back to [email protected] as the password has been changed. It seems my account has been hacked. Someone even participated in contest 1632 and submitted all copied codes and I got a violation. It's embarrasing for me to justify this but, as you can check, I do not use the template used for any of my solutions. I was inactive for some time and anyway did not check messages, and suffered due to it. Again, please help. Regards Utkarsh

The system told me that I cheated because of my Problem G solution in Round #776 coinciding with others. However, this problem had a same version on http://poj.org/problem?id=3463 ,and I had finished the problem with the help of a blog https://www.cnblogs.com/xingxing1024/p/5224363.html which was posted in 2016.So I use the code to finish problem G.Is it illegal?
MikeMirzayanov
It's a 200 rating change so I am upset, could you please give my rating back? I have never been cheating in my account and I definitely hate the cheaters. I don't know if my behavior is illegal.
What can I do to let Mr.MikeMirzayanov reply me?
The solution coinciding with my solution is purely a coincidence. It has happened with me in Codeforces Round #776(Div. 3). My solution was 148903720 for the problem 1650C. I developed the logic on my own and I don't know how another people's solutions was matched with my solution. I used vector, pair and map in my solution. Firstly, I made a vector of pairs and using a for loop to insert a pair in the vector and I sorted the vector . And then using for loop from 0 to 2*n I got a sum of first elements of the pair that is coordinates and Made another vector and pushed second element of the pair to that vector. And then sorted that vector and printed the sum. And using a for loop and the map that I made first and printed the required ans. Please verify it and update my rating.
I was accused of cheating, and after i have checked ADO/146139752, ChtotoSlabovato/146145769, 9_shuriken/146152539 i realised that the only thing we have in common is partition function which was found by me on the internet by link https://www.geeksforgeeks.org/partition-a-set-into-two-subsets-such-that-the-difference-of-subset-sums-is-minimum/. I was only copypasting from geekforgeeks, not from other contestants MikeMirzayanov, help please

Its just an coincidence, problem C was an easy problem where the approach was very common and similar. Also for a simple problem with the same approach, these many people including me got an similar solution. Kindly lift the penalties from me as I have solved the problem myself without anyone's help and sharing my solution. MikeMirzayanov Kindly lift penalties from my account.

Also I did not use ideone or any other online compiler.
Since I was using a public computer for giving the contest I accidentally submitted the solution through a different account(that was already logged in ). Upon realising my mistake I tried to resubmit the solution from my profile and that caused my code to get plagiarised.

I did my code by my own, in my own computer, I didn't public it anywhere in the Internet, I also checked DELTARUNE profile, and he/she's in Korea and I'm in Australia and I don't even know him. My submission just came after his submission 14 secs. We (me and DELTARUNE) have expert and CM. At our levels, I pretty sure that we can solve A Div 2 by ourselves. This A div 2 has very easy solution, I think we just unfortunate came up with same idea (it's also similar with editorial and I also believe that there are a lot of participants also had same idea as us) and same coding style.
Please reconsider MikeMirzayanov, I didn't cheat or do anything like that. Thank you!
I agree with zettt's comment.
First, I wrote this code by myself, in my personal computer. It's impossible for other people to access my code.
Second, it's not written on his profile, but according to his comment, zettt lives in Australia while I live in Korea. We don't know each other at all.
Third, considering that me and zettt is CM and Expert, I think we can solve div2A easily. I think it's just a coincidence that occurred because we came up with the same idea and had the similar coding style. In addition, div2A in this contest was very easy problem, so many people except us also used same idea.
I'm little embarrassed that such a coincidence has occured. Please reconsider your decision, MikeMirzayanov. Thank you.

i didn't cheat and i don't know both of Aksnov and skhan_org,the reason of coincide is class FastIo in our codes ,most of python programmers uses this class for fast input ,this class take half of problem code ,secondly how also this coinside happen ,the variables is very different and all of ours uses different way for print the solution .
so please MikeMirzayanov return our solutions ??
Your solution 151551197 for the problem 1660C significantly coincides with solutions khnhcodingkarlo/151551197, chungqt/151586274, tahuruzzoha/151586666. I received the above mail this morning. With all due respect sir, I have just started with codeforces and use VS Code to write my own logic and codes, the above allegation to me cannot be justified, I have no clue how my code got out and how did this happen. The first said user 'chungqt' is not even available as a user when I search him on codeforces. As for the second said user 'tahuruzzoha', his solution can be found to have a timestamp of exactly 10:15 pm (IST), the exact time when the contest was ending, whereas my coded solution has a timestamp of 8:53, more than an hour before this user submitted the solution. (Doesn't this seem a bit suspicious why his code was given at the last minute?). My further question stands, if this solution had been leaked publically, (as we know some get out to all public freely or for some money), there would have been not just 2 but 20 same submissions more or else. To further support my case, I even did some comments in my code, and used a set instead of a map because just that morning I had learned that even finding a elements in a set O(logN), which struck me to use it in my code. After the contest I realized that a map would have worked just fine, or even better time complexity wise. If I had cheated, wouldn't I have used a map or same logics and all? There is so much difference between my logic and other 50 codes I have seen past hour now. I don't know how to prove my innocence any further in this case, this has never happened to me, and I don't know what is going to happen next to my id. If anyone wishes to shed some light on this, please help. I seriously have no clue how my code got out. :( That too to just one guy? I don't even know him :( Please help.
My submission of Round #782 is skipped, but I didn't copy code.
The system message said my submission of problem A coincide with user codestian.
My submission for A:153905601
User codestian's submission for A:153892004
I came up with the solution of my own, though the logic are alike. The strong evidence is my several previous WA submissions, Everyone can take a look, see I was trying to solve this problem of my own way during the first 30 minutes till it got accepted. My solution to A is coherent.
See my several WA submissions: 153895274 153904887 153905601
You can also check all my submissions of contest #782, especially my approach of problem D 153924819 differs from most AC submissions. It all from my own, clearly not the Internet. Also my solving order A -> D -> C -> B, the timeline during the participation in this round and my code style from my earlier rounds can tell that I am being wrongfully accused.
All these can show that I did the contest honestly.
Seems the misunderstanding occurred because of the first problem is easy, and many solutions are short, thus coincidence happened.
I am not a cheater.

About skipping my solutions in Educational Codeforces Round 126 (Rated for Div. 2)
I used the code from the github page of the Jo3kerR github link to the code
My submission
Jo3kerR's submission
MikeMirzayanov Please look into it, thank you.
As you can see, only the template of the segment tree is matching. There is just one more thing, in the
updatefunction I added two more variables that were not present in the Github repo, one for first term of the AP, namedfirst_term, and one for the common difference namedcmn_diffand coincidentally, noomaK also named these variables exactly the same. Apart from these everything is in the Github repo.MikeMirzayanov please revert back the skipped submissions.
Hello,
MikeMirzayanov,mesanu,SlavicG,Errichto In last Div.4 contest Codeforces Round 784 (Div. 4) I got Plagiarism on my F problem, I am sure this kind of plagiarism detected due to straight logic question. so this is a coincidence.
I wrote code on my own and as you can see that in this submission 154392853 I got TLE on my submission and then I changed my code a little bit like this 154393751 and this one was accepted because of binary search has less time complexity. please check out this and give my rating back and also I also solved out H problem after a contest. So please look out at this and give my rating back.
Any updates on it MikeMirzayanov sir.
I have just received a mail from codeforces that I have been plaggerized in codeforces round 784(DIV4) .
And the mail content is : Your solution 154335204 for the problem 1669C significantly coincides with solutions sanchitjain336/154333343, sanchitjain336/154335204. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
Man, I am the sanchitjain336 only , have submitted the same solution 2 times because of a network issue their system is not accepting my first solution, and its there in the queue for almost 3-4 minutes. How can i get plagiarized from one of my solutions only, this is ridiculous, My whole effort to increase rank in the contest goes to vain .
Is there any way to get in touch with codeforces team for the same? Pls reply

I submitted the same solution twice due to queue and network issues. As you can see both the submission are from my account submitted just after one another. Please look into the matter as I am completely innocent in this case. Please revert back the rating change asap as this incident is really disheartening for me. MikeMirzayanov
Hi Codeforces, I got a message saying that "Your solution 154564625 for the problem 1671D significantly coincides with solutions LittleOrange666/154529195, Rosalie/154564625." And I found that my solution got skipped.
I swear that I did solve this problem totally on my own and didn't refer to any other resources. It's not a hard problem. Following my thought on this problem, there's only one way of coding. Thus it's of high probability to have a similar code. It's a coincidence that this guy and I had a similar coding style and I totally don't know him. Is there any chance that I could get my ranks back?

I am using ideone for a long time. but it had happened to me for first time. i don't know about that setting. i will assure codeforces that it will not occur again in future.

Alright so this afternoon, I received a mail informing me regarding my solution being coinciding with some other ID. It is hereby to be informed that both the IDs having the same solution is mine named- saragupta0302/155998521 and sara03/155998623 and hence the solution. Also, I don't find anything wrong in submitting solutions from 2 IDs, I hereby request the admin to look over and take the necessary steps to consider my submissions. Thank you, waiting for a positive reply.
Here is what is wrong with 2 IDs, you can avoid the WRONG ANSWER penalty from one account.
I wrote the following blog to justify my case. https://codeforces.net/blog/entry/102562
Apologies for the same as I don't happen to write contests frequently.

It was just a coincidence that the solutions are similar. It was a fairly straightforward solution so coincidence like this are bound to happen. I had used an offline compiler so no chance of leaking my code. Anyway, the contest was not rated for me but I wanted to clarify that it was a coincidence.
I received a message saying my Iftekhar_Hakim_K/158043224 matches with Mr_Emrul/158040050. That is clear coincidence. Kindly check the problem statement which has pretty straight-forward idea and many people should have similar implementation. In fact, my submission 158043224 matches with editorial's implementation. You can check my WA solutions too. MikeMirzayanov
MikeMirzayanov Have you checked?
I received a message saying "Your solution 158011430 for the problem 1682B significantly coincides with solutions Roll_Num_56/158011430, akash_iitr002/158041337." It was a simple problem. Many people did the same implementation. Kindly check manually MikeMirzayanov
I received a message "Your solution 158182772 for the problem 1681C significantly coincides with solutions BhavyaSolanki_9/158177050, SoluckyBhavya9/158182772". This was a simple implementation problem and problem statement was hint itself. many people has used selection sort for implementation.
both are your accounts, stop cheating
MikeMirzayanov awoo submission 158171922 and submission 158186561 are nearly same and its a pure co-incidence neither i know the person nor i used any online IDE and question was pretty brute force so its obvious to have same kind of solution and further more I have no history of such offence and i personally hate cheaters . This kind of things demotivates a lot please look into the matter.
MikeMirzayanov the person with whom my A and B solution coincides of last Educational Round Divyanshu1593 has given the contest but i think either the concepts are similar or he was in my room (which is a serious issue to be looked after). Because python codes can be written in short way solution is coinciding. This is my second time happening this. Please consider all the situations before sending a cheating mail.
Today I received a message from the system: Attention!
Your solution 158186561 for the problem 1681C significantly coincides with solutions Dablu_saha/158171922, rkrohit/158186561. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked. MikeMirzayanov sir, neither I cheated the code of anybody nor I used any online IDE. It is coincidence that my solution:158186561 and Dablu_saha solution:158171922 are similar. Since, the question was normal and a lot of people solved it so it is obvious that the thought process/code of many people are similar. So, I kindly request you to consider my submission and give rating according to my rank.
Thanks
I have received message saying my code coincided with some consistent123's solution for problem B of div2 #793 contest .All my solutions are showing skipped now,but I really don't even know who that other person is.The solution for problem B was so obvious sir that it's just a mere coincidence that my writing style and his writing style matched,please have a look into it..The problem B was so naive that you will find thousands of code with the same solution .please consider
MikeMirzayanov I have already commented here, but yet to get a reply for 10+ days. That's quite disheartening, for a problem where you only need to count frequency of input values, which directly matches with editorial's implementation, that too for a contest which was already unrated for me.
Only non-cheaters can like this comment ;)
But only cheaters will fall for it
[user:MikeMirzayanov]Yesterday I switched my IDE from vscode to ideone due to the glicthes in my vscode and I didn't know about the default settings of ideone due to which I used this IDE in public mode and my code get copied by someone else in [contest:797] that question was really easy I did that by myself. MikeMirzayanov I request you to please give back my ratings.

I don't even know who they are. I didn't use any online compiler or I didn't take any code from the internet. All the codes are completely written by me. And I use my own template. I have no idea why this has happened to me. This is very disappointing and I am loosing self confidence and hope. Please don't do this to me. give my ratings back.
I have the same problem.I guess someone in your room sent your code to another people.
I'm sorry, I think it's a coincidence, I wrote this very similar title and I put the code on my blog

I don't know why my solution is collided with Rohit_a9887/160116355 , but I can assure you that I haven't copied the code from anywhere. I guess this is happened because the same boiler plate of the code I will definitely try to change my boiler plate from next time. Please give my ratings back.
"Boilerplate" means every line of the code? Especially the matching variable declaration that is indented in both codes for no reason.

I would request MikeMirzayanov to look into this and revert my rating back as clearly there is no fault of mine.
Core of the solution is exactly the same...
Yes , beacause it is just a simple swapping problem, and look at my submission time , it is simple coincidence.

MikeMirzayanov I urge you to look into these submissions. I have no idea if/how my submissions are leaked. I haven't used ideone either. Please note that the time of my submission precedes every other, so clearly I'm not the perpetrator.
Please provide an update. Thanks!
Hello, I'm sure that I have not disclosed my code in any platform social software. I guess someone in my room gave my code to another people. His operation is as follows: 1 Submit a correct code, 2 Lock the code, try to hack my code, and copy my code, 3 Give my code to someone else. The evidence is that my code was submitted at 13:04:15. The other three were: 13:51:44, 13:49:51 and 14:04:37. I think this is an extremely wrong mechanism. Of course, this is just a guess, but I really didn't send my code to anyone, nor did I use any code compilation platform. Please do not punish my account. Thank you.
Hello. I have received the same warning. My solution was sent 30 minutes earlier than the one that is a copy of mine. Who should i adress to about this issue? Ty.
I don't know. I'm angry.
Sorry, but it was completely a coincidence .. I published my code on ideone.com that's why the problem has occured. I’m a new member of codeforces. I admit I will never have this behavior. Please give my ratings back. Thank you!
Hi
Codeforces Global Round 21:
My solution(161735764) for the problem A coincides with the cjxm's solution(161733111) due to similar coding style, so my submissions got skipped.
Please have a look and thanks in advance!
Common, it is not about similar codes, they are completely equal. And what about 161752370 and 161750010?
Sir can you please give my ratings back. Actually I used ideome.com becuase of the large input test case, my VS Code couldn't handle it properly. So I used an online compiler. I have been practicing codeforces on a regular and its more than a month I have been this consistent. This is the first time I am facing such situation. Hope you look into this matter.
In A and B, you used long long but in C you used ll. Why this inconsistency in coding style?
Very sorry sir, I try to be consistent but sometimes I use long long instead of ll or vice-versa. You can go through my submissions in my previous contests and the problems solved by me. I promise to maintain consistency in my coding style from now on. I am actually new to this boilerplate code. I copied this boilerplate code from https://www.geeksforgeeks.org/how-to-setup-competitive-programming-in-visual-studio-code-for-c/. So I am not properly used to the new setup. Hope it helps sir. Thank you for your understanding.
your C solution literally looks similar to other solution.Just changing the variable name to your id name does not save u from plagirism
Oh, thanks for the response. I've learnt a lot of "c++ coding tricks" from jiangly's codes, so I think that's the reason.
MikeMirzayanov Why my appeal is not being reviewed? I have already commented twice in this post for it (here and here) . 1 month passed, but I did not receive your reply at all.
Hey codeforces ,my solution LeBron23/162099867 coincides with the submission of blaster777/162104729 because during the round i pasted the code on a chatting app instead of submitting it.The mistake was identified by me seconds later and corrected later but the recipient of the code pasted the similar code .So i please request you to please grant me a single chance as this was a one time mistake.You can see that i used the same template and coding style for the previous submission whereas the other person clearly have copied me.I have messaged the person(blaster777) and he is willing to admit it.Therefore pls forgive me for this mistake.I will not repeat the same.
I did not cheat ah, the E problem is the staining method to determine the dichotomous diagram, in a site called acwing algorithm internal related templates and topics, I learned the relevant templates on it, and the site is a mainstream site for Chinese domestic students to learn algorithms, learning inside the template will have a lot of people, so I did not cheat The website related to the topic and the template related to the website. https://www.acwing.com/activity/content/code/content/48778/ https://www.acwing.com/blog/content/5444/ https://www.acwing.com/blog/content/3816/

Hello today i recieved a mail as
Your solution 163927668 for the problem 1703F significantly coincides with solutions shrutisingh/163922697, rajbunsha/163927668, anand92050/163932238. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

In case of repeated violations, your account may be blocked.
I did check there answers after mail but it seems to have been quite coincidental due to question being too trivial and method implemented is a standard one.
There is no way i can think of that can't be coincidental much of it resembles my programming pattern and if this is the way there are going to be strikes then uncertainly i may want to leave the platform. name of variables are highly based upon the variable. Please give my rating back or atleast some convincing reason on why there can't be such a coincidence
To MikeMirzayanov:
I received an unexpected message about coincidence of submitted code: "Your solution 164269158 for the problem 1705A significantly coincides with solutions fanfly/164269158, kennyleet/164274581."
Since I wrote the code offline (not using any online editor) and did not share any piece of code to anyone (during/after the contest), I'm sure that coincidence is not due to any kind of plagiarism.
However, since the code submitted by me was not based on any website and was completely written by myself, I cannot provide any reliable proof except for the source code saved on my laptop.
Is there anything I can do to disprove the possibility of plagiarism?
Hello, I recently received a message "Your solution 164481686 for the problem 1708B significantly coincides with solutions _joKer_0/164481686, anantdwivedi912/164526189".
I literally don't know how he got my code. I code on my personal laptop, I've even made my GitHub repository local. Seriously man, pls consider my request. I'm suspicious that I don't get banned. You can even compare the submission time. This dude, didn't even care to change the variables, or the template even. Only the part where I write my own info is not copied by him(a real smart gesture). (Previously, submitted in russian)

We are workmates/friends who work together on upsolving problems with the same template which can be found publically at https://github.com/sammochen/cp/blob/master/main.cpp. This template is publically available with a last commit 12 days ago, although in reality has been online for many months. Both submissions were written independently on local vscode.
I don't konw what happend? Why attention me and cancel my last two contest???????????
Why my rating is rolled back without any message about cheating and I used nothing except Dev-C++ during the contest?
I'm sorry about that. But I'm sure that I wrote my code independently. This solution is common, just follow the problem's meaning to write the code will be right. So my code is similar to others. Please rerate me. Thanks!
Also, the three of us studied algorithms together last month, and we did a similar problem. https://www.luogu.com.cn/problem/P5488, one of the small problems with the game of this subject is very similar.
I hope the administrators will rerate that. Thanks.

it's so pity that this happened.I think it's a very coincidental thing, because All the data structures I know are questions with templates. Obviously, this question (D. Rorororobot) is also a template question of data structures. I think it is normal to have the same code, because I learned data structures online, and many people will inevitably have the same ideas and codes in the competition.We learn to solve the same template problem on an open site that can be found publicly at https://www.acwing.com/about/. Please give my ratings back.
It is not about same data structures/template code. Your solutions are same.
Hello Dear Administrator My D question was completed independently by myself and after I finished I used a different method to complete the question myself Please restore my rank
Your code and errormakers's are the same. Just don't do it again.
Really? But I don't even know this person
Can't I get my rank score back?
From the time of submission I submitted it first and I don't know this person personally so I don't admit that I have leaked the code so please don't skip it
We are probably using the same code template But I can prove that I did it on my own
Hey it was my mistake in educational round 132 that I by mistake used 2 IDs as I have decided to work with new I'd but in between as I was in incognito and i middle my browser shut down and when I open I just submit the problem on this CF I'd so I request you to please give my ratings back if I somehow can show you that two accounts belongs to me pls tell
I get a message
Your solution 165186328 for the problem 1709C significantly coincides with solutions Hanghang007/165186328, AAAmazing/165208537. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation.
First of all, I'm sorry.
But, I filed before him and I don't know about the other guy, I don't even know who he is, it's not my problem.
I wish I could be excused from punishment.
Hello MikeMirzayanov, My solutions for Educational Codeforces Round 132 (Rated for Div. 2) has been Skipped due the coincides with solutions El_king00,the two accounts are mine (this account and El_king00) i don't know if that thing is a violation of the rules or not but these solutions are made by me (implemented and submitted by me )the only difference that i added my name at the beginning of the solution submitted in this account
i didn't cheat or copied someone else's code , Your solution 165168953 for the problem 1709B significantly coincides with solutions El_king00/165168729, Mostafa__Fouad/165168953.
You cannot submit in the contest using 2 different accounts, that’s a violation
Appeal of Educational Codeforces Round 132
Dear Sir or Madam， We got a message from the system after “Educational Codeforces Round 132”：
“If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. ”
So we followed the message to appeal. In fact, we did problem C last year and I did problem D this week coincidentally (The only difference of them is the way of input and output). That is why both of our code is similar to so many others. Some of them I don’t know before, they might have done the same problem before. Some of them are my friends, we have done these two problems together, and some of the code we use is the template we decided on together.
The rules in http://codeforces.net/blog/entry/8790 said this is allowed:
“Solutions and test generators can only use source code completely written by you, with the following two exceptions: 1.the code was written and published/distributed before the start of the round, 2.the code is generated using tools that were written and published/distributed before the start of the round.”
Here are the evidences. They all wrote before the contest 132! (If you need more evidence to judge, please contact me):
C: http://acm.hdu.edu.cn/showproblem.php?pid=4915（where we find C first）
http://t.csdn.cn/5qwDN（where we learn C first）
D: https://www.acwing.com/file_system/file/content/whole/index/content/6131167/ （the templates that we wrote and published）
We apologize for the extra work this has caused. But we did not break any rules. The same problems are what none of us want to see. Please correctly judge this special case and cancel the wrong punishment for us. We also want to know what to do next time we encounter the same situation. This is not the first time we meet the same problems in codeforces contest that we have done before. Since we are teammate, we need to make our code style same, use the same template, and work on the problem together (not in contest, when we learn). It always leads to the probability of being punished by mistake when we meet the same problem we have done before. We have already done the problem coincidentally before the contest, spending lots of time to learn how it work, But we still have to spend a lot of time modify code in contest to avoid being punished for mistakes. That sounds very unreasonable! Please judge correctly. Withdraw our wrongful punishment. And tell as what to do next time we meet such a situation. (We also don’t like this situation!). If there is anything else we can do for you, please let us know. Yours, AINgray and DeepLearning-
I I just put my code to my other account first to check the correctness to decide whether to participate in this game or not to participate.
And I am sorry I am not gonna do it again I know the rules now.
I received mail for my contest CodeTON Round 2 of plag ...I tried running my code on ideone.com in default setting and someone copied my code and I was not aware about that...,I don't have idea that someone can see my solution on ide during contest, that's why I received a msg that your solution is colloide with others. I will take care from next time

Me and cx330_ L is not consistent. I use KMP and he uses bruteforce. In interval merging, we use the merging method of this article. You can see that my code style is always the same for all the topics in this field. Please restore my place and return my score. I didn't cheat.

I have posted my boilerplate code here! and commit history is earlier than the contest itself.
The main logic inside func() totally differs so please return the ratings to usual.
Sorry Sir , I was not aware of this rule , I am a student and only participate in contest for gaining knowledge and developing skill and no wrong intention. Both of the codeforce ids are my own where I submit the question. I promise you to not repeat this again and requesting to forgive me this time. Please reply.
yes
I failed to realize approximately this ideone.com with the default settings (public get entry to code). This become the default. So it's viable that someone copied my code. Now I set it up. and also my submission time was submitted before that mentioned person. so they can stole my code.
I'm not sure if this was already addressed or not, I posted this message earlier but not to this thread but to the thread of the 814 round.
"Hi, I got a message from the system saying that my solution is similar to that of another user. However, this is because we both use the same template which can be found at https://github.com/JaroPaska/competitive_cpp_17 and was published before the competition."
Kukuricnachrumka also already posted a whole blog post about this. https://codeforces.net/blog/entry/106145
.
Exactly, the logic of adjacent element in 2d matrix was available at stack overflow or infact every good coder knows this optimised trick because it is so common like finding factors of a number. And is it a contestant's fault that the questions of contest has only one logic . the question 'Corners' only has a single logic under that constraints. So,kindly go through this ( https://stackoverflow.com/questions/2035522/get-adjacent-elements-in-a-two-dimensional-array) link once and revert back the ratings of all the sincere participants of the contest.
Also in the question "Interesting Sum " has constraint 10^5 which means it can be done in NLogN time and surprisingly those solutions which was completed using sorting in C++ got accepted but the same for Java everyone got TLE and as far as I know 1 sec=10^8 operations and in the NlogN complexity the maximum number of operations goes to 1660964.04744 operations i.e. 2*10^7 operations..... Is is fair to all java coders ?? Is that their fault to code in java???? So please sir look into this and revert back ratings for the contest. Hope to get ratings back asap. Thanks and regards
hello Codeforces and MikeMirzayanov, I had a message after Educational Codeforces Round 134(Rated for Div. 2) .which says that "Your solution 169872486 for the problem 1721D significantly coincides with solutions Codfish/169872486, haoduoyinliugou_/169877241.

Hello, Dear CodeForces Contest Team, I'm CodeForces user quhaoran.
In the first 2 days of Div.4, I didn't cheat, but I was wrongly judged by the anti-cheat system.
I believe that CodeForces will not easily put a person in the name of cheating, but I did not cheat, I hope the official investigation!
I used ideone.com to write my code in default mode that is public, I have changed and this will never happen again.
hi, MikeMirzayanov.
The submission 171396201 and 171412747 of 1728D - Letter Picking are just coincidences
I am sure I didn't copy the code or send it to others.
Obviously, we have the same idea of this problem, and coincidentally, our code styles are similar.
My submission is at 23:33(UTC+8) and the other one's submission is at 00:09(UTC+8). And this problem is simple for me. This ruled out the possibility that I copied his code.
By the time he submitted his code, I had already came up with the solution to 1728E, so I am sure I can become yellow after this contest. I have no reason to send my code to others and cause me to be skipped.
Moreover, solutions to 1728D are all very similar, except dfs and the O(n) solution. If necessary, I can find more submissions similar to mine.
So I just have the same idea and similar code style with a stranger coincidentally.
Thanks!
Codeforces Round #820 (Div. 3) ques D(1729D) i neither used ideone nor i leaked my code. it was totally a coincidence. and it was a simple question so many other have used same logic and if u r considering arr,brr and crr for the commonness of the whole code, then let me remind u that arr,brr and crr are common variables which are used by everyone and there are many example such as a,b and c are commonly used by many so , please be fair and give me a solution about it thanks
it is my first time to have such an issue. my friend and I was together solving the same problem in the contest simultaneously but it was a coincidence that after writing the code for the same problems to have very similar code so we decided to adjust them to have the same code (for joy sake)but we didn't know that there is a punishment for doing this. so i hope you take my comment as apology and i can have you assured that this will never happen again.@MikeMirzayanov i hope you understand my position and give my rating back

This is my first time receiving such kind of mail. I am pretty sure that I don't know people mentioned in this message and their codes are submitted 1 hour later than mine. I did not copy their work and I am pretty sure that I did not leaked mine as well. I never use online compilers. The solution for this problem consists of a single check and a simple construction algorithm, so I think this is why our submissions are so familiar. I'm pretty sure that I did everything according your rules, so I hope this situation will be fixed soon. Thank you

Hi MikeMirzayanov one of my solution of the last contest got skipped, but I haven't recieved any message from system neither my rating are changed, can you please tell what kind of skip is that and why
zpf666 and I are in the same team. We use a common template to calculate the number of combinations. This template is from jiangly，for example, https://codeforces.net/contest/1717/submission/170603374
Your solution 174107830 for the problem 1738B significantly coincides with solutions XxDantexX/174107830, import_alok_tripathi/174109848.
As you can see, we have been flagged only because he copied my template. It was with my consent. The actual code used in the solve() function is clearly different in both submissions. I request you to recheck manually and unflag both of us.
Mrs.MikeMirzayanov
first at all I didn't take you idiots and I swear that I didn't cheat . and what about this 175013910 ? please forgive me
Shame on you! You just slightly modified the leaked code. Don't take us for idiots.
MikeMirzayanov
I'm sorry, shuger and Shu_gez is my account. That's why the record 175625227 is so similar to the record 175636213. I can give a convincing proof of the ownership of my account, so I apply to restore the scores of my shuger and Shu_gez accounts.

problem E in round #826
The solution to this problem is very simple. Many people write this way. Our code is just coincidentally similar(and in fact not that similar). You misunderstood me, and I didn't cheat. Please review again,thank you very much.
I just read the code of the contestants on the first page of the ranking. Most of the contestants do the same as me. The core code of this method has only two lines. I think it is unreasonable to judge me cheating because of this. Please review again and recover my score. This is very important for me, thank you!
MikeMirzayanov please help!! this has happened to me the second time in last 3 contests please look my solution to problem d of codeforces round 825(div3) it was simple dfs and hence the logic and implementation can match upto that extent , its quite obvious !! can you please look a it and change the rubrik .i just used the pair returning template for simple dfs and used it on my own , and its not even a big amount of match, the match part is purely due to same use of dfs code, and i had my dfs function already build in my template which i copied from some videos please can you change the rubrik for this question as it had simple dfs implementation and hence this much similarity in code is obvious and its not fair for this.its just because of the simplicity of the idea: simple dfs that builds your ans variable here is my code: 175658929 and here is the matching one: 175615664 please help!!! i dont even know this guy its purely due to the simplicity of dfs code and its purely coincidence due to system check which just went through what part is matching and didn't check for anything else. i dont want to loose out my ratings again. i promise to remove all my template and not use anything similar from this time onwards , please consider this for the last time and please dont reduce my ratings.
Your D is exactly the same as leaked solution for it. Just try to solve problems by yourself.
my submissions in the last round had been skipped for just getting accepted on my other account i accidentally closed my browser and when open the site i didn't notice that i submitted from the other accounts you can see i am not have any intention to cheat and you can just skip the other account submission on the problem but please consider regrading the contest for my submissions i did my best in there last round and you will see this is the only code that coincided in the last round and only after one submission.
Oh,sorry,it was my mistake for logining this account and then submitted.Two accounts are all belong to me,but I logan the wrong account for submitting.Sorry,it was my mistake.And I can post a picture to prove these two accounts are all belong to me.

Why did I get this message? I solved them myself and didn't upload my code anywhere else. My rating is over 1400 and it is not rated for Div.4, so there is no reason for me to cheat. Is there any more way I can prove it?
Dear MikeMirzayanov,
Sorry if you've already seen one of my messages (I know you're really busy), but I was wrongfully plagiarism flagged during the Global Round 23, and I've received no formal statement about what would happen in my case.
Here is my concrete evidence: My submission: https://codeforces.net/contest/1746/submission/176378653 Source of my solution: https://oj.uz/submission/592003 Evidence of me accessing the oj.uz submission during contest (my time zone is GMT-7 so 8:47 AM on October 15th was during contest):
Please let me know of any updates. Thank you so much!
I have no idea how my code has fallen under this issue, but i can assure you i have been writing the codes on my own and its just a matter of coincidence if you feel the codes being similar, thank you , i request you to understand that i have been giving the contests honestly.
Sure, it's just a coincidence: 177207542, 177195491. Sarcasm.
I didn't do anything illegal. Why was my last educational round rechecked somehow?
Common, submissions are exactly the same:

It is exactly as leaked code. Probably, you tried to rewrite it on C++ (without luck) and after it used leaked Python code as is.
Assuming you're not lying, how did you convert C++ code into Python in just 1 mins, I don't think it's that easy and fast to convert a Div2E Cpp code into Python.
Secondly, I just saw your submission history. There's no submission in Python before, you mean to say you learnt python in 1 min and then converted your C++ code into Python in just 1 min?
Shame on you. Because of people like you, our country is defamed.

The below four skipped are because I resubmitted the solution during the contest. You should be aware that it shows as a skipped answer when you resubmit a solution during the contest. In one contest, I was googling the approach/problem and found a youtube video with the solution. It was my fault that I couldn't resist myself, and I got a penalty for that thing. That's why I didn't cross-question Mike about why I am being skipped.
You have clearly copied the solution, and you are still arguing. Arguing doesn't make you innocent, so accept the penalty and stop cheating.
Also, why did you get skipped in Round 824? Why didn't you provide a reasonable explanation at that time? Copied in two recent rounds, nice :)
Knowing python doesn't means that you can code well in it. I also know Python and Java syntax but it's impossible for me to write a div2E code in just 1 mins in it. Why you didn't use python till now?
Also, why your python code matches with the leaked code for E?
my friend use my idea
You should not give your ideas to anybody during contest.
Attention!
Your solution 177164390 for the problem 1749C significantly coincides with solutions ddhere/177164390, Nico/177166427. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
I decided to use binary search and multiset for convience.
Some other similar examples I have found during the contest:
https://codeforces.net/contest/1749/submission/177154933
https://codeforces.net/contest/1749/submission/177154854
I learned the template of binary search from https://www.acwing.com/blog/content/277/.
And the same way to input and output is common.
Moreover, it comes to the part of multiset. The submissions I displayed above are also similar. The same idea brings about it.
Sorry， I don't know that I have set the public access permission of the code and used ideone.com.Also，I do not know the ideone.com.
I would like to complain about the duplication of my code.
Although my submission 178346905 is similar to xuduo131413's submission 178345980, I don't think this is evidence that I cheated.
The core idea of this question is very simple, I believe that we are not the only ones who have duplicated code, and I believe that the administrators are aware of the extremely high rate of code duplication on the easier questions. There is no suspicion of cheating.
Attention!
Your solution 178339322 for the problem 1740C significantly coincides with solutions Roundgod/178334608, LiuRunkY/178339322.
It is truly interesting that I wrote nearly the same code with someone I know. As I submitted later than Roundgod, let me explain my in-contest behavior.
The implementation comes from simple insight that we only need to separate sorted array into three continuous segments (fixing maximum or minimum one). My previous submission 178338132 did not aware that any cutting point is acceptable and got WA, then I correct this case in the next submission 178339322 (which is the judged coinciding one). My two submissions have the same structure and clear reasoning, showing that I worked out the solution independently.
It is not rating that matters (and it seems that mine is not affected?), but my honesty and discipline. I think my in-contest behavior proves my innocence.

WTF？So nowadays you need to carefully choose how you write, or maybe intentionally obfuscate some three-liner code so that it doesn't coincide with anyone else? I didn't cheat and don't want to explain any further as it seems ridiculous. I understand and respect how the rules are set to forbid cheaters, but this really seems to me like it's going to the other extreme.
MikeMirzayanov See my all four submissions for the problem until I got the correct one. sub1 sub2 sub3 sub4. See the Comment by LiuRunkY. I guess it is not hard to see this is a pure coincidence.
I performed really badly in the contest. This made me feel sad, but yet acceptable as I can owe it to my own incompetence and practice more to overcome this. Yet the accusation of cheating is totally unacceptable for me. How should I owe it for? Bad luck? Iron fist? I definitely wouldn't fall for it. Life sometimes sucks, but people's actions can help make it better.
MikeMirzayanov Please pay attention to this issue. As I worked very hard to solve the problems in contest 1747, I feel really sad about this. Here is my submission 179274012. I typed every single character by myself. I even used my own template which was not used by the other one. I submitted earlier than the other submission. Please double check. I do not know if there was a leakage or just a coincidence, as the idea behind the problem is kind of straightforward.

Sorry.
I wasn't able to look at the two submission records when the system sent me the message. Now it does seem so.
I got this message from codeforces:
This is probably due to both of us using the PyRival template and the problem being quite simple; how should i resolve this?
It's my code,and I didn't copy others codes,please revoke your penalty,thanks.It's my code!It's my code.Don't slander me.Please give me the evidence of plagiarism,else I will think you are just a joker.

we used the same logic to solve the problem , and also the style of writing the code matches but there is no way that i have cheated on this problem there are thousands of participants giving the contest so the logic and writing the code style may match, its a common sense , how can i cheat on this problem this is just a coincidence that our writing style and logic matches
I don't know them. And I code it on my own local device/sublime text. This is just a coincidence. coincidentally we are using a similar template. In this question, we have used common variables names like ans,x etc.And logic of this question was pretty obivious.Also, .similar means logic is same.
Please MikeMirzayanov look into this matter and remove my penalty.

MikeMirzayanov Sir , Please give back my ratings
.

I am new to the codeforces and I was unaware of the violation rules . I accept my mistake . This was my first time and i assured u that it won't be repeated again in future . I request you to give me one more chance and I also request you to give my ratings as I fully assured that it won't be repeated again.:(
cheating is cheating
Hello Sir!!
Hope u doing well
Just now , I have received a message from system , that my solution matches that with that of a user( i am not mentioning it ) . The problems was 1731D and we are aware that one part of the question(in which we had to find maxima for each k size square as already a renowned problem). I just added binary search to that already published solution. And as per rules, we are allowed to refer to articles published before the contest period.
It is my kind request to please accept my solutions and please revert my ratings. I know these types of blogs gets ignored but still if possible see in my case.
Below attached is the link from which I took one part of the question , I just added binary search in my solution.
Link to the article(Refer to deNsuh comment(published on June 23, 2020)
My solution — Akpr/186930449
Plag Solution number — aaditya_20/186926164

Hi MikeMirzayanov sir, I have copied a function from here during contest,also i have commented the source of that in my code link. May be its enough to show that we both have copied from same source, which is already published before contest so please look into the issue.
Thank you!
Heyy Can you Please if possible add this to the comment in the blog i have written Tagging Una_Shem and MikeMirzayanov
Hi. I don't see any evidence that the code was published before the start of the competition. Can you show it?
Yes Sir MikeMirzayanov
See the comment written by deNsuh
2nd comment from start
as can be seen i have just added binary search to the above pre published code
My solution
I hope above evidence convinces you
Do tell if any other thing is required MikeMirzayanov
Basically i found out the minimum numbers in all k*k size matrix from 1 to n (this I took from pre published code) and then checked if if any minima is greater than equal to k then that qualifies to be our answer. Then since we know that if k1 is answer then all values <= k1 will also satisfy so I used binary search
Una_Shem MikeMirzayanov
In aritcle it is seen the comment was published on 23 JUne ,2020
I also recently got a message from Codeforces team that my solution 186944749 matches with 186930712 and 186939456 . But I had used the code from the Leetcode(online site) blog which was posted two years back as given comment (link). So MikeMirzayanov Sir please check it once I had not copied any other contestant's code.
MikeMirzayanov Is there anything else i need to provide for proving that the code was published before the contest conducted .
Thks
Hey on 30th dec i gave contest but i was marked with this issue. actually i have 2 accounts testcheck and brag_sahil.. Of which testcheck is my new account as we were told to do this by my college and brag_sahil is my official CP account . i dont know why my ratings are reduced... please give my ratings back. its the me who myself wrote the two codes..please return my ratings ... my college told to submit me on testcheck too...

Hi. Please, read my answer below.
I have been informed of an alleged matching of answers in a mail received from codeforces. If possible, I would like a review of the same because the linked solutions are all different in approach and writing (they have used segment tree, stack, sparse tree, sets, whereas I have used two maps). I would really appreciate if the code is reviewed manually please since I have written the code by myself without any external help or copied code.

Yes, you are right. Your solution (and actually all except 187830914) weren't punished. It is just a side-affect I punished 187830914 in your group.
Thank you so much! Really appreciate your effort and the platform :)
It is just a side-affect
I just have one clarifying question. So their match is a star with 187830914 in center and you send mails to everyone in connected component?
I think there might be some coincidence.I have no idea about it.
Such a coincidence! 187833171 vs 187832229.
Hello, my submission 187798307 of 1779C - Least Prefix Sum was coincided with four submissions. However I never leaked my code with others and my submission was the eariest among these submissions. I checked their code and it is true that they copied my code and I tried to found out who leaked my code.
_Hridoy, a paticipator of the contest, was in the same room with me. After passing the 1779C - Least Prefix Sum, he immediately locked his problem. About half an hour later, my code was submited with a few changes by four guys.
I have contacted _Hridoy and try to find out answer. But he doesn't reply my message. So now I come here for some help.
Maybe website managers could find out whether my code was read by others during the contest.
Hi i got message from system, that i cheated in edu 141, but i dont, our codes has simillar idea but we have simillar styles and eays to realize our idea, its wrong please, correct that , MikeMirzayanov
I'm guessing you just copied it from me.
I dont even know who you are
Hello, I receive a message about my solution 187807688 for the problem 1779D significantly coincides with solutions tatyam/187759083, and others(27 people total).
I don't know them(27). First, I don't know why they are 27 people. If there is a person's solution which is similar to mine, maybe I would trust more. What's more, when I check the differences between my code and others', I find that there is many defferences. Maybe it's no exact to show my opinion. What I mean is that, my code is not similar with others' at all... Last, I come from China, they and they come from many place, there is no possibility to cheat with them。
As a student, I can't cheat with others. I hope you can help to solve it. Thank you every one very much.
Hello Everyone, This afternoon I got a message from system that my submission http://codeforces.net/contest/1775/submission/188756113 for 1775D, has been found significantly similar to http://codeforces.net/contest/1775/submission/188751623.
I don't know why I was warned because I didn't contact anyone else during the contest. I think this is just a coincidence. Judged only because the dijkstra is the same? You can find that we're from same school in profile. It's normal to have the same templete.
I hope to prove my innocence, thank you!
I changed my comment for once. Cause I thought 1775 is the newest one. Just didn't check the contest. And I can Absolute guarantee I didn't cheat in any contest.
I got a message from system that my submission http://codeforces.net/contest/1775/submission/188758072 for 1775D,has been found significantly similar to http://codeforces.net/contest/1775/submission/188748087.
I have no idea why I was warned because I didn't contact anyone else during the contest.Thus,I can't get the code by Antichain.I think it is just a coincidence. This problem is kind of native;the same idea of cource will lead to similar code.Besides,Antichain was my classmate,so out code stlye may be similar.
I hope to prove my innocence.Thank you!
Hello everyone i was warned that i copied a code https://codeforces.net/contest/1782/submission/189343513 I dont know how to take this but I DID NOT INDULGE IN ANY UNFAIR MEANS. i have solved this problem by myself and did not share this code to anyone during the contest i dont know how i can prove this but it is really heartbreaking and makes me question the amount of hardwork i am doing on cf..i have given all contests just by myself regardless of results.and have never copied anything ever..I REQUEST CODEFORCES TO PLEASE LOOK INTO THE MATTER AGAIN..please help if anyone knows more about this

I just thought about the problem for 63 min and debugged for another 17 min. I promise the code was writed by myself. Why I'm judged as a cheater?
Someone else got my code through his own means, such as viewing my code copy through the room, etc. Why did I solve it independently and the code that I submitted first was judged to be cheating and plagiarism, this is the code I solved myself, I looked at the plagiarist's code, his submission time was dozens of minutes later than me, why I was skipped, please revoke the penalty against me and return my rating score to me.

I didn't share my code with anyone, and I didn't even share my idea with anyone before contest finished. I use my local editor to write code, so my code is unlikely to leak.
This problem is simple, and the solution is short. So coincidence happened. So check this again please.
hello codeforces, today i got a mail "Attention! Your solution 190384743 for the problem 1792B significantly coincides with solutions srijitapaul1977/190384519, wintersoldier2004/190384743. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).

I wrote a very basic solution for this problem,accpected for tis problem just need to use trie,and my algorithm templates are all derived from acwing(https://www.acwing.com/blog/content/404/).I think it's a very coincidental thing.I want to get my rating.
MikeMirzayanov please check code again please!
Hi MikeMirzayanov, in the most recent div.3 problem E I got a plagiarized solution from oliverpanda_ we both used the same geeks for geeks article for problem E which is a public source that was released before the contest, this should not be a violation... Here is the link for the geeks for geeks website: https://www.geeksforgeeks.org/find-two-numbers-sum-xor/ Thanks in advance!
Why do you even use another source to solve a problem insted of doing it yourself?
I read the problem a few weeks ago and instead of rewriting it I just used the available code on gfg... Is this the correct place to post about it?
The point of this contests is to gain experience of solving problems by participating in the rounds. Also they help you to check your true level in competitive programming, and copypasting solutions ruins that opportunity for other people. So i think that any sort of rewriting problems should be banned and sincerely you got what you really deserve. I hope all people that did the same thing were banned from this div.3 Round :(

i was not aware of such things and i am doing it for more than 1 year and i didnt cheat in any of the contest and I don't know how i came into this from next time i will take care of all of this , my 3rd submission(191140593) of the round type db forces div1+div2(rated) got leaked or matched with others code but the solution was pretty easy to think and i was very obvious to come up with that approach the best i could have done is just changing my variable but that didn't work in that case what am I supposed to do ???

Hey MikeMirzayanov ! I recieved this message that my code 191949423 coincides with 191986416 solution.
This is because I used a lazy propagation source code from GeeksForGeeks (link attached) -(https://www.geeksforgeeks.org/lazy-propagation-in-segment-tree/)
Help MikeMirzayanov. Please look into this matter.
Hello!
I apparently also received this warning, in fact I also used the code from the link https://www.geeksforgeeks.org/lazy-propagation-in-segment-tree/
System Alleging me for plagiarism MikeMirzayanov
Your solution 191878626 for the problem 1791B significantly coincides with solutions Bilal04/191878626, sam1617/191903840. I firmly deny the allegation that I copied someone else's code or provided any form of assistance to other contestants during the coding contest.
In my code, I have used variables like 's' representing string, 'x' and 'y' representing x and y coordinates, and 'f' for flag which is very common, I am confident that the code I have submitted is entirely my own and that I have followed all the rules and guidelines of the contest.
This is a pure coincidence and I hope that this issue will be resolved quickly and fairly.
Hey MikeMirzayanov I got a plag message for 1786B for my solution 192337404 but other than making an array of the differences I fail to see how it is similar to 192329389,192335667,192338432. Is there any other solution for div2B because this was just a simple code I did by seeing and analysing the test cases. I have not used any online IDE , everything was coded on VSCode. I have no screen recording or anything to prove but it was a simple code with fairly common variable names. Can you please look into it
MikeMirzayanov It has been a month without update. Do you plan to address it?
Attention!
Your solution 192910652 for 1788E - Sum Over Zero significantly coincides with solution etherinmatic 192947358. ...
The problem was pretty similar to this one: 1667B - Optimal Partition (I was the setter of that) and the solution can be found here: https://codeforces.net/blog/entry/102013.
MikeMirzayanov please look into it.
Yeah, I figured that I have seen such a problem before so I copied and edited the solution given in the editorial.
I got +ve delta after so long, just to get notified that my answer seems copied :) woah! Copying, and still being pupil?
Edit: I got it, I did use a public IDE. Thankfully, good to know they just gave a warning and didn't block/banned me.
Mike Mirzayanov, I got a message that my solution of problem 1793C coincides with someone else. I just wanted to clarify that it was just a simple two pointer problem and just the same name of commonly used varibales such as prev, i, j, maxi, mini (which I use in almost every contest as u can check) is what it all had in common.
If there is any way in which a proof can be submitted then I'm ready to do that from my side but would not entertain false allegations of copying from someone that I have never heard of. The logic of the problem too was not that hard and involved just 20-25 lines of code.
I would like the codeforces team to look into the matter as I haven't cheated nor do I need to and also have had a clean history in contests.
I expect a response soon.
me too, infact i made two different submissions out of which one was partially correct. the other one with a slightly modified logic got accepted, in fact in the final submission too, I commented the previous version. But I realized later that submissions made to online IDEs remain in public domain.
I'll take a close look at it (and other similar cases) before the next round.

Sorry,but this is a misunderstanding.
We have the same idea,but unfortunately,we are regarded as plagiarism by codeforces,but our solutions are different.Can you return our Rating back?
MikeMirzayanov
Ok, Mr. Shen Yufan and Mr. Li Chenyu, can you tell me why you write almost the same code by coincidence and you are all from Shaoxing?
This is a misunderstanding. We have the same idea, but our solutions are different, and there is no plagiarism. Unfortunately, we are considered by codeforces as plagiarism.Can the official return the rating to us?
My solution for B (193840653) on the last contest coincided with another submission (193850235), however, by inspecting the codes, you can clearly see they are quite different, and besides, the solution for that problem was really simple.
MikeMirzayanov, I think the system was overzealous on the last round, Problem 1795B. The code is only 14 lines long, and besides looping and IO, the logic is about 7 lines. It's a really simple problem of checking if the value in question is a right end of a segment and the left end of a segment, and I think the system flagged a false positive. (I was using VSCode on my personal machine and all my code is on a private repo)
Msg below: ~~~~~ Attention!
Your solution 193839943 for the problem 1795B significantly coincides with solutions thahn106/193839943, iamdikshith/193899054. Such a coincidence.... ~~~~~
My rating was not reverted, but my submissions were invalidated (verdict skipped). Sorry if this is not the right place to ask, I just followed the link in the message. Is there something else I should do? Where is the right place to ask about things like this? Can I resubmit my solutions to clear them from my unsolved list?
Thanks for the great platform; hoping this will be sorted out quickly.
Not done
I mapped this question with one question on leetcode named corporate flight booking. This was just a coincidence that the code matched it might also be because of code snippets.
Dear sir, MikeMirzayanov
I recently got message from system that my solution 195163597 is same as others, several names were there. But I did not copied from anyone. You can see I was getting MLE in my initial verdict, then TLE and WA. My initial logic was making all elements 2, which I was trying for atleast 45 min. After getting so many wrong verdict I removed all my code and started again.
I removed all my template in order to not get any TLE( as earlier I have suffered TLE because of my template ), and wrote the basic logic divide by minimum every time, which unfortunately came very late. The question logic is common for everyone. It does not mean that everyone have shared the code. Please correct your plag checker.
I know it was mistake but we who do not cheat and give a lot of time we get plag, just like other cheaters hurts. Please look into this.
Please correct it and improve your plag checker system, and thanks for such great platform for CP
I was doing codeforces round 855 div3 on ideone.com due to some glitches in my computer. I was not able to use any ide and due time was already less I think someone copied my code. I was in rush and I promise that is won't be repeated ever in future.
If you want to prove how I did this question or why I did this like this or any way in which I can prove that I did this question myself only, please tell.
I assure you I can prove anything
I've passed this problem before, and I submit someone else's code just to help someone else test it
Hey I just got flagged for plagiarism for 2 problems in a contest.
1802C
My submission
Other guy's submission
1802B
My submission
Other guy's submission
We were using the same Python fastIO template by PyRival found here If you look at our submissions our logic and code is completely different and only the template is the same. Please look into this thanks. Also just for reference are we not allowed to use publicly available templates?
In the previous round, Nebius Welcome Round (Div. 1 + Div. 2), my solution about problem C was skipped. However, I didn't show my code to anyone. I think it's probably the std solution is to short. Please roll back my rk, thanks.
it was skipped because you submitted another solution later in contest, everyone's rating is rolled back right now, don't worrry
emmm, why should my first solution skipped just because my second solution, because I just copy my self?:(
No. because you submit another one, only the last one counts, all previous gets skipped, but it does not affect anything so no need to be worry
But it seems that, my rank get lower than in-competition. Because the score I got of C become lower.
Yes, that is the penalty system, since you submit another one, you get higher penalty, and +50 for resubmitting aswell
Well, I thought it would be like ICPC though, where only the first time you AC count. Thank you.
My account got flagged for plagiarism on two solutions in Round #857 which were supposedly similar to 8by8's solutions.
1802B: 196604900 (mine), 196609786 (8by8)
1802C: 196647517 (mine), 196624106 (8by8)
While all the submissions use the pyrival fastio template (which is the majority of the code), the logic used by 8by8 is very different from mine.
8by8 seems to have already gotten his rating change back after posting this comment
Haven't gotten my rating back yet.. MikeMirzayanov please look into this thanks
Hi MikeMirzayanov,
I have just received a message saying that my solution in the last Div.4 G2 coincides with someone else. The round is unrated for me why would I need to cheat or share my code? Apart from that, There was 30k people participating in the round, in addition that G2 solution with pretty much easy, so there is a high probability that solutions would coincide with each other. I have been participating in 140+ contest, so it doesn't make sense to cheat in my 141 contest and specially it was unrated. I hope you resolve the issue.
Thank you!
I use Ideone but I don't know why my solution get leaked and also I don't know him personally and that code was written by me and I not copied it from anyone.
I copied Binary Search to find square root snippet from a user of high rating before the contest .Maybe some other person also copied that snippet.
sorry but I am using idone.com for code so that the but I don't know why this happen and why my code was copied because and this was written by me and not copied from any one.
Actually I have used ideone.com in public mode and someone copied my code from the ide. But it is promise to you that I will take care for this for the next time. It is request to you to not deduct my rating as it will have a negative effect on my rating. Next time, Surely I will use offline Ide. Again Sorry for violating Codeforces Rules unintentionally.
Today, I received an e-mail fo=rom codeforces that my solution 199668766 for the problem 1808B significantly coincides with solutions anvithnov6/199668766, Ritvik_Vakayala/199679155. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked. I have written my code in CPeditor and submitted the same code during the contest.Now After a week,the constest has ended I received the above mail.Cpeditor is an offline tool and there is no chance for a unknown person to go through my code during the contest hours. So this is a coincidence.
e
I did not copied someone code or made anything public nor did I reached any publication but I got a message from codeforces that my code is very similar to someone else I don't even know but I would like to clarify that it would just be a mere coincidence nothing more than that also I looked upon the submission that it said matches mine and that code was also completely different from mine so I would like codeforces to look into it
Dear Codeforces Team,
Thank you for bringing this to my attention. I apologize for any confusion or misunderstanding regarding the similarity of my solutions to those of other participants.
I can assure you that I did not intentionally violate any rules or engage in any form of cheating. I always strive to complete the tasks assigned in Codeforces competitions with my own solutions and do not seek any unfair advantages.
I understand the importance of fair play and maintaining the integrity of the competition. I will take immediate steps to ensure that this does not happen again in the future, including being more careful about where I publish my code and double-checking to avoid any unintentional similarities with other participants' solutions. I didn't do anything wrong in the solution no 201315917 200757213 200759196 & 201551866 . please give me my rating back
Please let me know if there is any further action I should take to address this issue. I assure you of my commitment to upholding the highest standards of ethics and fair play in all my future Codeforces competitions.
Thank you for your time and attention.
Best regards,
THE_AK47

My trick is that I make my coding style very different from others in easy problems so no coincidences
Hi, I received a mail stating that my solution coincided with a few other solutions for CodeForces Round 867. "Your solution 203271332 for problem 1822C significantly coincides with solutions DottedCalculator/203259035, amaan_272/203271332, prajjwal_04/203325553, sandy3006/203328297." My solution is as follows
The other solutions are: (i)
(ii)
(iii)
Since the code is pretty small and the logic is simply returning the sum of squares of the number greater than the input element, incremented by 1, it coincides.
I want to assure that I did not share my code with any other participant nor did I copy it from any other participant.
Provided the size of the code and the logic, it just coincides. Why I used Python instead of my commonly used C++ is that Python has a dynamic data type, thus, I wouldn't get stuck in "Out of bound" errors.
I request you kindly not skip me out of the contest and reward me with the contest points as I haven't violated any rules intentionally.
User ID: amaan_272 Contest: Codeforces Round 867 (Div. 3)
my submission for the problem C 203691644 in codeforces round 863(div 2) has been flagged as a rule violation because of it's similarities to the solutions of Svizel_pritula, Aku30, ek3ru8m4 and dmenezes with ids 203696670, 203691212, 203694434 and 203695366.
I think we all used prime array to speed up the code. It constiutes so much part of our code. That's why we got so much similarity in code other than that our codes are not same. range also everyone used different. prime numbers are pretty common and should not consider in code similarity.
prime numbers we used in code is already there in internet(wikipedia).
I would like to appeal my disqualification along with the other who got flagged.
Dear MikeMirzayanov, I just got false positive anti cheat detection for the problem 1826A - Trust Nobody. But it's a mistake, could you please fix it?
Why does this thread keep coming back? Please, somebody, kill it.
I have two weeks didn't login Coderforces and I receive two messages today telling me that my solution AustinJiang/201501833 for problem 1816B significantly coincides with solutions austinboyujiang/201535380, and solution AustinJiang/201511336 for problem 1816C significantly coincides with solutions austinboyujiang/201535477.
I declare that both are my accounts because I create a new account recently for me to practice, and I didn't copy anyone's code.
Please restore my score, thanks.
The two accounts belong to me . sorry for this. Please give my rate back.
Read rules when you register to contest
I used ideone in my last contest and i got a mail that my ratings have been skipped due to 1832B coincidence and i will be penalised. I didnt know that ideone codes are public and are accessible by anyone. I always use ideone and I didn't change anything in its settings because I didn't know that I have to make my code private so I was not given the new ratings and all my labors are in vain :(
There are so many online compilers like onlinegdb, CodeChef, and even codeforces has custom invocation, still, people choose(or claim that they have used ideone after getting skipped) ideone that too in the public mode for contests.
Why do people lack common sense?
Attention! Your solution 205591920 for the problem 1832C significantly coincides with solutions ljyyyds5B/205591920, qwaszxw/205592755.
Complaint regarding the duplication of Educational Codeforces Round 148 (Rated for Div. 2): I have not violated the rules. Firstly, I don't know the other contestant. Secondly, the occasional code similarity in question C does not necessarily mean that question A and question B are necessarily similar, it is just a coincidence. Finally, I guarantee that there will be no duplication with this contestant in the end\ I request you to give back mt rates, Thanks.
Hello Codeforces, I used ideone.com as a text editor which make visible my solutions publicly. This will be my last warning I promise you. Sorry for violating codeforces rules and I respect it. Next time it will not happen.

I don't have substantial evidence, and I haven't used an online IDE or multiple accounts to participate in the competition. I haven't even heard of this person from Croatia, so it's just a coincidence. Although the logic of these two programs is almost identical because the logic of the program is simple, there are still noticeable differences in the coding style.
here are codes 205875904 205853237
I’ve shared a code with my friend before the contest. When the contest began my friend has copied it. We are the same team with the same coach so it makes sense that we have the same reference. Sorry if this is answered above but I am wondering what will happen right now as my code violated the rules. We knew the rules now and this will never happen again.
does chatGPT count as a "tools that were written and published/distributed before the start of the round."
Hi MikeMirzayanov is the plag check done for the last contest (div1 + div2), I saw some potential cheaters in that, but I donot want to ruin their public image if they are innocent, please do the plag check asap before the next contest.
Sorry, at the end of the competition, I accidentally shared my code. I didn't know that others had also submitted my code. In the future, I will pay attention to this and ensure that such things do not happen again

Today I received warning message for problem C of div 2 round 877 That I have copied or done some unethical activity in my solution but i haven't done so moreover I matched the solution of those I'd mentioned in warning with mine logic is also different but don't know why I got this warning message can anyone resolve it please
Respected sir, I received the message that my code matches with someone else. I am not aware why this happened, may be because I used different snippets first time in my last contest. You can refer to my previous solutions, I have used the same snippets! I guarantee you I am not in any kind of violation of rules. Please guide me. This must be a coincidence.
Respected sir, I received the message that my code matches with someone else. I am not aware why this happened, may be because I used different snippets first time in my last contest. You can refer to my previous solutions, I have used the same snippets! I guarantee you I am not in any kind of violation of rules. I have checked the solutions with whome the solution matched, someone has used memset, I have used vectors, they are not same, you can check. Please sir guide me. This must be a coincidence.
Just stop using leaked solutions. I have no doubt that the solutions to problems C and D weren't written by you.
Sir, I have not even attempted Problem D. I am not using any kind of leaked solution. I am totally against it. This activities ruin the true hardwork. Please sir check
Hey! I received a mail from cf mentioning that my solution (208777876) for problem 1840E, coincided with dhiru_16/208810017.
Though the code and logic look similar, I want to clarify that I didn't share my solution. Also, one can see that from the beginning the other person is trying to do the question with a slightly different logic than mine. See his first solution, he was storing only the unequal indices and then calculating the answer while my logic was to use both equal and unequal indices to bloat out every possible corner case. After this, the other user also used both equal and unequal indices but this time he was freeing the blocked indices only at the time of answer printing, which was wrong, he has to do that at every step, and later he corrected that too. So, I don't think that the other guy has cheated with my solution, if he has to cheat then, he might have submitted the same code logic at the very first. It's really a coincidence that our code and logic match.
Also, I never cheated on anyone in the past, this is just a coincidence. Please do the needful!.
Thank you
This is the second time you've been caught doing this. The codes are not just similar, they are the same. Also, you are from the same location. Given all this, I refuse to believe in such an incredible coincidence.

The solutions do match, but it is possible to come with the same logic. And the code being trivial matched with couple of people. Also I don't know other users and even the locations are different.
Today I received warning message for problem C of div 2 round 877 That I have copied or done some unethical activity in my solution but i haven't done so moreover I matched the solution of those who were mentioned in the warning, logic seems to be identical but not the code. It was more of a constructive or just pattern finding problem so there are very high chances that someone gets same logic or identical. I have been doing codeforces from last 3-4 years. But had never done such practice intentionally, i believe u understands the hard work and dedication it takes to being consistently participate in contests, so i would never think of doing such activity. I just wants to say i haven't done any unethical way, it will be really great if u could rejudge this. Also i don't know any of the user mentioned in the list, even they are not in my friend list and you can also their and mine location.
my solution 208345874 for the problem 1839C not at all coincide this was my own solution i used comp function which isn't used in any of the solution provided by you.This isn't fair this was a straight forward logic and could be used by anyone.Please don't skip my contest this demotivates me very much.Should i stop giving contest on your website.This is second time in a row i am being plagged in such an straight forward question who's logic can be matched with anyone.Please don't do it give my rank to me again.I am not at all cheater. Thanks regards
Your solution 208485296 for the problem 1838B significantly coincides with solutions Nitesh_Jangid_/208505350. Please Mike, guide me how these are same. We both have used different data structures. Our technique is not similar, our runtime, memory storage is not same. I don't know this guy! I have written this code in my VSCode. please help me__
Both of them were my accounts, that's why there were same codes. Is that a crime to submit from two own accounts? Didn't know that sorry. Won't make the mistake again :"")
Hi MikeMirzayanov,
I just received a message that my code is identical to someone else's code. I want to say it's just a coincidence. I independently programmed in the competition. Perhaps because many people have similar ideas and written similar code. I hope the punishment can be revoked, thank you!

II have solved the code without any external assistance and with my own logic, That question was a constructive algorithm problem and that type of problem can be solved with only unique constructive ideas which can be same for various people I have seen the solution of other users, there are some coincidences like the ways they have printed the result but all the other parts are different.I have implemented the code on my own. I am a continuous user of this platform and solving problem on the platform for a very long time. I hadn't cheated. I request you please resolve this matter.
.
MikeMirzayanov Please look into The Matter Sir
I think I have used ideone in public mode by mistake and I was absolutely unaware that someone can see my solution there because of which my solution has been copied by somebody/ or it can be an absolute coincidence! Sorry for this but I will take care of it from next time while using ideone. Please have a look into this . MikeMirzayanov System. Question C of the recent educational round 150 div2 round caused this issue :( . Please revert back my ratings. 209462050 for the question .Please revert back my ratings
hey MikeMirzayanov please go through your messages i have texted u regarding an issue in system testing
I have rather referenced my reasons in a message to you regarding it
Hello,
I received an email that my solution for Problem A on the past edu round 150 was similar to another user. Namely, https://codeforces.net/contest/1841/submission/209416596 and https://codeforces.net/contest/1841/submission/209391885
I believe this to be purely coincidental as the solution is a very straightforward, single line if statement.I also used my own personal IDE and did not share my code with anyone else. Is there anything I can do to get this cleared up?
Thank you
I have used ideone compiler, and my logic was ll n,k,g; cin>>n>>k>>g; ll ans=(n-1)*(((g+1)/2)-1); ll x=k*g-ans; if(x<=0){ cout<<min(k*g,ans)<<endl; continue; } x%=g; if(x<((g+1)/2)){ ans+=x; } else{ ans-=(g-x); } cout<<max(min(k*g,ans),0LL)<<endl;
which I have just written in a single line . I think somebody has codpied my code. Hence, I request you consider it.
I have given all the contests on ideone.com compiler and I didn't knew about public and private mode. I usually write my code in compiler and when all test cases are run successfully i copy it into codeforces ide and submit it straightaway. please don't affect my ratings for the contest CodeForces round 880 div 2 because of my submission no. 210138558. this might have been done without my knowledge and I will take care of this from now on.
I had no idea that using ideone would lead to someone copying my code. I was having issues with my compiler and so I used online compiler please don't take any strict action
Hello MikeMirzayanov, I have received a talk from System that my solution 210135163 for 1836B coincides with several others. In the solution, I made a formula to solve the question. If any other random person were to make a formula for the same question, he would also get the same thing. I didn't cheat or ask for help for this. I don't think formula based approaches should be plagiarized as several people can easily get the same formula. Also to verify that I do actually have the skills to solve it, I also solved the C question (Div. 2) in the same contest.
I request you to please look into the matter.
i have not copied any question and you still have deduct my rating -118 is this a joke to you guys ?? i am trying to increase my rating and you guys dont even hesitate to put penalty on questions.. i am tried of this how can know if some have similar answer.. i just have find ans i code it i dont use templates this is wrong with you guys ?? you are there to judge template ??
i don't know why you have skipped this question but i want my rating back if it is just bcz.. i dont use templates
I don't get why do you guys have so many collisions, I never had any collision issues, even with problems with very similarly written answers. Maybe change the way you write code a bit, different variable names, macros etc? Also, a piece of advice for you. You are newbie right now, the time when you should worry about losing rating hasn't come yet. Focus more on problem solving and improving your skills than contests
I wrote my code in ideone compiler and it would have been on public mode ,so someone or maybe my friends would have copied it or either submitted my code with some slight variations.I don't know why I am accused of it.Kindly revert my rating for CodeTon Round 5(Div 1+ Div 2).The assure you the mistake would never be repeated again and from now onwards I will use my personal ide or vs code for the same . Thanks!!
If there are two ppl with the same code, only the man with last submission be skippped. Dont cheat.
Dear Codeforces,
I am writing to address an urgent matter regarding my recent participation in Contest 1847. I would like to provide additional information and clarify my position in order to demonstrate that I did not engage in any form of cheating during the contest.
In particular, I want to focus on Problem B of the contest. Upon thorough analysis and self-reflection, I believe there may have been a misunderstanding or misinterpretation of my code or the approach I used to solve the problem. My intent was solely to solve the problem within the given constraints using my own skills and knowledge.
To ensure transparency and fairness, I am willing to provide any additional information or evidence that can help clarify my situation. I understand the seriousness of cheating allegations and the impact they can have on the integrity of the competition and the Codeforces community as a whole. Therefore, I am fully committed to cooperating with the investigation process and providing any necessary explanations or code walkthroughs that may be required.
I value the Codeforces platform and the opportunities it provides to developers and programming enthusiasts worldwide. It is disheartening to be accused of cheating, as it goes against my principles and the spirit of healthy competition that Codeforces fosters. I have always strived to abide by the rules and respect the code of conduct in every contest I participate in.
I kindly request the Codeforces Support Team to review my code submission, contest activity, and any relevant logs or records to thoroughly investigate this matter. I believe that a comprehensive analysis will clearly demonstrate my adherence to the contest rules and validate my commitment to fair play.
I would appreciate any updates or guidance on the investigation process, as well as the estimated timeline for reaching a resolution. Please understand that it is crucial for me to address this issue promptly, as it has the potential to negatively impact my reputation and future participation in Codeforces contests.
Thank you for your attention and consideration. I look forward to a fair and unbiased assessment of my participation in Contest 1847 Problem B. If there is any further information or clarification needed from my end, please do not hesitate to reach out to me. I can explain each line of my code, if you need. I didn't use ideone.com, but I think it's because it's not the complicated problem and most of the people use almost the same logic.
Sincerely, Fayzullo Fayzullo7_PM
It is not first time: you have recently been caught cheating. This time, the code is literally the same as the leaked code. I see no reason to roll back the punishment.
I have received a email stating my code was similar to others but it is my own code .please guide me on how I can prove that the code is mine.
I got two emails today about code duplication flagged in my solutions on the recent combined round 884. I looked into it and the issue is just that we both used the same long template file, which has been available on GitHub for over a year and also has been posted in a Codeforces blog. Actually it's not exactly the same version of the template: it seems the other person mathdude42 pulled some earlier commit and also made a few minor edits of their own. Anyway, our actual solution logic (in
solve()near the bottom) is really quite different for both problems, but I do see how we got flagged since the solution logic for these problems is very short compared to the long template.Here are links to back up the explanation above:
I'm basically assuming this is a normal misunderstanding and the plagiarism flag + skipped verdicts will be fixed once a human is able to look at the links above. Please let me know if there's anything else I should do to help this case get resolved. Also, are there any steps you'd recommend to prevent this from happening again next time there's some problem with very short/simple implementation?

Same happened with me.
Your solution 213350163 for the problem 1844D significantly coincides with solutions SamarthS/213350163, akshitnandan/213378000. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked. My submission: 213350163 His/Her submission: 213378000
Please note that the question has two approaches (that I know of): 1) Mentioned in the tutorial about finding the MEX of the divisors 2) The one I used: storing the possible characters for each position and assigning the minimum of them
In my approach, please note that the required code is very small given the logic. Given this fact, it is very likely the order of operations done is similar by people using this logic but please note that the other person's code has totally different variable names and writing style.
I completed my code way before the other person and moreover I do not even know that guy. I do not have any motivation to share my code with a person whom I even don't know. I have not shared and will not share my code with anybody during contests.
Also note, that I did not use any online compiler. I wrote my code by myself on my own in my vscode and used the compiler downloaded by me.
MikeMirzayanov please take a look at this and do the needful.

Today I got this message, but I solved this problem completely on my own on my vscode.If you will observer the approach I used and the other person with whom my soln has collided is same. And in that approach the code bound to be like this You will make one table for storing which characters can't be used with the respective cell and then use for loop to reach the correct char to be used .... Anyone would implement this logic in the similar fashion.
And you can see that coding styles both the solution is completely different.
So, I request MikeMirzayanov to please take a look into this.
Your solution 213354195 for the problem 1844C significantly coincides with solutions eagerbeagle/213354195, rahul4005/213361055. Such a coincidence is a clear rules violation.

I would like to make it clear that this is because both the user have the same template(code snippet) used. the logic can be different, for the proof I used the template from this submission -https://codeforces.net/contest/1775/submission/188690000 which is dated quite before the actual contest date. I would request you to please check on this as the main solution is different for both the users and the possible reason for the plagiarism is the use of same code snippet. And as far as problem A is considered, the solution was just printing the sum of a,b so it can be same coincidently. I will make sure I dont use the same snippet again if that too violates the rule. I request you to please check this and also please dont let this affect our ratings.

I received the message of significant collision of submission with others today for 1843D of Codeforces Round 881(Div 3). The contest was so easy that there is high chances of collision of answers. The problem was very easy and standard . the solution had a simple use of DFS which is a standard algorithm. I had format of standard answer with me for my practice and I used that. I request you to kindly remove the copying allegation.Please I will be more cautious in the future ,i have not cheat it please.Please give me back my rating, as it holds great value for me. Thank you.
Please consider it for last time,i will take care from last time and i will not publish the code in ideone.com,please give me my rating back @**MikeMirzayanov's**

hxsjhxsj is another account of hxsj and belongs to the same person. I solved the problem entirely by myself.

After final System testing of some of the previous rounds to remove cheaters, my ratings are not visible. I have not cheated in any of the rounds as can be seen in my submissions. I am new to codeforces. Kindly help me to get me my ratings back. Whom should I contact & how to get my ratings back?
I have become unrated even though I have not cheated. Also, I have not received any message regarding plagiarism in any of the rounds in which I have participated previously. It has been more than 24 hours like this now(becoming unrated for no reason). I thought it would rectify itself but ratings of other people are visible & not mine. Kindlly help @Mike Mirzayanov.
The rating rollback applies to everyone, and it can last for some time. It doesn't necessarily mean that you cheated. If you didn't receive any plagiarism message from the system, simply wait and you'll eventually have your rating back.
Dear Codeforces Team, I wanted to bring to your attention that I recently received a plagiarism notice for problem D of my last contest. However, I want to emphasize that I did not cheat or intentionally copy any code. The similarities in my solution to others might be attributed to the utilization of common logical reasoning and problem-solving approaches. I kindly request you to reevaluate my submission, taking into consideration the possibility that my solution was derived independently. Upholding integrity and fairness is of utmost importance to me, and I have always strived to maintain these principles while participating on the platform.I greatly appreciate the efforts made by the Codeforces team to ensure a plagiarism-free environment. I sincerely believe that the resemblances in code were coincidental rather than a result of deliberate plagiarism.
I have did it on public ideone. Com so some one have copied my code you can see my code during my first attempt I have got error and wrong answer after that I have corrected my code with this you can truly know that I have did the code own with out extracting from other websites. I request the system to check it again and remove my plagarism
read the rules!
I don't know how my solution match with other solutions . From the next time onwards I will be more conscious of these things and will not repeat again please revert my rating
You have 4 skipped contests in row. Cheater
You can just see my no.of attempts also I have tried and solve it
Hope you will be banned soon.
You guys are cancer for codeforces.
.
Ah this has became a common excuse for cheaters...they used to cheat and always give this cheap excuse...I have used ideone.. Oh comeon bro...who the hell use ideone nowadays...bahana bhi aisa banao ki pkde na jao
It will ve better for you to practice 800 rated problems now...rather than copying from somewhere during the contests
Good luck !

MikeMirzayanov
@MikeMirzayanov I have been plagarised for : Your solution 215615024 for the problem 1851E significantly coincides with solutions But the code I wrote is different from them, In my code you can clearly see that i have used DFS in graph that is the standard method to solve graph problems. I can explain My process in detail
There is a problem F with a more difficult thinking but simpler code that shows that I have the same code as others, and I think this problem is thinking about the rationality of the ordering rather than the code, so I don't think it is reasonable to say that I copied others
In 1849D.I just use the greedy and enumerating the prefixes and I've done it all by myself. It may the same idea with others but I don't think it is reasonable to say that I copied others.Please give my rating back,thanks
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back
Codeforces Round 892 (Div. 2) in this round i copied 'A' ，'B','C','D' questions all by myself . And I didn't mean to leak my code . And I sumbited them eariler!
I am writing to address a concern regarding my submission with Round 892(div2) . I have noticed that there are similarities between my solution and that of another user, but I would like to clarify that I have not engaged in any form of cheating or plagiarism.
While I understand that the logic in my solution might coincide with someone else's, I can assure you that my approach and implementation are entirely original. It is not uncommon for multiple participants to arrive at similar solutions, especially for well-defined problems that may have limited viable approaches.
To further support my claim, I would be more than willing to provide a detailed explanation of my thought process, the steps involved in my solution, and any relevant code snippets that may help demonstrate the uniqueness of my approach. please give me my rating.
I received a notification that my submission 218921356 coincides with other submission 218930647 yesterday. This is the second time I have received such a warning. The first time happened two months ago. My submission 211480048 vs other submission 211495795.
I have never used any online IDE or commonly published source for competition purposes. I believe this is merely a coincidence, as the solution to these problems is fairly straightforward. It is great to have a system check as it can prevent cheating. However, in the meantime, please deal with these false positives properly. To be honest, I am not too concerned about my rating, but I would like to appeal against this conviction. I am innocent, and it is unfair to me.

Hey Codeforces Team, I got a message from codeforces that My solution 219297072 for problem 1860C Matches with many others. As I have checked it was just the same logic all have done for this since the PBDS wasn't working in the editor I used an online one and just changed the PBDS order of key to the distance function in a set by using chat GPt I really didn't realise that same will be done by others I literally regret that I won't be using ever. I don't know how it got coincidently the same but you can check it's the same logic all applied even with the users who used PBDS that just wrote the order_of_key function Still I am sorry that I converted and pasted, There is nothing about the cheating thing I don't know seriously the logic was quite clear I guess and all of them done same nothing far to do. I request you please Remove the skipped part It was just my mistake won't be using online compilers and GPT for the purpose Please consider the request Mike. Please consider the request.
Ok
Attention!
Your solution 221115308 for the problem 1863C significantly coincides with solutions Schi2oid/221115308, LBRhhhh/221122939. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

I received this surprising message today. I don't know who is LBRhhhh, and I didn't use any online IDE. In fact, this is a quite easy problem as C for Div.2, you just need to notice that it will become a loop $$$\bmod n+1$$$. I'm sure there's no chance LBRhhhh can get my code, unless there is a system vulnerability.
I was completely unaware of these circumstances, I wholeheartedly commit to exercising greater caution in the future and abstaining from the use of online compilers. I assure that its just a coincidence. I saw all the codes my code is obligated with and observed that each and every line in their code matches with each other but its not same for my submission. I kindly request that you consider rolling back my contest submissions for Division 3, Contest 895. Your understanding and support in this matter would be greatly appreciated. MikeMirzayanov
Hello Codeforces,
I would like to address the plagiarism message sent to me today by codeforces regarding my submission 222748434. I think the matching of my code with ArshAgl is coincidence as the logic of the problem was simple but I looked for submissions of others but they are similar to mine and the idea is definitely similar. The problem was very similar to 2d prefix sum and set templates. I used a same template which has been taught in a coding camp to me. Please look into this issue as soon as possible and revert back the rating changes and the solutions that are skipped. The coding camp had a similar style of writing which makes the codes same. Once again I apologize from my side.
Thank You.
Hello, Codeforces team. I just received a surprising message.
Attention! Your solution 222744018 for the problem 1869B significantly coincides with solutions xuancx/222736824, wuyoudexian/222744018. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

In case of repeated violations, your account may be blocked.
My submission for problem 1859B - Olya and Game with Arrays has been flagged for plagiarism. However, this is absolutely impossible as I independently wrote my code, and I did not use any online IDE. The similarity between my code and xuancx's code is purely coincidental. Moreover, 1859B is not a challenging problem for me, and I had no reason to plagiarize.
I don't know why I wrote the code locally myself. There is no outside transmission that would happen. I wrote my own code. Also, I don't know anyone whose code overlaps with mine. I don't know why this is happening. I don't know them at all
Issue: Your solution 224345258 for the problem 1873C - Target Practice significantly coincides with solutions rakshit.agrawal26/224345258, Mahadev5092/224425220. For example, do not use ideone.com with the default settings (public access to your code).
This is first time that I have received above mail and I was dumbfounded after receiving it because I was solving for Codeforces Round 898 (Div. 4) honestly and as fast as I could given the time constraint. I have provided evidences below that might have led to the current situation.
Evidences to above coincidence:
1. Common problem and very specific problem: The 1873C - Target Practice is a very common problem and the given target size is also fixed i.e., 10, which makes the problem more specific and thus, the first approach that comes to mind is very obvious which is using if..else statements as the cases are very limited. This approach is less tedious compared to the solution provided in editorial. Thus, it is likely that solutions match.
2. My submissions: Considering the[contest:898] was a Div.4 contest, my aim was to solve all the problems in this contest, so instead of above problem my concern were 1873G - ABBC or BACB & 1873H - Mad City. So, it is completely out of scope to waste time in sharing or finding solution of above problem during the ongoing contest. Kindly find my submissions and note their time stamps: 224316778, 224332264, 224345258, 224353014, 224420940, 224435856, 224504642.
Kindly look at the submission of 1873C - Target Practice : 224345258 and the time of submission.
Others:
Kindly look into above matter. Thankyou. MikeMirzayanov
I received this "Your solution 225150510 for the problem 1882C significantly coincides with...". I would like to make it clear that I was using Ideone. However, I didn't realize it was in the public access mode(I regularly use sublime text on my local PC). This is a carelessness from my side, but I did not cheat, so I would request that my solutions not be skipped. Thank you.
Hey team, I would like to address the notification I received, which pointed out similarities between my solution 225150510 for problem 1882C and another source. It's important to note that I was using Ideone, unaware of its public access mode, as I typically work with Sublime Text on my local PC. This was an inadvertent oversight on my part, and I want to stress that there was no deliberate misconduct. Consequently, I kindly request that my submissions not be excluded. Your understanding in this matter is greatly appreciated.
I didn't copied from anyone it is just a coincidence because i have used the ideone compiler to write the code. I don't know may be someone copied my code.
It is still your fault for making your code public, since it was stated that code sharing is also considered cheating. Ideone public source code is a well-known issue so cheaters usually check most recently created ones during a round to copy.
Be careful next time and set ideone to private.
Attention!
Your solution 227923422 for the problem 1881D significantly coincides with solutions jiangbx/227915979, OolongTea/227923422. Such a coincidence is a clear rules violation.
Firstly, I am very sorry for violating the rules, and this is my first time being warned. Actually, both of these accounts are mine, and I was not clear when participating in the competition that I couldn't submit my code to both accounts. I know it's difficult for me to prove that both of these accounts are mine. Please don't erase my score and acount, I'm sincerely apologize here again. I can guarantee here that in the future, I will pay attention to all the rules of the competition and use only one account to participate in competitions.
I am sorry that I submitted the same code on the evaluator, but the account with the same code as mine is a new account I opened. Before receiving this warning, I thought it was legal to do so. Now that I know it, it is illegal to do so. I wrote both of these codes myself, and as can be seen from the user's name, one account is WWWJL and the other account is WWWWWJL.
My solution 230570181 for the problem 1891B code unfortunately coincided with some other people. That was just a coincidence.
230560706 I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody. I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. Now onwards going to use sublime!
I don't know why I have got this message that my code coincides with other solution my solution is utkarsh_raj_13/231786180 and it says it coincide with this Soham2312/231787190 solution I have used map in my code and it is completely different. only the code has same template. I don't have shared my code neither I have copied it from other
In Codeforces Round 908 (Div. 2), my solution 231778921 for the problem 1894C accidentally coincides with other solution. I highly think this was just by coincidence and usage of ideone.com which I didn't know that it was a violation to use in Default settings. I request not to deduct my rating. It was my idea alone. I am very sorry for violating rules and this is my first time getting warned. I hope this violation is Rechecked and my rating doesnt go down. I will make sure to abide by rules and have no repeat of this. Thank you
Today, I got a system mail that I've cheated. But, I have not cheated. What I did was, I submitted same code from my two accounts. Moreover, I have done the same in the later 2 contests as well. I didn't know that I can only compete from one account at a time.
the same i copy my cood in two accounts
I am really sorry I don't know about contest instructions, so please can you recover my account please and I dont repeat that[user:mohamedblack667]
my handle wanted to recover is mohamedblack667
In the solution 231787842 for the problem 1894B, a message is there regarding solution coincides. I really don't know how it coincides. I haven't share my code file to anyone/anywhere.
It's my humble request please give my ratings back. If there is something I can do for this. Please guide me for future avoidance of this type problem.
Sorry some copied my code I published my code on ideonone.com I request you to remove my copyright.

i am sorry that i used my second codeforce id for the submision ,, i m not going give any excuse ,,, i thought this would be some sort of hack ,, which i found was completely wrong ,, i am once again very sorry about this ,,please accept my sorry sir MIKE sir, ; i have seen this email just a hour before and had done same mistake on the yesterday contest,, plzzz sir accept my sorry... and i am also apolozing to all coders community..this was my last time.
I received the following message "Attention!
Your solution to problem 1899C 233161472 with solution ......"
I apologize that this happened. This question has an almost identical question in my school's oj. I submitted it directly using a previous code snippet which is being made publicly accessible. I will not continue to submit using publicly available code snippets after this.
Sorry but it was a coincidence ..!! I will secure my code from next contest please don't decrease my rating.!
i got warning for cheating but i use online compiler and someone cheat my code from there
i got message regarding cheating but i just use some online compiler to write my code.

I dont know the person and didnt published my code any where it was a straight forward solution using map and may be many user have same solution I havent copied the solution or published it will be great if codeforces look in the matter and recheck the evaluation
same happen with me for 1899B, IT WAS STRAIGHT FORWARD QUESTION
I USE THIS ONLINE https://onecompiler.com/ ALONG WITH IDEONE COMPILER SOMEONE COPY MY CODE
Hi, I came across a message regarding plagiarism for my solution (233132820) and this was the first time I received such message when I was using ideone.com for quite some time. I had no idea about the public access of codes. I'm now well aware of not using such public accessed compilers and would use private compilers. Sorry for this, I hope my ratings doesn't get affected, I will take care of this with utmost importance for future contests.
Usually I put my solution on personal GitHub repository to account for the questions I've solved in contests. I will take care of the same and post them after some significant days from the contest.
If anyone knows, should I raise this query of unintentional coincidence through some email for support, kindly do let me know. It would help me to explain the above and save my ratings.
Thanks much!
I also did it using an online compiler. Pls return back my ratings
Why r u asking to return the rating? Ur rating is stll intact and shows positive delta
Oh yea sorry..Just noticed,
I was matched up with OmarAli.22 in a university competition. We were on the same team and I found his source code interesting and therefore, I copied it and started using the tools it had for problem solving. The source code is public and it has been used by him for months. I'm new to codeforces and problem solving. You can noticeably see in our submissions that only the source code is identical. The real logic and solution is totally different. I will make sure to change up the source code in all of my upcoming submissions so this doesn't happen again. A 40 days old submission by OmarAli.22 that shows the public source code: https://codeforces.net/contest/4/submission/233070727
These are the two submissions that were suspected: https://codeforces.net/contest/1899/submission/233191836 https://codeforces.net/contest/1899/submission/233192741
You can definitely see that the solution is totally different.

I received this mail from codeforces saying my solution 233179993 for 1899D coincides with the solution 233146009 submitted by satyapc1509. It's just a coincidence that our codes are similar. From the problem statement we both reached the same conclusion, and used map in our implementation.
Hey Mike(MikeMirzayanov) ,
I am sorry for telling you this but I cheated during the contest Codeforces Round 906 (Div. 2) problem A from one of my friend (Rahulpra) and he and I got this plagiarism notification. I wrote and copied his code from behind him and parallelly typed , when he was testing for other cases I submitted that code and that code got accepted. Due to the fact that I also use his coding headers and the fact that I cheated ( that I should not have ) he got plagiarism. I am again sorry but please do not blame him for plagiarism I am wholly responsible for that. You can ban me if you want but do not punish innocent.
Thank you
Attention Please!
I got a message from system that my submission https://codeforces.net/contest/1896/submission/234294300 during the CodeTON Round 7(Div. 1 + Div. 2, Rated, Prizes!), has been found significantly similar to https://codeforces.net/contest/1896/submission/234280820 . It’s unfortunate coincident. I don’t copy from other. This code that I submitted during contest it is totally made by me. In this contest I solved three problems and now all problems are skipped. May be rating will be discarded.
Note: This incident happened also occurred before ten month ago. But that time I didn’t care about this although I didn’t copy.

MikeMirzayanov Sir Murad134 its my 1st id and DrMurad is my 2nd id.This is my two codeforce id. I am giving a contest with my 2nd ID when my exam is running or I have work. But 25 dates (November) after solving A and submitted in my 2nd ID Then submitted this in my 1st ID (this is my mistake). Then I am not want to decrease my rating so I submitted B and C in my 1st id. I am sorry for my mistake. I have never had a skip or such an unpleasant incident before. I am new to Codeforce so I do not know all the rules in Codeforce. Please don't block my 2 ids.I will not make such a mistake in the future.
Prove : See i have given same profile picture and name in both my ids and alrady given 18 contests in Id number 1 (The_IntentorBoy).
I used idone a couple a times ,I don't know about the default settings !
Can I reflect the error of code review here? In Codeforces Round 909 (Div.3), I received an email after the game stating that my code for Problem B was identical to the code submitted by user Don_Quxote, but in fact my code template had not been reviewed for six months (and I had not embedded any external code in the solve B code). After reviewing the code, I compared skipped's code and found that the two had almost no correlation. For question B, I used the violent traversal method to pass C, D and E first after TLE, and then returned to question B, using factor reduction of traversal range to optimize and pass. And another user's code, I actually can't follow very well. Look at both codes, and you'll see what I mean when I say there's no correlation.
I am writing in response to the notice I received regarding the similarity between my solution (233437799) for problem 1898B and other solutions.
Upon reviewing the situation, I realized that my solution bore striking resemblance to the ones referenced. I want to clarify that the algorithm used was discovered by me as a solution for a previous online assessment on a different platform.
During that earlier contest, I encountered a problem akin to 1898B and found a solution which I documented for future reference. Unfortunately, I inadvertently utilized this documented solution when I faced a similar problem in your recent contest. And I think this may have led to the observed similarity between my submission and the others mentioned, since otherwise I haven't shared the solution with others during the contest.
I deeply regret any confusion or concern this may have caused and want to reassure you that my actions were not intended to violate the rules or compromise the integrity of the competition. I understand and respect the importance of fair play in such contests. I am fully committed to upholding the integrity of the contest and assure you that I will be more vigilant in ensuring compliance with the competition's regulations in the future.
Dear Codeforces Team,
I am writing to address the message I received concerning an alleged rules violation in the recent contest. My solution ID is 234058040 for the problem 1901A.
Firstly, I want to assert unequivocally that I have neither copied someone else's code nor shared my code with others. I understand the importance of academic honesty, particularly in competitive programming, and I have always adhered to these principles.
Regarding the similarity of my solution with those of users yufan666/234077867, I believe this is a mere coincidence caused by the nature of the problem itself. Given that the problem 1901A was relatively straightforward, it is highly plausible that multiple participants devised similar solutions independently. This is especially true in competitive programming, where certain efficient and well-known approaches are commonly used by many programmers.
Furthermore, the similarity in code structure could be attributed to a common coding style prevalent among programmers, which does not necessarily indicate any form of misconduct. Such styles often involve standard implementation techniques that are widely taught and shared within the programming community.
I respect the rules and integrity of Codeforces and understand the need to investigate potential violations. However, in this case, I firmly believe that the similarities are coincidental and not a result of any wrongdoing on my part.
I am willing to provide any further information required for your investigation. I respectfully request the restoration of my submission record and rating, which have been impacted by this misunderstanding. I value my participation and history on Codeforces and hope to maintain my record based on my actual performance and adherence to competition rules.
Thank you for your attention to this matter.
similar thing happened with me bro, without any mistake my solutions are skipped for no reason, what can I do if my solution is similar to somebody by coincidence.
I think we can add some useful code at the beginning of our solutions. I don't know exactly
what useful code, are you talking about macros and templates ?
Isteak_Desh9121 is my other account.So I submitted same code in both accounts. In 233107824, 233112944,234058661, 234096994 solution . I am really sorry for my actions. When I saw the first message I wan not aware about the rulse and i was busy and forget to write the comment . but somehow i submitted the same code in both of my account and i'm really very sorry of this. Next time I will be careful about this . so please accept my code this time and I will try my best to avoid this type of mistakes in next time.
it's my another account
Isteak_Desh9121 and mind9121 both are my account.So I submitted same code in both accounts. In my 234087074, 234058424,and also some other solution . I am really sorry for my actions. When I saw the first message I wan not aware about the rulse and i was busy and forget to write the comment . but somehow i submitted the same code in both of my account and i'm really very sorry of this. Next time I will be careful about this . so please accept my code this time and I will try my best to avoid this type of mistakes in next time.
I have got a message stating that my submission vaibhaviiitb/234085486 collided with akmmbh/234084119 it was a complete coincidence. I didn't share it anywhere also I don't have any idea who this person is coding flow of mine and that person's were a bit similar but that doesn't mean that I or him has copied how can you expect codes not to collide if it's just 3-4 lines of length can someone please help regarding this. I didn't share the code anywhere also I don't know who is that person the templates are completely different the only thing similar was the writing of logic in the for loop.
Sir my cf account was logined in my friend's laptop so there way cheating happened. I know this is my responsibility and I should be accountable but I was unware of it. Same thing happened today. It will never happen in future and I am really sorry for my mistake.It took lot of efforts to reach my current rating ..
just wanted to clear the air about the recent contest. I didn't cheat, but here's the deal: I worked on the contest using a shared school computer. turns out that one of my pairs had access to my code because I left it in a file on the device unintentionally. I understand the importance of fair play, and I'm just hoping you can take another look at my case. it would mean a lot if my ratings could be reconsidered. thank you for your understanding.
i think simple naming is problem not copy
my code is completely original no copy . i do not know how it is matching with some one
Both NYR_30 & Vithesh_2215 we're my accounts only
I used function from somewhere on the net for binary search ona vector of pair which i thought is legal.Maybe that would have caused a coincidence of matching solution.I will try not copying any functions from third party platforms from next contest onwards.Please give my ratings back.
Before submitting, I ran my code on ideone, probably someone copied my code and I was not aware about that, but I will take care and turn of the public mode from next time.
I don't know why this is happening with me and it happens me more than two time, I got a message from codeforces system that you solution for the x problem is coincides with solutions no xxxxxxxxxx . Can anybody please suggest me that how can I overcome with this problem.
I'm sorry about this one. I have used ideone for a few days this month and in this month I did not perform any contest too. But as I wasn't aware about this, I used ideone when my last contest was going on and I got this warning today. But I can make sure that from the next contest I will be careful. pls, don't give any penalties or blockage. Thanks a lot.

I have been participating in contests and solving problems since a long time, and this is the first time I receive such a message.

I hope you take what I said into consideration. Thank you!
Hey @MikeMirzayanov I received a message saying that my code pragati_iitk/235939000 for problem 1907B in the contest Codeforces Round 913 (Div. 3) significantly coincides with the code dhruvg190305/235941052. I am really sorry if such a coincidence has occurred. My solution is entirely my own. I am truly unaware of how it happened. It might be due to the use of online compliers. I understand the importance of maintaining the integrity of Codeforces contests and ensuring fair competition. Kindly do not impose any penalities and please do not block my account. Moving forward I will be more vigilant. I appreciate your understanding. Yours truly https://codeforces.net/profile/MikeMirzayanov
About 35 minutes ago I received a message saying that my code matches significantly with a contestant. It might be a coincidence because I wrote that code by myself. I have no idea how such a coincidence has occurred. It is possible that the code was leaked because I was using an online compiler. I am really sorry and sincerely apologize for any carelessness on my part. Please do not impose any penalties or block my account (it was written in the mail that it is possible that my account is blocked). I will be more careful from next time and won't use compilers online. It is first time anything like this has happened probably because of my lack of awareness.
I'm really sorry about my incident in the previous contest(div3 round 913).In the contest I used my friend's pc..when I submited the code I found that it was his new id.Not mine..I didn’t notice that before..I was in a hurry as the contest time is running out..that's why I just logged into my account and submit the same code(problem A) again.I didn’t know about these rules.. Sorry for my mistake.I promise, I dont make this kind of mistake again..Please dont block my account.
Hey, I was using online compiler and didn't know that my code can be viewed by others. So sorry for this mistake. I will take care of it from the next time. As this was my first mistake I hope you will understand it and will not penalise me. I will make sure no such incident happen in future. Thanking You
hello, I've completed all the three of problem of Codeforces Round 913(Div. 3) by myself . I don't know how my solution the_dead_person/235900269 of problem 1907B significantly coincides with chayon017/235937991. I don't recall any leakage of my code . I store most of my code in private. Currently my solutions are showing skipped in the contest . I will be more care with my codes. Thanks for the message. (in the message it asked me to post comment is it the place?)
Hey i'm writing about the mails i recieved that my codes are significantly similar to some others for contest 1930 . I have used online compiler idone.com due to not being at my home . I was unaware of the fact that my code is visible to others . I truely understand that these voilations are not good for the competetion . consider it to be my first and last mistake . I will be very carefull from the next time. Thank you for reading .
S_S_A_231123 is my other account. So, I submitted same code in both accounts. In my account, solution number 235932730 is same with the S_S_A_231123/235934244. . I am really sorry for my actions. I was not aware about the rules and i'm really very sorry of this. Next time I will be careful about this . so please accept my code this time and I will try my best to avoid this type of mistakes in next time
Hex16 is my other account. So, I submitted same code in both accounts. In my account, solution number 235934244 is same with the hex16/235932730 . I am really sorry for my actions. I was not aware about the rules and i'm really very sorry of this. Next time I will be careful about this . so please accept my code this time and I will try my best to avoid this type of mistakes in next time
So , I have got a warning for my solution 233461917 for the problem 1898B which is a famous question asked in Online assessment of many companies like paypal and etc.... The question name goes as Break Sort so for evidence that a coincidence has occurred due to the use of a common source published before the competition the link is https://www.geeksforgeeks.org/minimize-moves-to-sort-array-in-non-decreasing-order-by-breaking-elements-in-two-parts/
My solution 236532458 for problem 1904A significantly coincides with amudalajahnavi/236538566 . I haven't shared my code with anyone but i used ideone.com and I think this is where the problem lies I didn't know that code in ideone is public in default setting. I am extremely sorry this will never gonna happen again.
Same thing happened with me. I will take care next time.
Same happened with me, I was using ideone for my few last contests, I did not knew that someone else can see my code from there, I am really sorry for this mistake. I will take care of this from next, please don't give me any penalties or block my account, I was unaware of this.
Thank you in advance!
The code which I have submitted is written by me it is pure coincidence that it matches to someone others code and I have logic behind my code also, so plz don't erase my all rating****
that was me[contest:1904B] submitted same solution twice.
My solution :- 231159188 for the problem 1895B get plagrism. But the question is very straightforward we just need to sort the array and find the the min and max by applying some condition then how we get plagrised on straightforward question. Please remove the plagrism or read the question and check the solution again manually.
Thanks & Regards
just asking , did you got your ratings back ?
not yet
Hey Mike ! I am writing this message to you in hope you would look into the matter of my code being called plagiarized with solutions which are no where close to my submission and logic. Here is the link : https://codeforces.net/contest/1900/submission/234471374 The questions below this have also been categorized as plagiarized. Please consider this situation. There was a problem once where I used Ideone when I was a newbie. And then I came across those third party rules. I understand the toughness against that and I am not questioning that. But this has happened in the past two contests. Where I have not cheated and I can prove it as well. Thanks ! I hope you look into the matter and consider my situation.

all comments here are — I am not cheating
For submission solution 237521991 for the problem 1905C , I have used IdeaOne for the compiling purpose and I don't know that the code gets public at IdeaOne, This was my first contest to participate in CodeForces. From now onwards I will be careful about my code. Please accept my solutions for all other solutions and keep my rating alive.
.
no
I didn't know someone could see my solution on ide during the contest on ideone and that's the reason I received an email that your solution coincides with others. I will take care next time. Please do not remove my rating. For the submission code 237523833 please look into it, might be a case of sheer coincidence too.
I had posted the code in Python too but was throwing some errors while submitting (no compilation error but was throwing 404) so had to write the code again from scratch which is submission 237523833. Funnily the Python code got submitted just after the C++ one, was frustrated by the system errors, and today the mail, please look into it. Thank you.
Hey MikeMirzayanov , I got a solution siginificant coincide message from the system for the contest Codeforces Round 915 (Div 2) but I literally dont know about how my code matches with any other guy , may be it could happen since I was using an online compiler but I didnt knew it could leak any code or not , It was truly unintentional , kindly look into the matter , my solution 237523245 for the problem 1905C and give my ratings back
why my ratings are not given back to me until now , I said I havent cheated what else I can do , i used online compiler but i didnt knew that was unfair or not allowed , please cmmon give my ratings
sorry , it is a coincidence , i am a fresh man in the codeforces , I don't know why this happened，I promise this is just a coincidence.I'm making a little progress.I released my code in ideone.com.Someone else must have done it.I hope you can return my rating
From codeforces round 916 div3.The problems E1 and E2 were too simple and may be many people thought process can be same for such question.Even I have submitted question in Python 3 and coincide solution are in PyPy.Also I see they declare different variables from mine. Next may system has warned because both the solution of e1 and e2 are same for me and same for other users too. Please give my rating back. I have try hard 2.5 hours and solved 6 problems.
Subject: Clarification Regarding Solution Similarities in Educational Round 160
Dear Codeforces Community,
I want to address concerns about similarities between my solution (237781421) and others in Educational Round 160. I assure you that the similarities are coincidental, and I can provide evidence:
Independent Development: My solution was developed independently, as evidenced by commit history and logic implementation.
No Common Source: I didn't use shared platforms like ideone.com, ensuring code isolation.
Original Thought Process: I can explain my unique thought process in solving the problem.
Can we use Geeksforgeeks code ?
The same happened with me as well I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. Now onwards going to use sublime!Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back

Actually both accounts are mine only(see names as well ntom_ok/vy), I just wanted to check how the ranking changes with the time passed along with the time and memory consumed. I just wanted to experiment. I am going to discard using the other account now. Despite having submitted same code, time and memory was different in both submission. Please remove the violation thing.
i always write code in vs code always i don't know how my code is matching with others . plz help me to sort out this problem .
Hello , How do I prove my innocence? I didnt copy I can prove it I used online compilor programiz and // Online C++ compiler to run C++ program online is even stated above in my code fortunately in hurry i might have forgotten erasing that comment I wrote my code there . in fact i write all of my codes there , Same compilor
Thank you for bringing this to my attention. I want to clarify that I did not use ideone.com My approach was independent. I am committed to uphold the rules of the competition.

Hi Mike! I am hoping to prove that I wrote my solution independently and did not share it with anyone, and I hope that you would be able to help me reinstate my participation in this contest that I did. I wrote the solution 237967879 on IntelliJ independently. My submission was prior to the 3 other submissions, and I had to come up with this solution on my own. I do not know who these people are, nor did I share my answer with anyone as I immediately just went on to do 1914C next. As such, I am not sure how these people may have copied my answer, or perhaps our solutions just coincided because of the limited number of ways to solve this problem.
I hope you could take some time to help me look through this! If there is anything else I need to show to prove that I wrote this answer on my own and did not let anyone else copy, please let me know!

Sir I don't know how this happen but my only one solution out of 6 is matching with only 1 account and I made entry before that person. this may be possible because of compiler or something else. But i write my code on my own and made entry before that account So please don't skip my all solutions from contest.

APPOLOGISE FOR THE MISTAKE ->
I mistakenly used Ideone in public mode without realizing that my solution would be visible to others, and unfortunately, someone copied it.
Kindly Consider my contest rating for the problem 1914C.
I assure you that this mistake will not be repeated again.
Hello Sir, I got a mail about my solution matching with others. I really have no clue about it and evidently it can be seen that firstly I submitted the solution and then that other person submitted. This may be a coincidence. But I am really sorry to say that it was not my mistake at all. You can also check the submission time. Please don’t restrict any rating changes. I’ll try this not happens in future.
Attention! Your solution 238043982 for the problem 1914E2 significantly coincides with solutions _kajol.yadav/238042774, KajolY/238043982. It was an unintentional mistake as both are my own accounts. I mistakenly submitted the code on _kajol.yadav . I then thought to submit the code by my previous account KajolY . It was purely a mistake as you can see my solution of 1914E1 on KajolY that is exactly same to 1914E2 solution it can't be possible if both are not my own accounts. I didn't knew it would lead to this. From next time will keep it in mind. But for this round codeforces please look into this. I didn't shared my solution. Just submitted initially by my other account without realising sorry for this. from next time I will be careful but for this time can you please remove the skipped part from KajolY ID. Codeforces please look into this.
Sorry, but it was a coincidence and I didn't know about it. I published my code on ideone.com that's why the problem occurred due to negligence and unawareness.
I am writing to request your kind consideration regarding the recent coincidence in my solution (ID: 238016088 and 237985408 ) for Problem 1914C and 1914B. I understand that my code was publicly accessible on ideone.com due to default settings, leading to the unfortunate coincidence with other submissions.
Considering the unintentional nature of this incident and my genuine commitment to abiding by the rules, I kindly request your understanding and a reconsideration of my rating for this particular contest.
I appreciate your time and attention to this matter. Thank you for your understanding, and I look forward to participating in future contests with the utmost adherence to the rules.
i have also replied to the mail 2 days ago. Please consider i did not do it intentionally. I was unaware of ideone and also it can be coincidence sometimes the logic can be same. Please consider i will be more careful next time. So request to please consider this once.
I got to know that this violation exists. I use IDEs like OnlineGDB and Ideone quite often and save my code for future references. I sometimes search for reference questions in web to get to know the ways of solving it. I think this lead to the current violation. I sincerely apologize for this situation.
I think someone has a similar template to mine :<
I have no idea how the code is matching. Its just coincidence and I have no issue with any actions but i am not wrong
Sorry for the inconvenience but I have no idea about this. I dont know how much code got copied still I would like to apologize for my mistake and will be careful from the next time.
Sorry for the coincidence I had not known that my code will match with so many people whom i dont know so I kindly request Codeforces to give my rating back .
Hello, My code in Codeforces Round 877 (Div. 2) solving 1838C - No Prime Differences has been flagged for significantly coinciding with these solutions:
208477360 | 208480645 | 208487626 | 208495313 | 208502256 <- my solution
The competition is 7 months old, but I have discovered this violation only a couple hours ago, so I apologize for my late comment. Also I changed my username from Timkador to snalgae, so keep that in mind.
I can remember I haven't copied any code related to the question and I haven't compromised my solution online at the time. I used Visual Studio Code for writing my solution. Obviously, this isn't enough, so I have provided some key points to look into.
Searching for primes. With a low input value to check, making a look-up array for primes is quite reliable. Obviously an array of primes will be available online and it's easily computeable using code. With some cleaning a wikipedia list would fit into the solution. It's also the most certain part of significantly coinciding. The list of primes is pretty large for the size code which could have set off the detector.
The general solution of the problem. Using the sequential order of numbers is possible because 1 is not a prime. And you can order them by row or by column if either of their values is not prime. And for cases with both columns and rows being a prime amount, you can shuffle in a specific way the rows/columns (doesn't matter) to make the differences composite. The solution is simple enough to be independently replicated and in the solutions themselves noticeable alterations can be found. (especially inconsistent is how the rows and columns are shuffled) I'm not sure what kind of source can I provide here though.
Anyways, I hope that this issue will be looked into and resolved/explained. Have a nice day!
Actually I do not have any idea about ideone . I think I turn my ideone public by mistake. I think it was a coincidence .Hope there will be no issue like that further . I will be more careful in future. Thanks in advance.

We are three college friends in same team. We solved problem C together so our logic is same if you want to check you can. For problem A and B you can check our whole code is different. We are new in this platform and we didn't knew about this. So please look into this and give our rating back of hello 2024.
I have used ideone with default settings
I don't know why you guys are skipping me... That's a simple problem so may be many people have the same approach of solving that problem that's why the solution could be the same... I'm completely innocent and didn't cheat in any of the Contents... Please reverts back my rating... And Don't skip me for the for the further contests... I didn't did anything...
But as you guys are saying that using Ideone in default settings is not allowed... I didn't know that earlier I'm never gonna use that ide in future... Please recheck my code is completely different and I myself has written that... Please don't skip me :(
I have been wrongly accused of cheating in a round. I feel I have used generic code with variables from question itself. Please help.
it is really a co-incidence that my code coincides with others ,as i have written my own logic but somehow it matches with someone else logic whom i didn't know.
I recieved this messege
MY solution 241463224 for the problem 1920B significantly coincides with solutions ayuommishra/241445457, Dim_Khichuri/241463224.
& my solution 241484057 for the problem 1920C significantly coincides with solutions ayuommishra/241455008, Dim_Khichuri/241484057
I checked the other solution and find out that the codes are not same however the approch match with each other which is just a co incidence , I am fully sure that i did not copy from anywhere else the codes are mine , its a cordial request to not reduce my rating also not skipping the solves ...

I didn't share my code with anyone or anywhere also I used my own template I don't know how my snipped got match with that much people. I think there is some system bug or misunderstanding. So, I think you should review it and give back my ratings.
I was using the ideone compiler. Same thing happened with me.
Sorry but it was by mistake. I used unpaid version of online compiler replit.com and in unpaid version of replit.com code is publicly visible to others. I didn't knew about that earlier, this won't happen again.
I recieved this messege.
My solution 241784826 for the problem 1921C significantly coincides with solutions jiejiejiang/241784826, pecker/241833220.
I carefully checked my commit and his commit and found that our code was indeed identical, even down to the comments. However, I checked his last submission pecker/241825760, and the habits displayed in this code and the previous submission code (such as the order of header files and the setting of variable names, including whether there is a space after cin) are very similar, but they are exactly different from this submission. It shows that this time he is highly suspected of plagiarizing the code.
Instead, I have the habit of commenting the code under test before committing and other similarities to this code. I'm willing to swear on my character that I typed this code word for word.
To be honest, I was a little confused when I received this email, because I don't know what happened, and I don't know where the default ideone.com(Public access to your code) is set, but I will learn how to set it to prevent my code from leaking again.
Finally, the rating of codeforces is very important to me. I hope my punishment can be reduced. Thank you very much!
PS: The above content is translated from Youdao Translation, if there are mistakes and omissions, please forgive me! Thanks for understanding!
我仔细地检查了我的提交记录和他的提交记录，发现我们的代码确实完全一致，甚至连注释都没改。但是我检查了他的上一次提交 pecker/241825760，这份代码以及这之前提交的代码里面显示的习惯（例如头文件的顺序和变量名的设置，包括cin后面是否有空格）都是十分相似的，但是恰恰和这一次提交不同，说明了这一次他具有极大的抄袭代码的嫌疑。
相反，我具有在提交之前把测试的代码加上注释的习惯及其他方面与这份代码的相似之处。我愿意以我的人格担保这份代码是我一个字一个字打出来的。
说实话收到这封邮件的时候我有点懵，因为我不知道发生了什么，我也不知道默认设置的ideone.com(公开访问您的代码)在哪里设置，但是我会去了解学习如何去设置以防止我的代码再一次泄漏。
最后，codeforces的rating对我来说非常重要，希望能够减免对我的惩罚，感激不尽!

I think i have used ideone in public mode by mistake i had no idea that someone can see my solution there thats why my solution has been copied by somebody. From now i will not use ideone .
damn
I have given the contest of div 2 . I write my code with myself with the variable of my own name and now I don't understand how my code is matched with other code ......
The same happened with me as well I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. I literally had no idea that something like this could happen. I will stop using ideone and just use my local editor. Please don't deduct my ratings.
I have not used the code of someone, their might me stealing of my code because i use ideaone as a platform for running the code.i apologise if at all mistake happen from my side

I got this massage from system,I am very surprised how my implement idea is mathching all of this submission,i swear, i don't use ideone or don't copy code from others.Give me my rating back!!! MikeMirzayanov
The same thing happened to me and I honestly don't understand why, for example, problem A from answer 921, several people can reach the same solution... and because of the intuitiveness of the name of the variables that are generally used in loops and in the strings (generally i, j, s) a code that is too similar to yours may appear without having done anything strange
I don't know why in some way your code for problem A and problem C are too similar to mine....
So disappointed after seeing that I'm skipped from the contest Round 921 . I'm Completely innocent that code was written by me only... And i did not share my code with any anyone. All these variable which i taken are also given in the question itself. Many people can have similar approach of solving a Question. So Please don't skip me from the [contest:Div-2 Round 921]. That's not fair.
The same happened with me as well in Codeforces Round 921 div 2. I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. Now onwards going to take care about all that.
I would like to write about my code matching coincidently with Muskan_Gupta4455 in recent Codeforces Round 921 (Div 2).
My submission id:#243610846
Muskan_Gupta4455 submission id:#243614810
I would like to draw your attention to specific differences in our implementations that significantly impact the final outcome:
I acknowledge the similarities in the logic of the two codes, particularly in the identification of distinct characters within a string.
I would like to draw your attention to some specific differences in our implementations that significantly impact the final outcome:
In my solution[solution id :#243610846]
i = 0; while (i < distinct_chars) { char x = 'a'; x += i; if (char_count.find(x) == char_count.end()) { last_str.push_back(x); break; } i++; } while (last_str.size() != length) { last_str.push_back('a'); }
In Muskan_Gupta4455 submission id:#243614810
i = 0; while (i < k) { char c = 'a' + i; if (freq.find(c) == freq.end()) { ans.push_back(c); break; } i++; } while (ans.size() != n) { ans.push_back('a'); }
The key difference lies in the logic of how the final string is formed when distinct characters are not reached.
In Muskan_Gupta4455 submission id:#243614810 additional 'a' characters are appended until the desired length is achieved, whereas my solution appends 'a' characters only after breaking out of the loop.
I believe this nuance demonstrates independent coding approaches, and my solution (Solution ID: #243610846) was submitted before Muskan_Gupta4455 submission id:#243614810 , as evidenced by the timestamped version history or commit history.
I want to assure you that there was no intention to violate the rules, and I am committed to upholding the integrity of the Codeforces Round 921 (Div. 2).
I kindly request that my rating not be affected, and that there be no adverse consequences such as account suspension or banning.
Thank you for your understanding and consideration in this matter and I look forward to resolve this matter amicably.
Sincerely,
Codeforces ID : Ayush_Sharma_iiitl
About my plag in codeforces 921, I did u ideone as it is more feasible but I did use it in private mode , I don't know how It got leaked or something like that. Anyways I promise I wil not use it again .
This is with regard to the mail plagiarism for the problem 1925C,
I want to tell you that I was using ideone for a long time but this had happened to me for first time. i don't know about that public setting. i will assure codeforces that it will not occur again in future. Pardon me for the unintentional mistake I have caused to this platform and don't remove me please.
I think Codeforces should have an appeal channel so that people don't need to stack there appeals up here, which is meant to be a declaration of the third-party code rule
MikeMirzayanov please consider this thanks
hello codeforces, i had a message after Educational Codeforces Round 922(Rated for Div. 2) .which says that Your solution 244071161 for the problem 1918A and solution 244107695 for the problem 1918B significantly coincides with solutions of account of adarsh_1234 and srijanraha .i want to say that both of the accounts(adarsh_1234 and srijanraha) were mine and i am a begineer so i don't know the rules of submissions . But i promise that the soutions of both accounts is completely mine, and i won't make this mistake again.please remove plagarism from account adarsh_1234.
Please return the ratings
Both the accounts are mine. I created this new account temp_error to see the rating increase in the codeforces. Therefore, I submitted with both the accounts in codeforces round 922 div 2. I never knew that it is unfair(as both the accounts are mine). Please forgive me and its my guarantee that this will never happen in future. Please deduct the rating from account.
I wrote my code using ideone.com in public mode, without noticing it. When I received messages that my code was a copy of another one, I simply did not pay attention, unfortunately. Now that my rating has been lowered by almost 2 times, I paid attention to it! Please return my rating and I will switch to another IDE (this will not happen again).
sorry my code matches just by coincidence , i did it ideone.com compiler so there are chances someone has copied it and i was not aware of it. please give back my ratings. I wasn't aware that others can see my code , i'll not repeat the same again.
I want to convey my issue for the mail plagiarism for the problem 1918C,
I didn't know this would happen as I am using ideone for a long time but this had happened to me for first time. The public mode is by default in ideone so, I didn't know about it.I will assure codeforces that it will not occur again in future. Deeply sorry for the unintentional mistake I have caused to this platform and don't decrease my rating and don't remove me please.
I am Extremely sorry and i am not aware of this rule and i did it in ideon since i was travelling and here i by i declare that this mistake will not be repeated please do retrive my submissions
244133701 I unintentionally used Ideone in public mode during the contest and wasn't aware that others could view my solution. Unfortunately, this led to a collision with another participant's solution. I apologize for any inconvenience this may have caused and will ensure my code remains private in the future by using Sublime
My solution 245220534 the template of LCT came from https://www.luogu.com.cn/paste/2f08n2gp ,and it is my own template and was posted in on 2024.1.29.Please give my rating back,Thanks!
Man, the main part of your solutions looks almost the same (245220534 245224986 245203918).
Should I continue?
Hi, I received the message that my solution 245178149 of problem 1927D (245178149) is similar with 245229382.
I claim that this solution belongs to me. Anyone can see that template functions is written by me and exist in my previous submissions. The user thelostpirate, I don’t know how, received and, a minute after submitting his solution in C++, submitted my solution in Python. This looks very strange. Please, take your attention on this and unblock my results of contest 1927.
After thinking a little about how my code could have gotten to another person, I realized that I had committed it to GitHub. And it’s surprising that the commit time is 1 minute earlier than the thelostpirate's submission time.
Ah, unintentional leakage is also a rule violation. Ok, I'm sorry. I Didn't know that rule and that such leakage possible. I will no longer commit to GitHub until the end of the round.

I didn't copy the code from anywhere I just use same approach on Two other questions on Leetcode or gfg and i think these questions are very popular so thats why everyone just go through this approach.Please look into it fairly @MikeMirzayanov
My solution 245204540 for the problem 1927D coincides with solutions of few listed people.It is actually a co-incidence that my code and my logic is similar to others code as i had solved the question with my own logic and compiled it in my laptop and not on any online platform and didn't even upload it anywhere. Might be my code writing style is very generic and you may compare my codes with other codes too, you would find similarity among them. I hope this all is a misunderstanding and I request you to unlock my previous contests scores.
This submission in round 923 Div2 problem D was flagged as cheating though I didn't cheat https://codeforces.net/contest/1927/submission/245203647
Hi
The similarity between my solution (245215603) for problem 1927E and those of other participants. I want to clarify that any resemblance is coincidental and not a deliberate breach of rules.
The simplicity of the problem likely led to similar approaches. Additionally, my coding habits, influenced by the Algozenith course, might have contributed to the resemblance in style and structure. Furthermore, I used an online compiler, which could have contributed to similarities in implementation due to default settings or common coding templates. There is also a chance that some students at my college might have got access to the code due to unsecured wifi.
I assure you of my commitment to fair play and integrity in competitions. There was no use of unauthorized resources or intentional plagiarism.
None of my solutions have been flagged till now also. I request the team to review my code again.
Yep i used ideone in public mode .. what should I do now ?
Make sure you won't use ideone in public mode next time.
Codeforces team please i solved problem E myself hundred percent .. how can i cheat in c ?!
Dear all,
Today I was accused of violating the rules of participating in the latest Codeforces Round. Specifically, the system detected that my solution C coincided significantly with Amrharb's solution. The submissions are presented below.
245832569 — Amrharb's solution
245842883 — my solution
While it might be true that the solutions are slightly similar (because they build up on the same mathematical idea), the style of writing code is significantly different. Most importantly, I have never known Amrharb, therefore I could not have "copied" the solution. In addition, I did not use online compliers like Ideone or Pastebin, and, most likely, neither did Amrharb.
I am therefore asking to drop the accusations of cheating. If the evidence is not convincing enough, then it is, in accordance with the rules, necessary that a punishment should be applied to my account, which, obviously, would be quite unfortunate.
Sincerely,
Fiodar Prystauka (jV_)
You have been accused by the system due to your past violations. Upon review, we have concluded that the accusations are false, your rating for the round will be restored.
I appreciate your swift action. Enjoy your day!
In Codeforces round 922 problem C. I used online IDE and I was not aware of this that it was in Public domain. Please give back my main account Alok20, I will make sure that it never happens again.
Hey Codeforces[contest:923], I did used Ideone as well and will never do this from next time. I did not knew it was default by public so I request the administration to please look after the issue regarding my contest rating as I don't have idea that someone can see my solution on ide during contest, that's why i received a message that your solution is collide with others. I will take care from next time.
Hi, I'm replying to the email sent to me by the system: "Attention!
Your solution 246212767 for the problem 1931E significantly coincides with solutions Byee_bobu/246201807, balandior/246212767. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).

for compiling I only use CLion, I don't post on ideone, I have never received such a message and think that it must be a coincidence as I have no connection to the other person, the algorithm is pretty straightforward and yes even though it could be written in multiple ways I'm pretty sure there will be other submissions with the same code structure but different details, so this kind of match is possible, which is what must have happened as I haven't leaked any code.
thanks for reviewing my comment, I hope that everything will turn out to be fair for you.
Sorry for the inconvenience occured .I just tried in ideone in default and someone copied the code.Its my mistaken and for It will repeat again
I didn't know code written on ideone was public by default, as I was using it for the first time. I will be careful next time. Please forgive me, this will not happen again.
For the contest 925(Div. 3) when I tried to run my solution in custom compiler it didn't worked so I used another compiler named ideone. But today I got an email stating that My code matches with two of other contest participants. But it is a mere coincidence. I had not any knowledge of the public or private mode in ideone.
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem may be occurred. Believe me it wont repeat again. Kindly give back my ratings as soon.
In the given contest the codeforces compiler does not work properly so i publish my code on ideone.com. so it a coincidence my code match with other person so sorry for this. in feature this mistake is not occurred so please give me my rating.
I did it in ideone complier in public mode I think some one copied it please consider my request
Hey Codeforces[contest:923], I did used Ideone as well and will never do this from next time. I did not knew it was default by public so I request the administration to please look after the issue regarding my contest rating as I don't have idea that someone can see my solution on ide during contest, that's why i received a message that your solution is collide with others. I will take care from next time.Please excuse me this time.I wont repeat it again
i used ideone in default settings
this was my first time using ideone, please consider my request
I had by mistake use ideone.com ,and unfortunately my code is available in public mode and someone copies it.
I see, your A and B submissions are in C++17. And now you happen to submit C in C11 ? You want me to go on?
CHEATER!!!
hey bro i know multiple language I also do comppetive programming in python also, i mainly do competive programming in c,c++ and python. So before calling me cheater look at yourselff.
Why did you even submit in C? All of your submissions are in C++. Did you forget to change it from C to C++ when you copied it from telegram? Maybe you don't even know C, so you wouldn't know meaning of all those scanf, printf.
Bro do you know that some problem are easy to implement in c some are easy in c++ and some are easy to implement in python,and i don't think so codeforces hadn't allow me to submit in different language,is this is the codeforces policy,i don't think soo.
And talking about copying the code from telegram ,bro wake up and what you said i had forgot to change it in c++ and i dont know the meaning of scanf and printf bro those student who know c++ they very well know what is c there in not much diff in c and c++ only the diff is of the oops concept which is there in c++ so common broo wake up this is the gltich of the codeforces
Why don't you show us the mail you got? Let's see how many people copied your solution from ideone.
)
Can you edit your comment and copy paste the mail, instead of attaching screenshot? That'd be helpful to check your case manually.

U can check this out i dont know earlier about posting the gmail screenshot that why i hadn't posted now u can checked this out
"Hey, what are you talking about, are you kidding me? I came up with all the questions myself, yet I received the same email. I don't even know the people I matched with. How would you explain this?"
In default settings i had use ideone please give my rating back!!! MikeMirzayanov
Well this submission was sent 12 minutes before your submission. Now convince me that he copied your solution before you even submitted.
whatt this is happeningg brooo thousands off people give the contest and many moreee logics can be samee andd if we talk about the variabblee what else we should take ,if we talk about the first question this contest this question is pretty straigt forward and easy u just had to sort the vector and implement the mechanism given in the question this approach is done by the thousand of people so will codeforces will give all of them palgraism,this is the method of giving palgarismm and i am not noob in this i will directly copy the whole question i will made further changes because i had half an hour left for this to do this stupid things , in this contest many more had faced the same problem what wrong with the codeforcess.
Not all questions are checked for plagiarism, codeforces isn't stupid. They check only those problems whose solutions are not so obvious. You got plagiarism on C problem which you copied from somewhere. Explain to me how your C problem is similar down to variable names. And no, Mike doesn't listen to any pleads here.
In the question we have given varible, k,x,a that's why i take this varable name even every body does take this name
arr u sure codeforces is not doing stupid things? if in the question it is written a,k,x so we will take a,k,x only na why we should change the varriable name that is givine in the question of thinking others.Bro wake up to reality and why codeforces is not checking the easy question ?? that question can also be copied from other....
You guys know you cheated, accept it and move on. And rahul_iiitr, there's no point of changing variable names as it doesn't matter. Plagiarism is checked by comparing your code's logic. If they are similar more than x%, then your solution will be skipped.
Easy questions aren't checked because probability of coincidences rises exponentially in them because of short and obvious solutions.
broo common i am explaining mine you give me the obviouss reasonn means genrally codeforces are checking the logic of question and by matching codeforces is giving the palgarismm what the stupidy is this 3rd question is not that much hard question that this solution is not obvious so we are always in the fear that is there any code which are applying the same logic we should be in the fear then....
I'd like to assert that there is no plagiarism involved in my recent contest [problem:1929C][contest:1929][user:]submission. My coding style remains consistent across all my submissions. I consistently use the <bits/stdc++.h> header file ,Regarding the consistency in coding style, the indentation, variable naming conventions, and overall structure remain the same across my all submissions. Additionally, I'd like to highlight that my thought process and logic for solving problems tend to be straightforward and simple. In this specific problem, for instance, my approach to the betting case involved predicting the outcome of the next bet based on the current situation. I calculated the next bet by considering the current loss and the multiplier, and then determined whether the opponent could recover from their losses. Here's a brief explanation of the code: The function
next_betcalculates the amount to be bet in the next round based on the current loss and the multiplierk. It ensures that the bet is always rounded up. In themainfunction: The number of test cases is read into variablet. For each test case:k,x, andaare read, representing the multiplier, the number of rounds played, and the current total loss of the opponent, respectively. A loop runsxtimes, representing the number of rounds played. In each iteration: The next bet amount is calculated using thenext_betfunction. The total losspis updated based on whether the opponent wins or loses the current round. The loop continues if the opponent's total losspis less than or equal toa. Finally, it prints "YES" if the opponent's potential total loss after the next bet exceeds their initial lossa, indicating they cannot recover, otherwise "NO". And you can take the reference of the tim stamp and my continous trail on this question for almost 25 mins and then submitted after a lot of corrections...During contest othere than Coding companion which is used for test cases i firmly confirm that i dont use other external 3rd party apps , links or extensions. I believe in writing clear and concise code, focusing on simplicity and readability. It might be coincidence or whatever and i beleive there is another problem in codeforces named "playing in cassino" which i took reference from before the contest so i beleive this is not a palagarism and definetely coinciding with these many submissions seems very suspisous of my claim but i still claim my thought thank you!!bro had u also got the same mail that i had gott,i this contest many of facing the issues butt we dont know what approach someone else is using ,there are thousands of student giving the contest and talking about the 1st problem of codeforces that question logic is same forr all of them so codeforces will give palgracism this not the right policy i think so .This is the very trusted competive programming platform they had to fix this.
yup
this is not okk , many mare are facing the same pronlem
****I just received an email stating that my solution significantly coincides with the solution of many people, but I used my own concept, so why did I receive this email?****
Respected sir, This is regarding my recent contest in which I recieved a mail about solution: 246562099 and 246553271. I want to inform you that I am an inncocent person on this case. I usually solves code in Online Compilers like ideaone.com and onlinegb.com. Due to which my code got leaked and I did'nt knew about that. Here are my images of proof: Your text to link here... and
Your text to link here... I request you to please consider this as a problem and help me get my innocence back as soon as my possible. I promise that this wont't happen next time, I will use private compilers.
Thanks and Regards Nishkarsh nishkarsh1215
In your problem C screenshot, your stdin and stdout is empty. How were you testing your solutions during contest? In your mind?
This proves that you pasted solution to ideone after you got caught. There's no point of pleading here now. Don't even reply to me if you have stupid justifications for it.
Have you tried edging?
Seems like you love to edge, even most of your comments are related to edging. Or probabaly it's the love of contributions?
You even got almost 100 likes from edging here. It's doing wonders for you. Are you edging right now?
I think i have used ideone in public mode by mistake.
That's why the problem occured.
Sorry for my mistake.
I got a message saying my solution 246533687 significantly coincides with 246548241. Looking at both submissions I believe this is because of the stdin parsing template. I originally modified the code from this blog post, and the other user copied it, probably from looking at previously submitted Rust solutions. Other than the stdin parsing code, the solution code is not the same. I think this is a false-positive due to the low number of Rust submissions.
I don't know rust, but your case seems legit to me. A Comment here will go unnoticed by authorities, I'd recommend you to make a temporary blog about it and tag Mike. And hope for some magic.
Don't forget to present your case in short and crisp manner, and link your comment in blog so people know that you pleaded here too and won't blame you for posting a blog about it.
I used the IdeOne to write the code in the contest and which one was set to default and most probably that's why it happens. By the very next time I will keep this in my mind! Please don't skips my submission
Sorry! I have used ideone to write my code while contest that's why this happes this happens. Please don't skip my solved questions! I will keep it mind by the very next time
Recently I have Participated in the Codeforces Round 927 (Div. 3). My solution for this problem problem: (C) LR-remainders has been marked for coincidence with the other user. I have used the ideone java compiler with the default settings and unfortunately my code is copied by someother user. After reading all the rules , Now I understood that we should maintain that settings to private. Please excuse me for this time,I will make sure this will not be repeated again.
I don't have idea that someone can see my solution on ide during contest, that's why i received a msg that your solution is collide with others. I will take care from next time.
Please give my ratings back
You already have your rating, tf you talking about?
but questions attempted showed skipped WhY??
I learned the algorithm for sum of digits of n numbers from geeks for geeks and used it to solve the problem 1930B. So it’s maybe a coincidence that my code is similar to the code of 2 other users. I apologise for that and assure that I will make my code more othentic in the future
Just stop cheating:
MikeMirzayanov I agree that he cheated as those submissions are clearly same.
But I can see that this problem is really simple, just return sum of non-overlapping adjacent pairs after sorting. This has a really high chance of false positive. Even tourist has same solution. Therefore about 1000 users got skipped in A solution. Correct me if I am wrong. Or maybe you flag only those submission whose similarity is really high in this problem. IDK.
MikeMirzayanov Hello sir. My Codeforces account (handle:10_Not_Found, email:[email protected]) had been disabled for many days for breaking the code of conduct in Codeforces. I apologise for this misconduct. Next time, I will be more careful about this, and I assure you that this misconduct is never going tobe happened. Please, sir, accept my apology and enable my account. Thank you.
I think my code has no problems,but why skipped? I don't know why i copy others ,i don't know him
I tried running my code on ideone in default setting (public mode) and someone copied my code. I was not aware about that.I will never run code on it from next time sorry for the violation of guidelines.
hi codeforces team i want to tell you that i done first four questions of think cell round 1 contest, but i saw my responses today and i found that all my solutions got plagarism by your team. you can definetly see my all previous submissions and you know that my coding style is same. Please take action on this as soon as possible.you can check through given link
First of all.... problem D was not that easy to be solved by a beginner .... Secondly When you wrote the optimised code for D, then why you haven't submitted that in D2 ?? Because you don't know the complexity and not even know the problem D I can challenge.
Stop Cheating and behaving like you haven;t done anything wrong.
I request MikeMirzayanov to ban these kind of people from codeforces. CHEATERS FOREVER
In pace of doing more questions I copy that D problem from my friend. But why you skipped all my previous three submissions. I done that problems myself. Kindly check my that problems submissions. I am new to this platform but I done many problems on other platforms.
If you cheat, the contest gets unrated for you. Hence all your submissions are skipped. This is how it's done on codeforces. Repeated violation will get you banned too.
But i saw many others submissions they got skipped on 1 or 2 two problems, and not gets unrated so why my whole submissions got skipped, please verify it...
This is the chronology.
These times are completely dependent on CF Team, and can vary.
so can you please rate according to my genuine submissions in the contest...
sorry for this i was not aware of that, i am beginner i was having some problem and i google it unfortunately i forget to delete the comment on code sorry for this will not happened again

Hello, I got this message from System
Attention! Your solution 246877670 for the problem 1930D2 significantly coincides with solutions Chrisedyong/246877670, Palestinian_Dream/246884367, lokoboko/246885814, Aang__/246886178, Ari10/246888338, baqk/246888355. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

In case of repeated violations, your account may be blocked.
I did not use any online compiler at the contest. I did not communicate with other participants during the contest. I developed the solution by myself without cheating. This is false positive and literal coincidence that the solution was same. The same solution dynamic programming flying table could be developed by other participants during the contest. Please MikeMirzayanov investigate this as I believe this is a coincidence. My submission link: 246877670
It seems like your solution was leaked by someone in your hacking room. Your submission was first and you have no history of cheating, therefore your solution wasn't skipped, and you were released with just a warning.
How to prevent leak code from hacking room? If it gave me a warning, then I need to take action (may be if I can) so that my solution will not leak again in the future.
I don't think there's a solution to prevent your code from being leaked from room. It's a vulnerability and cheaters take advantage of that by leaking your solution without leaking theirs and earning money.
The only way is obfuscating your code, but even that is against the rule. So, just hope that no one does it.
Thanks for your feedback
This has happened in past too, like this and this.
Mike said in case 1 that the user didn't get punished just like you. But I'm not sure what will happen if your code gets leaked again. How many warnings are given in such cases. But I am sure that there's a limit to it, otherwise anyone can leak their own code and won't get plagiarism, instead others will get caught.
You can write a lot of templates or #define to make it difficult to copy ):
Writing a lot of templates and macros don't matter as
void solve()andvoid main()functions would still be clear to copy.Unless you are talking about changing our habits to write codes using macros itself, like this. But this is still possible to copy as logic is clear, and macros don't prevent us from plagiarism.
please don't give penalty, it was an mistake. give me last chance
.
I tried my code in running ide,unknowingly I think it has been leaked. → I make sure that it won't be repeated again and I take care of every thing.
I am really sorry if you find anything misbehave, but I have done the code myself, and I have used ideaone platform in public mode, because of it some one might have copied it , I will definitely take care of it from next time so please give my rating back as you can see my past contest history I have never tried to copy or misbehave during the contest,And I promise you I will take care of keeping my code private during the contest.
Recently my code for problem f in Codeforces Round 928 (Div 4) was flagged as a plag with @Electric_Dragon's code. This is a false accusation. The solution has a simple straightforward Brute force approach, and any similarities in our codes were purely coincidental or in the matter of fact no existent at all. I haven't shared my code with anyone, nor have I copied it from anywhere. Admins please reverify your plag claims, as this has caused a great deal of fall in my ratings and points.

You left a comment 2 years ago too.
I was using Ideone for the first time and didn't know about the public option I completely agree that its my fault please give me my rating back it won't happen again. I found it on Reddit and it was my first time using it I assure you that it won't happen again. please consider this time and won't happen again will use a local ide..
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occurred. Also I have made the submission before @Nova_042, please look into this as all the questions in that contest has been solved by me only. I assure that this will never happen again. Waiting for the response at the earliest.. Thanks :)

for my 247332527 on div4 1926F with. I do not know the people in the message and didn't cheat. Consequently, I think it false positive. The submission before me is a java code by snehi 247323008, while mine is c++. Other codes in message, are also java. I wish this appeal to bee seen. Idea or motivation into the bitmasking complete search for black subsets maybe similar. I think implementation differs.
I wasn't plagiarised before, and even had similar performance solving 7 in div 4 on round 918 (Div. 4)
Thus, I am asking to drop the accusations of cheating. If the evidence is not convincing enough, then it is, in accordance with the rules, necessary that a punishment should be applied to my account, which, obviously, would be quite unfortunate. MikeMirzayanov flamestorm mesanu SlavicG Vladosiya

Your solution 247285175 for the problem 1926C significantly coincides with solutions JonahWeaver/247270977, arnavra3/247285175, Jelly.bean/247290520. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
I have evidence that the function that i have used for the question https://codeforces.net/contest/1926/problem/C was already published long before the contest.
The coincidence occurred due to using the same function to solve the question. (coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details). This is the function used to solve the question- https://www.geeksforgeeks.org/count-sum-of-digits-in-numbers-from-1-to-n/
Thanks for your time and for looking into this.
Codeforces Round 928 (Div. 4)
For the question https://codeforces.net/contest/1926/problem/C i received this message:
Attention! Your solution 247351936 for the problem 1926C significantly coincides with solutions sntanju07/247303669, Rafid_Nabil/247351936. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).

In case of repeated violations, your account may be blocked.
I have proof that the code that i have used in the solution already existed even before the contest. I have used two functions in my solution which i got from this link: https://www.geeksforgeeks.org/count-sum-of-digits-in-numbers-from-1-to-n/
This are the two specific functions that i have used in my solution:
int sumOfDigitsFrom1ToNUtil(int n, int a[]) {
if (n < 10) return (n * (n + 1) / 2); int d = (int)(log10(n)); int p = (int)(ceil(pow(10, d))); int msd = n / p; return (msd * a[d] + (msd * (msd - 1) / 2) * p + msd * (1 + n % p) + sumOfDigitsFrom1ToNUtil(n % p, a));}
int sumOfDigitsFrom1ToN(int n) {
int d = (int)(log10(n)); int a[d + 1]; a[0] = 0; a[1] = 45; for(int i = 2; i <= d; i++) a[i] = a[i - 1] * 10 + 45 * (int)(ceil(pow(10, i - 1))); return sumOfDigitsFrom1ToNUtil(n, a);}
Due to the use of a common source https://www.geeksforgeeks.org/count-sum-of-digits-in-numbers-from-1-to-n/, the coincidence has occurred.
Please look into it
Thank you
Am i misunderstanding the rules? What did i do wrong?
MikeMirzayanov please look into the matter
I don't understand this way of judging. Using the same method but not the same code is also an error. For an obvious template problem, can't you use an existing solution? Because of this way deduct my two div points, I said maybe I will choose to give up to continue to participate.
I have recieved an attention for the problem https://codeforces.net/contest/1926/problem/C of Codeforces Round 928 (Div. 4). The message was here. Attention!

The code I have used from https://www.geeksforgeeks.org/count-sum-of-digits-in-numbers-from-1-to-n/ which was last updated on 27 Jun, 2022. That's why, I can prove that the code exists before the contest. The coincidence occurred for using a common source.
Please consider it. Thank you.
Sorry but I think you're wrong .I didn't copy any code and also not share to anyone. I'm regular user of codeforces since 2 years before.
Subject: Request for Reevaluation of Codeforces Submission for round 926 on 15 th feb
I am writing to address a matter regarding a plagiarism detection notice I recently received for my submission on Codeforces dated February 15th.
I wish to emphasize that the code under scrutiny is a product of my independent effort and original thinking. At no point did I resort to copying or sharing the code with any other individual. It is a manifestation of my personal logic and understanding of the problem at hand.
Recognizing the significance of maintaining the integrity of the platform, I acknowledge the seriousness of plagiarism allegations. However, I believe it is essential to consider the unique dynamics of Codeforces, where submissions often tend to exhibit similarity due to the concise nature of the codes and the common programming techniques employed.
Hence, I respectfully urge you to undertake a thorough reevaluation of the plagiarism detection notice attributed to my submission. I am confident that upon closer inspection, the originality and authenticity of my work will be evident.
Thank you for your attention to this matter. I remain hopeful for a fair and just resolution.
Sincerely,
Lahari_Betavolu
i m sorry for that please consider this request i have not used code from any platforms or copied code from others
I have 2 questions for people with experience of exposing cheaters: 1) How much contests need to be skipped for person to get a perm ban? 2) When you exposed cheaters, did it work? Were they banned? So I've recently stumbled upon an annoying cheater who has alredy cheated in 8 contests and he has no remorse for what he did. Also I have a legit prove that he messaged at least 2 people during the contest asking for solutions. Moreover, it's also pretty obvious that he cheated in round 927, but didn't get skipped for it. So what should I do? Should I expose him, will it have any affect on him?
1) Permanent ban takes around 5 skipped contests (Completely skipped).
2) It is not that immediate that they are banned but if you provide concrete proofs they can get skipped, even on some specific problems from the contest (manual skip not system automatic) To be banned check (1)
If you have concrete proofs, similar submissions, then go for it! A proof with messaging during contest especially if he used codeforces messaging would be certainly enough.
Should I just mention messaging or show photos? For clarififcation, he messaged people on cf
.
Please, stop chat gpt. Be original in your appeal at least.
i have written my own code and i can strongly say i didnt copy it from anywhere .And i didnt share or copy code from anyone i got plag with . my account handle name manish243 got blocked this may impact on my academics also please consider my request. please unblock my account

I recieved this message from System Attention! Your solution 247919274 for the problem 1923C significantly coincides with solutions:

I mentioned the submission of the first 4 person that were mentioned in the message ..but there are alot of people that were mentioned in the messsage..
-if you look at the fist 4 submission ..their code is very similar ..they are using function called (buildsparse) and another called (query) to use sparse table .and I didnot use any sparse table in my code...and I didnot have sparse table in my templates too.. they are using function called findCount..
.my code is really different .. I used vs code and I didnot use ideone before ... MikeMirzayanov
I suppot, sir. Quite unfortunate. False positives might happen as the plag system is strong.
I'm on your side man.The following four submissions are almost the same and yours is different from them.
i usually use sublime text editor but lately it take lot of time for compilation so i use gdb compiler. that might be the reason the our logic is same.
hi, MikeMirzayanov
The submission 248614816 and 248610222 of 1933E - Turtle vs. Rabbit Race: Optimal Trainings- are just coincidences
I am sure I didn't copy the code or send it to others.
Obviously, we have the same idea of this problem, and coincidentally, our code styles are similar.
I have no reason to send my code to others and cause me to be skipped.
So I just have the same idea and similar code style with a stranger coincidentally.
Thanks!
The fact that you have almost identical binary searches as functions hidden inside the huge template makes it kinda suspicious...
Also, the use of two binary searches, which always find adjacent positions, looks weird and has met among many cheaters.
-
You are the one who submitted later and didn't change his specific template...
248618474 248617752
won't happen again
Hi, MikeMirzayanov,
My submission of 1933E — Turtle vs. Rabbit Race: Optimal Trainings- 248614142 has been wrongly flagged
with 248626407 and 248628054. As you can see my code is totally different from the other two Although our coding styles seem to be similar. Neither do I know the other 2 persons nor have I used Ideone or any other online IDE. Hope its rightfully judged.
Thanks!
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody in problem 1933E and problem 1933D.
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody in solution 248624355 for the problem 1933E and solution 248583560 for the problem 1933D.I will take care of it next time.
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody in solution 248961215 for the problem 1937B .
Hi MikeMirzayanov,
This is just a mere coincidence that my solution here https://codeforces.net/contest/1933/submission/248628644 is matching with Xnbinj/248608302, Devanshu-Sharma/248609258, person_31/248610293, YOUR_SUPERMANnnnn/248610791, bokoharam/248611919, straw_hat_luffy/248611948, Hamza_sf/248612769, Aniket_1087/248617971, radheKrishn/248618216, xiaoran_/248619479, akkinani1211/248619660, arpan2048/248619787, EducationalCPer/248620054, zhdanovich/248621160, adi654/248621610, ok_code/248622279, mdalm0025/248622987, -0_0-/248623123, theNumb/248623276, noob_tdbs/248623555, rahult724/248624420, kiso_hbena_amkdie/248624919, Mysterious_Queen/248625905, dedhooma.xd/248626270, LD-RW/248626818, K.Yusuf/248627402, yuerubaiwan/248627669, Snaha_Fency/248628301, cold_cookie/248628528, thelostpirate/248628644, backupofz/248630153, parth89/248631296, drifter_kabir/248631992, shubhamranswal/248632301, a01h/248632484
I don't use ideaone anymore or any other platform for the same and my other solutions can be checked to verify that. I understand that I have used ideaone in the past and that might be a reason why this solution of mine is flagged. But it hasn't been the case this time.
Hi i have recieved a plagarism alert on 1937C please look into the matter my codde is significatnly differnt from the what mail has mentioned as being similir from. I don't know is it due to similar temeplate or something please tell me what proofs can i offer.
I don't copy anyone code & i also analysed the code of shaon508/248606418 . I found there several logical and initialitation different. Why codeforcses plagiarism check method marked those are similar i don't understand this. If codeforcses will give me any kind of penalty than that is a very worse decision . Also that upset me.
This round was start on Tuesday, February 27, 2024 at 20:35UTC+6( Codeforces Round 929 (Div. 3)). Round had 2 hours and 15 minutes to solve 7 problems. This round were authored and prepared by erniepsycholone, snowysecret, dbsbs, jerryliuhkg, lomienyeet, and our beloved coordinator Vladosiya.
I suggested codeforcses that you should change your plagiarism check method . Otherwise if you take a worse attamp against a coder that is harmful for him/her.
I am very sorry for the coinciding solutions, actually both (priyanshusinghp0220/248947920, Pr9yanshu/248957372) are my handles and by mistake i wrote same code for both handles. Although I have deleted the google account with this handle(priyanshusinghp0220), So, please , do not unrate my contest for Pr9yanshu. This will not happen again in future.
I don’t understand why my submission is skipped.I don’t copy anyone code.I view jabir_joyed9494/248612776 submission,there are many visible difference like logical and structural.I suggest codeforceses to recheck it and give my points back,otherwise it is a very bad decision.Codeforces Round 929 (Div. 3).This round was start on Tuesday, February 27, 2024 at 20:35UTC+6.

Even you copied his comment too, which he copied from chatgpt xD come on, at least you should have written this small paragraph on your own.
i write it into docs..........then check in chatgpt (look time also)
don't judge other
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured.I use ideone. I was not aware of this. Please don't block me or give penalty as I do not know about this.
I will be aware of it next time.
The same happened with me as well I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. Now onwards going to use sublime!
Codeforces Round 929 (Div. 3) I received a notification from codeforces stating: Attention! Your solution 248603055 for the problem 1933B significantly coincides with solutions Chethana_14/248603055, sanjana_sanne/248608339. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).

I'm really disappointed to find out that I was skipped from contest Round 929. I compared my solution with other and noticed similarities in approach, and our coding style is similar. It seems like we just happened to think alike. I have no reason to share my code with others and risk being excluded from the contest. I'm confident I didn't copy or send my code to anyone. It's frustrating to be skipped when I've done nothing wrong. I assure I'll be more careful in the future. Please refrain from imposing penalties or blocking my account.
even not copied the code then why system sends me message of plag, codeforces nned to work on their system.
it is a coincidence because i have not shared my codes with anyone
it is a coincidence because i have not shared my codes with anyone
Truly speaking both the submissions coincided were from my own account, I did not know about the policy. I swear both were my accounts, you can check from the user ID as well and I swear I won't make the same mistake in future, please pass the verdict of those questions and don't take my ratings.

Hi,this may be because of using common platform named ideone,I'll take care of it from next time.
The issue of violation of rules have occured because as we have same ideology to solve the problem so the approches to solve the problem of klu_2200030907/249814526, klu_2200030883/249823570 are same. Please consider the issue is true and genuine and please give the rating back and i assure of not repeating it again.
Sorry but it was a coincidence. I published my code on ideone.com, This is may be the reason for this. So please give my ratings back.
I have clearly not copied for problem 1937B. This is a clear coincidence. I had tried the question for a long time but was unable to solve. With a different approach, I tried the solution which I used, for a long time, after which it got accepted. I am not sure who the other person is but I am very firm about the fact that I haven't indulged in any kind of malpractice. Also I do not use any public compiler for coding so there are no chances of leak. I would request you to please look into it. Thanks !
Hats off to the setters of last div3, kinda difficult B for its position but it caught cheaters xD
edit : skipped in Div2, Binary paths not last div3, but still same point holds for both contests
I tried running my code on ideone in default setting and someone copied my code and I was not aware about that
I have been using ideone for my all contests, I did not know that someone else could see my code from there, I am really sorry for this mistake. I will take care of this from next time, please don't give me any penalties or block my account. I was unaware of this. I assure this shall never ever happen again.
same thing it happened in my codes too and don't know why they send notises to me ??
...
hey ! i received a mail from Codeforces that 2 of my solutions from Contest 932 coincides with 4 other contestant's code but i didn't copy or discussed or shared my solution with anyone. Can anyone tell me what to do next ?
I got this message from codeforces that my code for the problem 1941E coincides with many people ..
I did not cheat and so I wondered how is that possible, so when I checked for their account and their submission fact is I did not see any of them submitting any solution for this problem some accounts did'nt even exist although I check a few.
There has to be a error or Am I missing something?
I dont't know but help me community regarding this.
I am using this "https://www.programiz.com/cpp-programming/online-compiler/"
This guy got skipped in 6 contests. Why isn't he banned yet? Heap_OverFlow, do you know the threshold for automatic ban? (Sorry for tagging you, I need answers)
1
2 
3 
4 
5 
6 
Np. I don't see he enrolled in many contests so I guess 6 is more than enough to be banned. But I had previously seen a BAN after 9 skipped contests, but had enrolled in like +70 contests.
I've seen accounts getting banned under 5 skipped contests. And now you've mentioned that some gets banned after 9 contests.
I don't like that codeforces doesn't clarify so many rules. Is banning manual or automated? If it is automated, is it absolute or relative? Absolute means getting banned after x contests. Relative means after a proportion, like (skipped contests/ total contest).
Logically, as banning is a strict move, it is possible that it would be manual.
Yes, I saw banned after 5 contests too.
Most probably, relative. Like the one banned after 5 contests had 12 contests in total. The one banned after 9 contests had 74 contests in total. Yes, it can be manual sure and more related to warnings(for instance, if you leaked the code or toxic social content) than skipped verdicts
Yeah, that makes sense.
Hey architect_, would you mind updating us when you get banned so we can figure out the relative proportion?
But wait... how will you do that?
Anshul_Johri ok I accept the mistake,I cheated for 5th q and will not do it again Now I am not saying this because I don't want to be banned or something but I realized that if I can do 4 q's(div3) on my own I can do 5th too in some time. thanks
That's good. If you know you're good in coding, you'll be better doing it honestly than cheating.
My advice: Don't care about rating. Focus on practicing. Even if your contest is going bad, you might have urge to open youtube/whatsapp/telegram but resist it and you shall feel proud of yourself. Even if you lose -60, you'll gain it back in next few contests. A coder can never reach top standing with cheating.
I wish you all the best in your honest CP journey.
Your solution 250774158 for the problem 1941F significantly coincides with solutions harshsharma2024/250774158, TLExceeded/250796278, codingishard8/250800925, Fusu/250810532, 2.16/250811985.
Here is my code : [Accepted] after getting wrong answer with this code : [Wrong answer] and after 3 minutes from getting the wrong answer. I swear that I didn't cheat in the contest, and all the codes in this contest were written by only me and I didn't use any online IDE.
And I didn't like this Plagiarism Mistake at all, not fair facing like these obstacles to get a new rate, specially when I am too close to the new rate.
[MikeMirzayanov] I've compared the solution and I think the similarity between them is normal and many user could do such a solution.
In Round 1941(Div-3), I used Ideone but was not aware that it had public access to my code.My solutions 250660301,250754882 and 250701996 were copied by EducationalCPer and he used them in EducationalCPer/250661584, EducationalCPer/250754701 and EducationalCPer/250701704 and I have received a mail stating that Codeforces would block my account. This leak through ideone was purely unintentional and I would never use Ideone again. Please consider this as this was a grave mistake. Please return my ratings back for this contest.
I am writing to address the violation brought to my attention regarding problem 1931F. I was surprised to learn that my solution (246237500) significantly coincided with several others, leading to a violation of the rules. . As an unwitting participant, I'm deeply concerned about the situation. Unfortunately, I lack evidence to explain the coincidence. I sincerely apologize for any inadvertent involvement in the violation and assure you of my commitment to adhering to the rules in the future. I appreciate your understanding and consideration of my circumstances. Please let me know if there are any further steps I need to take to address this issue.
I was using an extension and by mistake it was synced with a wrong id.. then I manually submitted my code again. That's why two submissions have same code.
Actually I don't know why I have got such message from codeforces. I think there have a mistake.
Sorry ,I sincerely apologize for my mistake i have used ideone.com on default setting as my compiler and i don't know if someone has used my code for my submission . I sincerely apologize for my fault and will not use ideone.com further for compilation and please don;t penalized me for this time will not happen this in future.

I dont know anything about this i have not copied or cheated any code it was my own code
qaq
I mistakenly synced an extension with the wrong ID, leading to duplicate submissions of my code. To rectify, I manually resubmitted. Hence, the identical codes.
sorry, someone took my laptop
Hello, I'm sorry that my English is not very good. I hope you can understand my complaint below. As for the answer to question 1937B, I really did not copy anyone's answer. The system determined that the answer is similar to that of blankKyo, which really makes me speechless. I am a student from China, and I don't know him at all. It is really just a coincidence that the answer to this question is similar. It may be that the way of solving this question is more likely to cause coincidence. I haven't communicated with others through any Internet. I hope you can review our answer and give me a new score
Recently
wherein my solution 252790516 with submission time Mar/22/2024 21:22UTC+5.5 coincides with vibhavpandeystudent's code 252805741 with submission time Mar/22/2024 22:03UTC+5.5.
As someone can make out he seems to use my solutions in his code and upon checking his submissions its clear he indeed copy pasted each and every line with no change(even my handle name at top) to my template making it sure enough for me he copied. I have been giving contests for long and made this template over time.
But I do code on my personal machine's text editor and not any online IDE for sure. I am not sure as to how and why he got my code.
Having been in this awesome community for long I would be helped if this problem be sorted out as soon as possible, it takes time and effort to build a good profile on codeforces for sure and I do not by any means want to harm my personal reputation by indulging in any wrongful way.
Would be helped if this problem is sorted out.

Check this guy's last contest submission. Template is changed in every problem. Has been skipped previously for cheating and still cheated in last contest but was not skipped. @Vladosiya and @Mike please have a look at this.
I dont know how i received notice.i have not even used ideone.I have done my codes on my own.I use python,At a time in a contest there would be thousands of coders,who get same or similar logic for a particular question,they implement that logic.In this approach,due to the indentation and other factors like using the mostly used variables like a,b,c,n,x,y,z,etc..there would be code similarities. Please,could anyone provide me a valid reason...I did not cheated or violated rules.
Received this message:
"Your solution 251771307 for the problem 1944D significantly coincides with solutions rarewelsh/251771307, Sid0309/251788343."
This is due to the use of a common source published before the competition. The common source being https://www.geeksforgeeks.org/palindrome-substring-queries/ (the code towards the bottom). It has been cached more than a year back (and hence before the contest), as can be seen here — https://web.archive.org/web/20230201021116/https://www.geeksforgeeks.org/palindrome-substring-queries/.
I apologize for any misunderstanding, but it was purely coincidental. Please reconsider my ratings.
The issue arose when my friend and I encountered a problem with code solution B. Despite spending 40 minutes trying to debug it, we couldn't get two of the test cases to pass. Eventually, we realized that I had overlooked a case where the sum could be negative. With only three minutes left, we decided to submit our code without making any further changes. I want to assure you that we did not resort to cheating or copying someone else's code. Please restore my ratings accordingly.
Thank you for your attention to this matter.
I want to know what kind of evidence can save my rating
i didn't copy the codes i wrote by own please recheck it again
I didn't plagiarize; these codes are entirely my own creation. Please review them once more.
Please reconsider the rating reduction. Is it possible to have my points restored?
Same here, I used ideone.com so l done this mistake. Next time, I will take care. Please didn't reduce the rating. These ratings are very precious to me
I'm baffled by the notice I received. I haven't utilized Ideone at all. I've independently crafted my codes using C++ 20. During a contest with thousands of coders, it's common for similar logic to arise, leading to resemblances in code structure. Factors like indentation and commonly used variables further contribute to this. I assure you, I haven't cheated or breached any rules. Could someone please provide a valid explanation?
Kindly reconsider reducing my rating. Could you please restore my points?
I see that my submissions are all skipped, I was shocked and then I realised that I wrongly published my solutions on GitHub publically, but I thought I changed it quickly to private so I don't know, can you please give me back my points
Removed
Same Thing
I have received a system mail mentioning plagiarism in the recent (div3) E problem, I think it is because of the template that I have used to get the Divisors of a number which can be commonly found, other than that logic of my code is purely mine and I ensure you that I haven't indulged in any such activities.
I dont know how i received notice.i have not even used ideone instead I used One Compiler.I have done my codes on my own.I use c++,At a time in a contest there would be thousands of coders,who get same or similar logic for a particular question,they implement that logic.In this approach,due to the indentation and other factors like using the mostly used variables like a,b,c,n,x,y,z,count,ans,temp,etc..there would be code similarities. Please,could anyone provide me a valid reason...I did not cheated or violated rules.

First of all I didn't use any online compiler neither I copied my code from anywhere
My submission : My submission
One of the submission that matched : [Some guys's solution (https://codeforces.net/contest/1950/submission/253727515)
Clearly most of the code is just trivial stuff like the factors calculation [GFG Link (https://www.geeksforgeeks.org/find-all-factors-of-a-natural-number/)
Also the guy used 3 loops and i used just two
MikeMirzayanov please look into this ASAP
I am not a cheater and I want that tag removed
Same Thing
The argument regarding number of loops seems genuine.
The other participants have used 3 nested loops, while mercer_2.0 has used 2 nested loops only.
Moreover, already being a Specialist before the contest, there seems to be no benefit of risking plagiarism in an unrated contest by mercer_2.0.
I hope the system will look into this matter as in my case I have also used the code snippet from GFG's blog to generate the divisors other than that I have used my logic which was not that complex to think. For that, I should not be punished.

My CodeTON Round 8 (Div. 1 + Div. 2, Rated, Prizes!) Submission: https://codeforces.net/contest/1942/status
and also I don't even know this guy's
please look into this ASAP
I'm not a dishonest individual, and I request the removal of that label.
Apologies for the confusion. It seems I accidentally logged into my old account as mentioned by the system in email and submitted the solution there.After submit ring, I realized that I should have used my main account. That's why the codes in both accounts were the same. I'll make sure to be more careful next time. Thank you for your understanding.

i don't know him and not published my code any where :/...that's simple problem and may be many user have same solution for B problem in contest:/
my recent contest was skipped due to co incidence of solution d...like there were only 4 if conditions to ensure...that can be same right?
And all of you have unreasonable brackets around (2*(k-1)).
Codes:255358118, 255350377
Doesn't look like a coincidence to me.
While trying to debug my code, I used an online platform Ideone. I think someone copied my code
I have been plagiarized in Codeforces contest Global Round 25. Please check problem C, 'Ticket Hoarding,' on my account with solution ID 255349812. If this has happened, it is merely a pure coincidence, and I kindly request the return of my score.
Thank you

Your code is so obviously obfuscated and obviously the same.
What is code obfuscated sir? But I can see their code is actually different.

Dear Sir MikeMirzayanov,Please review my code once again...I submit it multiple time..Please review again
Hi MikeMirzayanov, Vladosiya
I would like to address the concerns raised regarding the similarity between my solution 255344823 for problem 1951B and others' solutions. Firstly, I want to assure you that I have been participating in competitive programming since 2020 on platforms like CodeChef (ID: aditya0718), Hackerrank(ID: akasaudhan02) and since 2022 on Codeforces. Throughout my journey, I have always upheld the principles of fair play and integrity.I want to emphasize that while the solution idea might appear similar, the code style and implementation details are entirely my own.
Regarding the specific problem in question, I must acknowledge that I initially misunderstood the problem statement and implemented a solution based on that misinterpretation. This earlier attempt led me to explore different approaches, including one where I swapped the k-th element with the first maximum element greater than the k-th element. And then optimal greedy approach eventually led to my solution.
I deeply regret any inconvenience or doubts my submission may have caused. However, I want to emphasize that my intention has always been to solve problems legitimately and to the best of my abilities. I can assure you that I have never engaged in any form of cheating or unethical behavior during competitive programming contests.
Once again, I apologize for any confusion and assure you of my commitment to fair play in all my endeavors.
I understand the concern this situation may have caused, and I want to assure you of my innocence. My code style, thought process, and problem-solving approach are reflective of my own capabilities and experience in competitive programming.
Thank you for your understanding and consideration.
Yep, like everyone here I used ideone without knowing that my code would be accessible to everyone.
Hello MikeMirzayanov MY default settings in ideone.com was public maybe someone copied my code or may be coincidentally our code got matched
Hello MikeMirzayanov MY default settings in ideone.com was public maybe someone copied my code or may be coincidentally our code got matched
why are you a newbie then if you solved last edu round D. colored balls in literally 2 minutes. and that too under an hour of the contest
Man this is too much, just a similarity with one person whom I don't even know..and they're flagging.... Damn what's the probability of this kind of things
Sir,I use python.Most of the times,i used to implement singleletter variables.I dont know why i received mail implying that my codes are being matched with someone else.I used to implement the logic along with proper identation.Coincidentally,it matches with another user(his variables are different,when compared to mine,because I have cross checked the code by entering submission number as i received mail on this regard).This is my second time,that my codes are skipped from the contest NOTE:I dont use any online compiler or interpreter,just run the codes on the local machine.

tbh 256339388 and 256272578 look very similiar. I can't say that it's a coincidence (you literaly have the same empty lines).
As for 1955E, look: 255743237 and 255716716. It looks like you copied function fn and asked chatgpt to rewrite it.

I have been plagiarism in Codeforces Round 940 (Div. 2) and CodeCraft-23[contest:1957] problem C Been plagiarised please check someone can have a pure coincidence as there is no chance for getting penalized for this please check
No way it's a coincidence 257641313, 257640149.
these two again got undetected by just using some variables which are of no use 257640596 257641772 , i already mentioned about this in the contest blog. Vladosiya. They are doing this from past contests too. (https://ibb.co/TTQGHV3)

You're welcome.
don't now how this coincidence occured even i don't use ideone.com . I used to write my code on .vscode
Seems fair 257640392 257630953
please don't skip my answers as it may affact my rating and account as well .
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings backSorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back

Hello Codeforces community,
I want to address the concern raised regarding the similarity between my solution (258442026) for problem 1966B and the solutions by IAmAryanV (258424140) and samarp1001 (258442026). I assure you that this similarity was purely coincidental and not intentional.
I understand the seriousness of rules violations in competitive programming, and I want to clarify that I did not engage in any form of cheating or plagiarism. My solution was the result of my own independent thinking and coding process.
Regarding the overlap with submissions, it's possible that we arrived at similar approaches due to the nature of the problem and there was no as such online study material used. Also i have not used any kind of online platform for running code.
I apologize for any confusion or concern my submission may have caused, and I'm ready to provide any additional information or clarification needed to address this issue.
Thank you for your understanding.

I really don't have any clue about how my submission was similar as the other person mentioned here. For this question I didn't need to pick any code for the solution from anywhere. So I don't have any proof in favor of myself . But I expect that I should not be penalised because of such a coincidence and I just hope that such coincidence never happens with me aga
Sorry, but I can't see the significant difference between 258759470 and 258746270.
Also I’d like to mention that this problem is solvable by a very generic dynamic programming approach and hence it is possible that my approach came up similar to a other’s solutions.I know the seriousness of plagiarism in competitive coding and I assure you that this incident was purely coincidental.I assure you to uphold the values of this community and that is not going to happen again. Thank you in advance.
tf my code doesn't same with other in problem 1969C, pls check it again
Hello very dear Mike, I communicated with my friend about the solution and then we both implement our solutions. We did not share our codes, they're same only because we read the same textbooks, etc. and got same coding styles. As a habit I posted it on ideone.com in public mode and someone must have copied it. Then for some reason I submitted it first in my alt account, and that's why four people have the same code. I was not aware of the rules and really sorry for this. Please give my ratings back

I am not a cheater and I want that tag removed.
I'm afraid all of you used quite specific sintax:
I see that it's not much implementation but the code above...
Just because of that... look at this guy-
online keyboard
he had Skipped before...Plz give my point back Sir.
Vladosiya the ones i mentioned before here with proof(in below links) (and some concluded from failed F cheated submissions which didnt get accepted) only two of them got their sols skipped . Can you check these comments if possible ? https://codeforces.net/blog/entry/129049?#comment-1145804 https://codeforces.net/blog/entry/129049?#comment-1145888
.
Sorry it was a coincidence. Please give the ratings back
Sorry, I received a message stating that my solution is similar to someone else's, but it wasn't a contest, and I haven't cheated. However, I'm not familiar with Ideone as I'm new to Codeforces.

I had written my own solution for this as well as all other questions ,but was unable to submit maybe due to some network error.I was unable to submit any solution.I asked my friend after he submitted his solution to try and submit mine to check if it's working in his device .I sent him my solution for C and it was working on his device * this was after he had already submitted his solution. I then restarted my router and could submit them after .His and my solution are completely different you can check his first submission for the same question below.I request you to consider this as we were not aware of the consequences.We code regularly (you can check our accounts).Below are the solutions ; His solution): https://codeforces.net/contest/1971/submission/260335975 Mine : https://codeforces.net/contest/1971/submission/260382138
Hoping for a positive response. Regards , Sanjeevani Patra
Don't try to trick us please, the mail mentions these submissions: 260382138 260370106
Sir , Respectfully that was the submission after he submitted his ,you can check his account for the submission,i believe their is a submission history present,his initial solution is ; https://codeforces.net/contest/1971/submission/260335975,the solution which the mail mentioned were both mine ,one from his account after he submitted his own solution ,my solution from his account after he submitted his : https://codeforces.net/contest/1971/submission/260370106
MikeMirzayanov @MikeMirzayanov DIV 4 Round 944 Although my code is completely different , but still system detect me as a cheater . let understand each and every problem which i have solved during contest in details.
1.Problem A (MY FIRST SORTING PROBLEM) Question is asking just to find the maximum and minimum element between two element . we are given two integer x, y we just need to find maximum and minimum element . This can be done in O(1). just use max(x, y) gives maximum element and then min(x, y) gives minimum element . i hope you understand .
Problem B (DIFFERENT STRING) Question tells that we have to swap one or more pairs in a string such that after swapping we can generate Another string which is different from the string intial we have . so to solve this we have to take care of following things : is all characters in a string is same then is not possible to generate differnt string. therefore to solve one of the solution which comes into my mind is , just use two pointer and swap elements like while (i <= j) { swap(s1[i], s1[j]); i++; j--; } but this can give wrong answer in case if the giving string is palindrome . therefore better and correct approach would be : start iterating the string from 1st index and check the chracter at ith index is matched with previous (i — 1)th index or not . if it is not macthed then swap then and direct return from there then we can ensure that the string is differnt . but if for the entire string if we unable to find any single pairs which has different adjacent character then in this case we can say that it is not possible to generate differnt String in this case the answer is clearly NO. i hope you understand.
Problem C (CLOCK AND STRING) Question ask that there are two chords in a circle we have you wheather the chords are intersect or not. to solve this we need to iterate over the arc of circle and check wheather the coordinate lie in that arc or not. if both coordinate lie on that arc then answer is NO because they never be intersect similary if both coordinate does not lie on the arc which means that they are lie in different arc therefore and answer is NO. answer is YES only when , one of the coordinate lie in first arc and other lie in differnt arc . i hope you understand.
PROBLEM D (BInary CUT) Question ask minimum no. of cut so that we can sort BInary string . The problem is essentially asking for the minimum number of cuts needed to rearrange the given binary string into a sorted binary string. To solve this problem, we can use dynamic programming. At each position i in the string, we have two choices: Cut the string at position i. Do not cut the string at position i. We need to consider both possibilities and choose the one that leads to the minimum number of cuts. We also need to keep track of whose turn it is, as the players alternate making cuts. We use dynamic programming with memoization to avoid redundant calculations and optimize the solution.
EXAMPLE Input Binary String: 100101
After rearranging the string, we want it to become 000111. To achieve this, we may need to make cuts at positions 2 and 5, resulting in three contiguous substrings: 10, 01, and 01. The first player makes the first cut (10), and the second player makes the second cut (01). So, the minimum number of cuts needed is 2.
Looks very same 260365761 260366342
i can only guaranteed my self , i don't care about what others people do , and i post the question approach as well. if there is any other way so that i can believe you that i solved all these question by my self then please tell me , but i am not doing copy paste . even i can explain problem E and F as well , which i upsolved them after contest .
Hello sir,
I received a mail that my solution was similar to another. I would like the clarify that I solved the problem myself before the mentioned similar solution. Here's the link to my own solution — https://codeforces.net/contest/1971/submission/260335975
The reason for having same solution is that my friend could not submit the solution which she wrote by herself on the platform. She was having some problem so she asked me to submit her solution to check if there was any problem with her solution.
After some time she was able to submit and then she submitted. I am not the writer of the second solution i submitted. She is the writer. But i solved the problem by myself and submitted it as well before the other solution.
Sanjeevani is the writer of the second solution which was same. I did not know that there would be plagiarism check for the second solution as well. Because I was just help her out.
In short I want to tell the before even submitting the same solution I submitted my own solution. Which is — https://codeforces.net/contest/1971/submission/260335975
After this i submitted — 260370106 This solution was written by sanjeevani and she could not submit it on codeforces due to some technical difficulty so she wanted to make sure that this was problem of her personal computer and not the codeforces website, she asked me to submit her solution.
After she restarted her setup she was able to submit — 260382138. And thus it is same as my second submission.
But what i want to say is that I already submitted my own solution
Problem A Question: Given two integers x and y, find the maximum and minimum elements. Approach: Use the max(x, y) function to find the maximum element. Use the min(x, y) function to find the minimum element.
Problem B Question: Given a string, swap one or more pairs of characters to generate a different string. Approach: If all characters in the string are the same, it's impossible to generate a different string. Iterate through the string and check if adjacent characters are different. If found, swap them and return. If no such pair is found, it's impossible to generate a different string.
Problem C Question: Given two chords in a circle, determine if they intersect. Approach: Iterate over the arc of the circle and check if both coordinates lie on the same arc. If so, they never intersect (output NO). If both coordinates do not lie on the same arc, they lie on different arcs (output NO). If one coordinate lies in one arc and the other in a different arc, they intersect (output YES).
Problem D Question: Find the minimum number of cuts needed to rearrange a binary string into a sorted binary string. Appraoch 1 : i came up with this approach after the contest , during the contest i came up with another approach which are also given below. we have 101010 , we just need to consider the pairs of 10 , also cnt the pairs of 01 therefore , answer = cnt(10)+cnt(01)-1 . why -1 , cause after sorting the bianry string we have only one pair of 01 . 00000011111111 , see we have one pair even it is sorted . Approach 2: Use dynamic programming with memoization to find the minimum number of cuts. At each position i Consider two choices: cut the string at position i or do not cut. Choose the option leading to the minimum number of cuts. Keep track of whose turn it is. Optimize the solution to avoid redundant calculations.
Same Issue. Problem 1971E. Solution 260395721. Contest Round 944 (Div. 4). Sorry, Please refrain from deducing my rating.
Hi, By the time I had reached the question (for which I am being held accountable for cheating), I had ran out of time (evident from the timestamp of my submission), which forced me to resort to a very generic boiler-plate template. I suppose the rest of the code was fairly straight-forward and might have accidentally resembled someone else's code. This is the first time that I am being notified of holding resemblance to someone else's code. I have been through a number of contests to reach to the hard-earned rank. Please do not skip my submissions. If having a generic template is a complete no no, then at least do not skip the other submissions in the contest.
[Regarding submission: AnamitraMandal/260424679 for question 1971F]
Hello, I am taken by surprise that I have been flagged for plagiarism for [Sid24J/260422620]. It can be validated that I have always had a pattern in all my submissions which matches this submission as well. It could be a mere coincidence that the piece of code was similar given that the logic and the code piece was not at all elaborate and was very concise. I would request you not to penalise me for it.
Hello admins of codeforce div 4 round 944 contest, I am the owner of im_little and i_love_kheu accounts. 45 hours ago, 2 of my accounts were warned for copying each other's posts and not being ranked. I wonder if you can clarify this issue because those are my 2 accounts. Thank you for helping me. (If necessary, I will show proof that those 2 accounts belong to me, I want both accounts to have high ratings to show off to my friends).
You can write contest from only one account and you can only have 1 account.
Attention!
Your solution 261374026 for the problem 1973C significantly coincides with solutions abc12582200/261369484, kunal0612/261374026. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
Got this message from codeforces , in that contest my rating was somewhere around 1556 so i thought that if i could give today's contest and could not solve C so my rating would get dropped so , in that day i started with problem C thinking like if i could solve this one first i could solve the remaining first and 2nd problem also , so thats why i have started with problem C and hopefully that was mine day so i solved the problem C first and then i solved the remaining two problem ie A and B. I significantly believe that sharing code to anyone is a violation to the contest. I don't know why this happened but okay sorry for it won't be repeated again now i will be coding on my vs code only not in the ideone or any thing. Thank you MikeMirzayanov
Please don't make that contest unrated for me , I haven't copied someones code it takes me 2 years to reach expert and now i am getting the message that the contest get skipped. I will take care of the codes in future with more care . Don't make unrated for me . If i would copy only then i won't be giving 135+ here in this platform right.
@MikeMirzayanov
I have just make of strategy of solving the more harder question first, that why i have started from backwards. I can explain you the whole concept behind that C question. And the second account was mine only i was started with giving the contest with my alt account but then when i get solve the 3rd question preety faster then i thought of giving contest with my main account. I won't be using my alt account for giving contest with two different accounts. If you need any proof i can also share the proof that the both accounts were mine. Please take this into consideration , it won't be repeated again
MikeMirzayanov System
Hello sir you can clearly check the gmail this account is mine only , i just started with giving contest with my alt account and then jumped to my main account kunal0612.
If you want to drop ratings you can drop it from my alt account . But i has been also dropped from the main account itself. I was not aware that this is a violation. Will be not repeating anything like this again in the future. Please do something regarding this.
Same with me,I don't have idea that someone can see my solution on ide during contest, that's why i recieved a msg that your solution is colloide with others. I will take care from next time. I felt something is suspicious because I always code on VS code and there's nothing wrong in that.
What just happened!? If I have to copy other's code then I would have done it ages ago and I would become specialist or expert. and I didn't have idea that someone can see my solution on ide during contest, that's why i received a msg that your solution is coincides with others. I will take care from next time. Also one more thing I always solve code with vscode. So if it matches with others how will I know? Please don't skip me. It took me 22 months to reach here.
Also one more thing that day I was on bad internet service so I couldn't submit the problems faster even though I solved it before submitting. I am sorry if it matches I will just solve with my vscode not with any online ide. Please just don't unrated me.
Please give my ratings back.
I as well used ideone and not aware of this rules as I am new to this contests giving on codeforces. I am sorry for the mishap due to my lack of knowledge and I sincerely convey that the code was written by me and not copied from any source. Please don't penalize me or block the account. Thank you. I will not use any online ide from next time. I humbly request you to not penalize for a mistake that I didn't commit.
I used Ideone on default settings as well and wasn't aware about the rules, I kindly request you to not block me or give me any penalties as i'm new to this platform. I apologize for my mistake. I won't repeat this mistake again and will take care of my solutions that they won't get copied. Please just don't unrate me,i'll always code in VS Code from now on and not on any open IDE like Ideone. Thanking @MikeMirzayanov for this.
I didn't even use any online compiler. I simply use VS code. I didn't know what happen but it seems that the process of the solution of mine may coincide with other. I don't know how it is even possible. But the idea was original for myself. Now tell me what to do if I want to avoid this type of situation. HELP ME.
Recently in the concluded round of Codeforces round 945 div.2,I got a message saying Attention!
Your solution 261400751 for the problem 1973B significantly coincides with solutions.... .However I did not copy my code from anywhere . I thought about the solution for a long time into the round and neither did i use ideone.com for compilation or anything. I wrote the code all in mt visual studio code . I even have the proof of it. I learnt my solution algorithm which is a sparse table bitwise OR from https://www.geeksforgeeks.org/sparse-table/ .This resource already has been provided on the internet long before the contest, hence i urge MikeMirzayanov to kindly look into it and not let my rating go down.This is my submission https://codeforces.net/contest/1973/problem/B
I too used Ideone as well and wasn't aware about the rules, I request you to not block me or give me any penalties. I apologize for my mistake.
moreover i thought of the logic....taking some time in even thinking.... i urge MikeMirzayanov to not let my rating go down.
As we All're coders so it's definitely sometimes ..I become coincidence. It's not possible to share codes anywhere
I don’t know why I received an email regarding this. All I did, was write the code on VS code, then use tester on vs code to test the sample input output and then copy paste the same from my local folder to submission window. I can even show my code file if required. Please resolve this issue.
Sorry but it was an Coincidence....
Hey, MikeMirzayanov I received this email today: Attention!
Your solution 261897698 for the problem 1974D significantly coincides
I attempted my first ever contest[contest:946] while transitioning from python to cpp, and I have no idea about why this occurred, one thing that I know is that I have not copied it from anywhere, I might have taken reference from a similar python code, but definitely not copied from anywhere and I used an online complier https://www.onlinegdb.com/ which I am not sure if it will cause an issue or not.
I hereby request you to not block my account or takeaway my rating!
Do not skip my previous contest it will never happen again.
Hi MikeMirzayanov
I just received a message saying that my solution in the last div.3 contest coincided with someone else's.
Attention!
Your solution 261889219 for the problem 1974C significantly coincides with solutions Meem-Seen/261889219, Ankit_Yadav_215/261900812, blue_chair/261904481. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

I swear that I didn't cheat in the contest, and all the codes in this contest are 100% written by me. I didn't use an online IDE. I don't know the other two users. A trivial approach to the problem causes I believe many other contestants to use the exact same method too. I hope I can get my ratings back
I don't have idea that someone can see my solution on id during the contest time, that's why I received a message that your solution is colloid with others. My solution was developed independently, and any overlap was purely coincidental. I did not intentionally share my code or collaborate with others during the contest. I don't cheat, I will be careful next time.
Sorry i also used ideone with public access and ensure nothing of this sort will happen again.. please give my ratings back
i have participated in cf round 945 div2 and i have solved a on my own . and i had idea of b and refered to bit manipulation material i have reffered to sparse table article on gfg it is published before the contest itself. and solved c on my own. but it is showing plag for b and skipped the entire contest. what to do now.
.
I used Ideone will never do this from next time.i did not knew it was default by public
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back
I have received a message , i have not copied solution for anywhere nor took help from someone and i did not publish my code in any public forum , the code i have submitted is completely written by me , this is purely coincident as the implementation of the solution is pretty straight forward please.
My ideone was on default settings. That's why this issue occured. I've fixed my settings. Do I have to do anything else?
No you don't
Still they didn't return my points.
I got a message saying it matched with some other people. My code is solely written by me and not shared with anyone else during the contest or before the contest. I wrote the code on my own and i am aware of each and every logic implemented. I truly dont know how it got plagged like this. I request you to look into it. If i were to explain the code, I can perfectly do that. Please help me regarding this. i will try not using any online compilers which might have caused to have the same syntax, but I didnt copy any code that is made available online. Please help
I received this message stating: "Attention!
Your solution 262757700 for the problem 1977B significantly coincides" Please check my code again. It's different from many others. Be it the variables or functions or any other thing I used. I dont know even a single person's account from that list. How come a person be blamed simply for a mistake which he didn't commit. Both the questions i submitted were skipped and not evaluated. I sat for two hours in the contest and simply you can't do like this to my rating. Kindly look into this and help me by rectifying and not punishing for mistake which i didn't commit.
This is totally unfair from codeforces. Still unable to figure out why my submissions were considered as copied or cheated . Please don't give us a bad impression on this good website. The questions I solved were really a basic ones and didn't involve any complexity. Being a beginner i could solve either one or two questions that's all. It's not fair enough to skip the evaluation of both my answers that way.
Hi MikeMirzayanov
Today I got this message regarding solution conflict in 1977C but to my surprise only our templates are same whereas the rest of the main code and logic are completely different. Can you check into it asap please?

MikeMirzayanov
I got cheated tag today because of a misconception that I copied the code from someone, and my code is matching someone else code.
so first of all, yesterday for the first time in my competitive journey I used ideone.com and this was because my VsCode IDE was not working due to some launch.json file error that is why i tried to write code in ideone.com even i dont know how to use this website but then after some time i understood their platorm and started writing code over their but i really dont know why my code got leaked i visited that website for the first time and got this cheated tag i dont know how my code got leaked and got copied by others
in my past contests i never ever got this tag for cheating because i did that codes in my personal vs code and i dont know why this time i got this tag , i think this is because of ideone.com website
in short due to usage of ideone.com for the first time because of some launch.json error in my vs code my code got leaked publicly .
now please understand my situation and take fair decision as i not cheated at all , also you can check my perfomance in previous contests which may give my honesty proof.
hope you understood !
Codeforces Round 947 (Div. 1 + Div. 2) and Codeforces Round 948 (Div. 2) i solved total 3 problems in this 2 contest, but not seeing them in my contest history. I got an email today i understood what happen.
I am extremely sorry, i am new to codeforces and i had no idea that my solution could get steal if i do them on online complier( i do them in ideone, because most of the guy on youtube use ideone in their tutorial ). from now and on i will not use any online complier.
I am genuinely sorry if i violated and rules of codeforces.
Respected sir, It's a humble request sir please review my code and check from which person it will be coincide exactly , i revied other people submission which are mention in message , but i did not find anyone which has same code as me . my code and other people code is different in term of code quality , On what basis system targeting me as a cheater . Sir it's a humble request please check carefully . Suppose there is a question to find maximum element between x,y ? then everyone will coded as max(x,y) then are they cheated ? No , Similary Logic is same for most codes but the way of writting code and code Quality is Completely Different . sir i can write editorial as well but before it please review my submission again .
@MikeMirzayanov
@Vladosiya Sir please review my submission . it's a humble request just review it.
I hope this message finds you well. I am writing to address the accusations regarding the solutions provided. While I understand that similarities may exist due to the nature of the mathematical concepts involved, I assure you that any resemblance is purely coincidental.
Firstly, I must clarify that I am not acquainted with any online platforms like ideone(which i came to know about today itself), thus any insinuation of copying from any website is unfounded. Moreover, I refrain from using online compilers. I strictly use vscode, unless and until there is a strikingly understandable bug ,i use devc++.
I had few approaches one using direct conversion from decimal to binary and reversing that i could not implement for 0th index array(which i later tried but failed). Another approach being the usage of two vectors v1 and v2 for storing pos and neg (1 , -1) but while that did fail(due to reoccurence of same element) , a single vector was fine enough for the purpose with the mathematical logic that i came to be with and that is exactly what i implemented.
If you review my solution you could see that i have used v2 simply because i had to clear my previous approach of using two vectors(and that is why my submission was significantly late than others mentioned in the (talks)).
I genuinely value academic integrity and adhere strictly to the rules and regulations set forth. Therefore, I kindly request that the accusations be retracted. Should the evidence fail to convincingly support the allegations, I trust that appropriate action, as per the regulations, will be taken.
I appreciate your attention to this matter and remain hopeful for a fair resolution that upholds the principles of fairness and justice.
Thank you for your understanding and consideration.
I want to clarify that I did not share my code with anyone, nor did I copy from others during Codeforces Round 948 (Div. 2). I submitted my solution for the second question in under 11 minutes, and although another participant also submitted a similar solution, I assure you I have always upheld the principles of integrity and fairness in competitive programming. Increasing one's rating is challenging, and I would never compromise my standing by engaging in unfair practices. I am confident there is no misconduct on my part and request a thorough review of my submissions and activities during the contest. Thank you for understanding, and I hope this matter can be resolved fairly.
Yesterday,I got mail, Attention! Your solution 262753837 for the problem 1977B significantly coincides with others solutions . I want to clarify that I didn't cheat and shared my code with other participants.I go through to others solutions they were have same logic as of mine.I worked hard to improve my rating since 5 contest regularly participating in them ,and I finally became pupil in Codeforces Round 947 (Div. 1 + Div. 2) but then this accusation of cheating decrease my rating to 1091 (-132) this is very disheartening . Go through to my previous contest and their solutions .I never got this accusation except when I submitted similar solution to my other handle endless__123 . Kindly revert back my old Rating . Please respond MikeMirzayanov
I participated in Codeforces Round 948(Div 2) and my solution of B has been skipped.
I want to draw ur attention to the fact that more than 20 LGM.s and GM.s have exact same solution.
I am putting out the list of it. tourist:262719839 jiangly:262770013 Sugar_fan:262726603 maspy:262721500 dreamoon_love_AA:262727169 Alpha_Q:262735278 ....:262741836
my submission :262750926
these are the submissions I found on first page and there are many more.
Therefore I ask Vladosiya to please look into it.
Vladosiya and MikeMirzayanov please reply regarding this
Even though the logic of B is pretty simple, the specific realization in your code was leaked for sure.
Also I took a look at your other submissions and C solution looks a bit close to one of leaks (for example your solution 262776958 and a leak 262775032, not completely same but makes your case less arguable to be honest).
I submitted 4 times the solution for C but all were wrong on different pretests. I did not get AC on C even after 4 incorrect submissions. I only did A and B during contest. If I would have cheated I would have surely done C too to get a better rank I hope you reconsider my request. Vladosiya
I would like to clarify that the solution I submitted for problem 1975A was independently developed by me. The problem itself is quite straightforward, involving checking if an array can be sorted by rotation. This type of problem naturally leads to a common algorithmic approach, which is likely why my solution resembles those of other participants. Specifically, it involves sorting the array and then checking each possible rotation to see if it matches the sorted array, a well-known method for this kind of task.
I assure you that my intention was not to violate any rules, and I did not use any public code or resources such as ideone.com with default settings. In future competitions, I will take extra care to personalize my solutions to avoid any appearance of impropriety. please don't penalize me for this.

Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
Surely I did not copy it, and for the record, I often use online compilers like programiz/ideone as a habit, which I shouldn't have, but I am not sure why my solutions are skipped. Would you please have a look and verify and maybe give my rating back?
Thank you
Sorry but it was a coincidence. I published my code on ideone.com may be the answer leaked.
i undersatnd what happend in the latest codeforces div 3 , as you mentioned that my code can get steal if i do them in ideone but i do code https://www.onlinegdb.com/online_java_compiler in this platform and always save my code. i never knew that my code could get steal.
now i think i will start coding in sublime or codeblocks(i don't do code on codeblocks cuz it has no dark mode and i hate white screen and as a beginner i am having hard time to setup sublime). but no problem from now on i will do code in codeblocks/sublime
Sorry for this, i used other tools and my code is copied by someone, I will again not do the same mistake
I am reaching out to address the recent notice regarding the similarities found between my solution 263326766 for [problem:1976C]and several other submissions. I want to take this opportunity to formally state my position and vehemently deny any violation of the competition rules.
I assure you that I approached the problem with the utmost honesty and integrity, strictly following the guidelines set forth by the competition organizers. My solution was crafted through my own diligent effort and was not influenced by any external sources or collaborations.
However, I must express my sincere apologies for any inadvertent similarities found. Upon reflection, I realize that I may have inadvertently used tools or resources that inadvertently led to similarities in the code. I take full responsibility for this oversight and assure you that it was not my intention to violate any rules.
Rest assured, I have learned from this experience and will take extra precautions in the future to ensure that such mistakes are not repeated.
I kindly request a comprehensive review of my submission, confident that upon scrutiny, it will become evident that there has been no intentional breach on my part. I stand ready to provide any further information or clarification necessary to resolve this matter promptly.
Thank you for your understanding and attention to this pressing issue.
Dear Codeforces Team, I would like to address the similarity between my solution (ID: 263344459) and the solution submitted by another participant for problem 1976B. Both of us have practiced competitive programming together, which might explain some similarities in our coding styles and approaches. However, I assure you that each solution was developed independently during the contest, and no specific solutions were shared or discussed during the contest.
Here are some key differences between our solutions: 1. Data Structures: My code uses arrays, while the other code uses vectors. 2. Calculation Logic: The logic for computing the final result differs, with different approaches to updating variables and checking conditions. 3. Variable Names and Types: The variable names and types differ significantly, indicating independent coding styles.
The similarities in our solutions are coincidental and due to the common nature of the problem and typical approaches in competitive programming. I understand the importance of maintaining the integrity of the competition and kindly request that you consider these points when reviewing our solutions.
Thank you for your understanding and assistance.
I got a warning from Codeforces about my solution being similar to other participants. This is to tell I had been using ideone for running my codes and wasnt aware of its public private feature. Moreover that was the only bruteforce solution I can think of. I was literally a fool for using it just to save time, I promise I wont repeat such a mistake.
I have been sent a notice regarding integrity issues for the problem 1976C for my submission 263358996. I would like to take a stance to deny any dishonest practices or use of methods that violate the organisation's rules.
I have attempted the question with my utmost honesty without any external help or collaborative work. I do understand there have been similarities and believe it might be possible because of use of similar tools or resources.
I am quite new to platform and will take this unintentional mistake as a lesson and promise to be take more precautions for further contests.
I am willing to provide further information during the review of my submission. I hope my plea is taken into consideration
I believe I accidentally used Ideone in public mode without realizing that others could view my solution. Consequently, someone copied my work. I'll take care of that in future.
？
hello codeforces i got a mail about my solution matching with others div 3 950 D solution. with complete honesty i would like to say i was solving problem first i thought to just take difference array and find the index where decreasing order is hindered and try to change that particular instance than after locally running it result was wrong than i thought to not only change problem creating index but also the previous one. abc — first i thought to change only b than a too de (d>e) after that i realized that i should consider all three cases till then 20+ minutes were passed so i did a fullish thing which i regret now. i won't do it ever again but i was capable of solving it. i request u to please leave me this time as i was capable of solving it. rest i understand it. Thanky
i already wrote comment for recent div 3 but still got another mail why ??
i explain my situation for the same div 3 in my previous comment
I have not cheated for question Round 950 question C. I have been using the same boiler plate code from more than 6 months and you can check all my previous submissions also. They all have same boiler plate code.
I used Ideone and wasn't aware about the rules, I request you to not block me or not give me any penalties and don't lower my ratings, I apologize for my mistake. [user:sachin07sgsingh][contest:Codeforces Round 950 (Div. 3)]
IAM receiving a message from system that solution of problem is same with others but I was using clion idle but unfortunately the my code was same with others please I want know what will be with me ?

I did this code on my own i took little help from chatgpt but changed the code as it was not givving me correct output please don'y reduce my ratings other time i will write the code from scratch on my own and avoid use of third part source.
I have used ideone in public mode by mistake because i don't have any idea that someone could see my solution there. That's why my solution has been copied by somebody. I am really apologize for that i would not made a mistake again.Please give my ratings back.
Its better to code in online c++ compiler other than ideone bcoz it doesnt makes code public. ideone.net however being more user friendly but it has privacy issues when not taken seriously.

Your solution 264017343 for the problem 1980C significantly coincides with solutions tourest23/264005833, vatskushagra1105/264017343.
I got this email from codeforces team and I just want to say that the approach i used was very straight forward there can be a possibility that someone else also used that approach but I wrote the code honestly and clearly in java and never copied it. I request you to please rectify it.
I got the same for last contest also

Hi mike I want to draw your attention to this issue that today I got this message from system that my code is significantly similar to joooooo222 in d question. I am a Mac user and I can't compile gcd function in my computer so I used ideone to compile my code. I didn't know that code can get copied from there too. But you can look at the account of this guy joooooo222 he has all his question plagged and even he submitted multiple solution to same questions during the contest I don't know why he wants someone else's code to be flagged but my code was written by myself. Please remove that plag from my account as it destroys my hard work due to some one else's cheating.
Why am I getting downvotes and no support.The downvotes can check my id and joooooo222 id.
[Deleted]
yo, joooooo222 also copied my code and I got a warning
(nevermind, I need to check it carefully)
Thank you, MikeMirzayanov and the experienced members of the community, for clarifying the rules around third-party code usage. These updates strike a great balance between allowing pre-written code and ensuring fairness and originality in competitions. The emphasis on respecting licenses and copyrights is also crucial. Looking forward to the upcoming contests with these well-defined guidelines. Great job!
Codeforces Round 950 (Div. 3) i solved total 3 problems in this contest, but got an email for the problem 1980C. I understood what happen.
I am sorry, I didn't knew that my solution could get steal if i do them on online complier. I use online compiler often, because one of my friends told me to use that. As i got the problem, from now and on i will not use any online complier in public setting.
I hope you will understand my situation & consider.
Do you really think that anyone will believe you, dirty cheater?
I've been skiped for the last round the story is that me and my friend who have been training together as a team for 6 monthes and we have build a huge reference and such a problem "D" have one and only soulution which is so obviece and many of the soulution was copied from the sharing reference we have together
hi
Hello, in codeforces round 950 I submitted the same code from my second account which is CodeWeave, as the code is written by me and both the accounts belong to me, it is not copied or cheated, I can give enough proof that the account CodeWeave belongs to me. If it's still an issue I promise not to do this in the future. Can I have my rating back?
MikeMirzayanov or Vladosiya, can anyone reply please.
using two accounts for the same contest is considered cheating.
Hi MikeMirzayanov and System,
Today I got the mail- Attention!
Your solution 264413187 for the problem 1979A significantly coincides with solutions chumlee123/264413187, Ayoowhaa/264413870. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details.

In case of repeated violations, your account may be blocked.
But the solutoion to that problem was pretty trivial we only had to find the lcm of the entire array and then divide and sum each element by the lcm and if that sum>=lcm we had to print -1. Now the sum part and boolean logic was pretty trivial and the way to find lcm could be found online like LCM of array1 and LCM of array2 which is similar to my calculation of lcm.
Please look into the matter and revert back my ratings.
I got mail that my solution for problem D and E in round matched with some other solutions codeforces round 950 div 3 .I have those solutions written in my vs code
I don't understand why my rating was not updated..before submitting the question i have used ideone to check my code.I don't know that it is in public mode..I will make sure that this will never happen .Could you please give my rating back..
Same, I had tested my code on online compiler-ideone.com in round 954, which led to the issue. I sincerely apologize for this mistake; it was not my intention.
for Educational Codeforces Round 166 (Rated for Div. 2) 3 days ago I received a message — Attention! Your solution 263359684 for the problem 1976D significantly coincides with solutions VorteX03/263355507, logiccrusher/263359684. Such a coincidence is a clear rules violation.
considering the second statement in above blog:- 2. the code is generated using tools that were written and published/distributed before the start of the round.
I would like to say that I have used tools like chatgpt(https://chatgpt.com/c/83f57492-5895-4c84-a614-660f1244953f) and copilot AI for some help in writing code and as these tools were published before this round I would like my penalty to be revoked, I used it to convert languages of my codes also.
solution of 1984B was matched by others as i new in codeforces i use ideone first time and my solution was leaked from the next time it didn't happen please give me my rating back logic of others are same but code are diffrent please give my rating back
I would like to inform that during the contest(Codeforces global round 26) my submission of the problem 1984B with other users coincidentally ,I don't know how it was happened,I think I forgot to change the default setting on ideone due to which many users copied my code and submitted it .please codeforces take a look into it and please give back my rating,because I got -51 for nothing.please take a look and i will never do this mistake again. My submission:
include
include<bits/stdc++.h>
define ll long long int
include
using namespace std;
// Function to check if a given string is valid void checkString() { string input; cin >> input; bool flag = true;
// Check if the first character is '1' if (input[0] != '1') { flag = false; // If not, the string is not valid } else { // Iterate over the characters of the string starting from index 1 for (ll index = 1; index < input.size(); ++index) { if (index != input.size() - 1) { // For characters in the middle of the string (excluding the last character) // Check if the character is '0' if (input[index] == '0') { flag= false; // If '0' is found, the string is not valid break; } } else { // For the last character of the string // Check if it is greater than '8' if (input[index] > '8') { flag = false; // If greater than '8', the string is not valid break; } } } } // Output the result based on the validity of the string if (flag) { cout << "YES" << endl; } else { cout << "NO" << endl; }}
int main() { int testCases; cin >> testCases; while (testCases--) { checkString(); // Process each test case } return 0; }
i am sure my solution didn't matches with others, bcuz i do them in codeblocks this time
Hey, I wanted to inform that my email id was logged in to one other device. I was using codechef ide, where anyone with that email id can login get the last code executed at that ide. That is what happened with me in question 1984C2. My submission id is 264957292. You can verify it. Please consider my request, I will make sure to avoid these mistakes in future.
I think this comment already exists.. but it is what I am writing
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody. I make sure that I'll take care of this in further rounds.
I read the comments down for the first time and I got to know that how dangerous it could be to use ideone.
The same happened with me as well I was writing my code using ideone.com in public mode didn't know this would happen. I am sorry for what happened in this contest. Now onwards going to use sublime!
There is also a possibility that someone leaked my code from the hacking room.
Moreover, This was my 27 th contest and I have a very clean record. I have also practiced several problems on Codeforces. Such things clearly show that I am not a cheater.
I would request MikeMirzayanov to look into this matter and revert my ratings and solutions back as clearly there is no fault of mine in all this(knowingly).
I sincerely apologize for whatever transpired and adhere to the consequences for future. I also take responsibility for such concerns happening in future.
This time please take into account that similarity in my code was not because of cheating, but unknowingly I might have voilated codeforces policy which will definitely be taken of in future rounds.
Moreover the people mentioned in the mail I received are totally unknown to me. I have heard them for the first time. So I hope u will understand my concern.
I made the same mistake
I have not done any code copying like thing....all of logic and code of question F belongs to me only. Please don't skip my contest.
.
It was my first contest and do not have any idea about my code to be copied from ideone.com.It never happened to me and I was completely unaware that this can happen to me.I promise to take care of my code during the contest and will never use the ideone.com for code.
You can check my id I have never given contest so I have no idea of cheaters.I am at Guardian level at leetcode so can't do such unprofessional things.
I will take care in future I promise.Please do not do anything with mny ratings and other actions.
@MikeMirzayanov Your solution 266031191 for the problem 1978C significantly coincides with solutions ritwikdurga/266031191, soubhagyabhowmik001/266031538.
You just gave yourself away, stupid cheater
Sorry if it hurt you anyway but my previous accounts names were not formal so that i cannot keep them in the resume. Hope this helps you get some clarity. Thank you.
fuck you, you just changed the comment here is the original text:
"@MikeMirzayanov Your solution 266031191 for the problem 1978C significantly coincides with solutions ritwikdurga/266031191, soubhagyabhowmik001/266031538.
I think the solution is only coinciding with one person.I wrote this code on my own even the logic and the code format that i have submitted. I didn't use any kind of online editor or anything. I just wrote the code on my own. And more over This is purely coincidence as no way a copied code be same for just one person. Please help me with this. This time its crucial for me as i have to submit my details for a job interview."
What do you mean. I changed it just because i don't want to beg other for my rating to stay just because i have an interview. That's what is called as self respect which people like you doesn't have. Just keep going for the rat race and get placed in some shit company having no life and do the 9-5 you mf. Thats your place and you will get it for sure. You sucker. Just go to hell already! Thank you.
You are stupid cheater, you even cheated in your last competition. When your skill is not enough to solve a problem, you cheat and translate the decommissioned code into python, I have no doubt, using ChatGPT. And you still call me a sucker? You will be thrown out of your place of work as soon as they find out that you really are a stupid loser.
Nah nah nah. Keep going keep going. Karma will hit you back with each and every word. I will remember you for life.
I am writing to appeal the decision regarding the similarity between my submission and that of another users in the recent contest. I would like to clarify that the code I submitted was entirely written by me, and the logic used to solve the problem was developed independently.
While I understand that coincidences can occur, leading to similar logical approaches, I can assure you that my implementation is my own work. Here are a few points to support my case:
I have been diligently working on improving my coding skills and solving problems on my own. I take academic honesty very seriously and ensure that all my submissions are a result of my own effort.
Although the logic might appear similar due to the nature of the problem, the actual code implementation differs in structure and style. I can provide further details on my thought process and the steps I followed to reach the solution if required.
The problem at hand might have a common logical approach that many contestants could arrive at independently. Given the constraints and requirements of competitive programming problems, it is possible for multiple users to think along similar lines.
I sincerely apologize for whatever transpired and adhere to the consequences for future contests. I also take full responsibility for ensuring that such concerns do not arise in future rounds. This time, please take into account that the similarity in my code was not because of cheating, but unknowingly I might have violated Codeforces policy, which will definitely be taken care of in future contests.
Moreover, the people mentioned in the mail I received are totally unknown to me. I have heard of them for the first time. I hope you will understand my concern and consider this in your review.
I kindly request to not to skip my contest and rating.
Thank you for your understanding and consideration.

hey MIKE !! I have no idea how this guy has written exactly same code as of me . my submission 266037920 . I think it's a coinsidence I used online gdb for code compilation . but after looking his profile . I got to know his all answers were copied and skipped
Image Link :https://ibb.co/TKs9k1d
I'm so sorry for using online compiler .. this mistake won't happen from again. I'll comply with code forces rule and regulations . Thank you.
I had no idea that someone can see my solution on ideon during contest.I'll be using a private IDE from next time onwards.I will take care from next time.
Please give back my ratings.
Happened by coincidence but this rating is important to me
.
Hi Codeforces, I participated in Division 2 Contest 953 yesterday and got an email today telling me that my solution to question 3 is similar to some other submissions. I honestly write this to say that neither I have seen or copied the code from any online source nor do I write my codes on any online platform, hence no chance of leakage from my side as well. However, upon some close inspection, I find that even the editorial for that question has used almost the same logic and similar code, and it was definitely not hard to think about if given enough time. My submission:(https://codeforces.net/contest/1978/submission/266037354). I therefore believe the cause of the similarities in the submissions of other participants is because the logic was just not very tough to think about, and once it is thought out, the similarities in the coding part are no surprise. You can also see that my template for all other submissions is the same as this one. I do not know any other means by which I can prove my innocence, but if the team does want any details, I am happy to provide them. I therefore request that the team look into this matter and please consider my request to not drop my ratings and skip my submissions.
I have Tried Running My code in ideone.com in default settings i don't know about default settings, i have changed my compiler & not going to use ideone.com again, can you please look into the matter that has occured for the problem 1987D.
also i have used ideone.com for all of my problems done in yesterday contest, so there ain't any match with all 3 but a match with D one only i didn't get this.I will make sure not to use ideone.com again but don't skip that questions as it takes a lot of time to do them.
nice thing to detect cheaters.
Sorry but it was a coincidence. I tried my code on ideone.com unkonwingly, that's why the problem has occured.I am really sorry but I didn't meant to do that.
Hello Codeforces, Sorry but it was a coincidence. My solutions for the Codeforces Round 954 (Div. 3) was tried on ideone.com, that's why the problem has occured. I am really sorry but I didn't meant to do that. I also believe the cause of the similarities in the submissions of other participants is because the logic was just not very tough to think about. Please give the rating back for my contest. I have not violated any rules of the Codeforces or the contest. I will not use ideone.com again. I am really sorry. I don't even know who are the people from which my code is same. I do not know any other means by which I can prove my innocence, but if the team does want any details, I am happy to provide them. I therefore request that the team look into this matter and please consider my request to not drop my ratings and skip my submissions and give back my rating for the contest. Please it's a request don't skip my submissions. I have worked very hard in completing the contests. The contests are very important for me. Please don’t ban my account and skip my submissions. Please its a request. This mistake will not be repeated ever again I promise. Please do the needful as soon as possible as the contest rating are very important for me.

hello codeforces, a crocodile this side. i have been consistently solving difficult problems and watching topic streams of every famous competitive coder because I find this really interesting. note that i started coding around 4 to 5 years ago and you can see that in my graphs. after that, i had jee prep due to which i went afk but kept practicing and recently started again. i gave 3 contests after coming back, solving a b c1 in a global round, then I gave a dov 2 but some unavoidable issue came up at home due to which i could only solve a and b. then there was a div 3, at which I was completely focused and solved a to d on my own. afte that, my brother said he had solved e and f because he was giving the contest in another room, and started explaining the solution to me. i did not use any drive links or anything of that sort to copy from, and this coincidence is a result of carelessness on my part in terms of listening to him, and i assure you this won't happen in the future. i am alright with any rating change penalties codeforces night deem fit for this violation, but urge them to kindly not ban my account. thank you so much.

Subject: Clarification and Apology for Code Similarity Issue in Problem 1986F
Dear MikeMirzayanov,
I hope this message finds you well. I am writing to address the issue concerning the similarity of my solution 267059493 for problem 1986F with solutions RLVxx002/267057701 and wandasd/267059493.
On June 23rd, I participated in contest Codeforces Round 954 (Div. 3). This was my first opportunity to achieve such a high level in a contest. I had a good understanding of the solution for problem F and had completed most of the code. However, I forgot to reset the array during each solve attempt, an oversight I did not realize at the time. In my frustration and eagerness to get the problem right, I posted my code on https://www.luogu.com.cn/paste/jk7lrzuu, seeking help to debug it.
I now realize this was a mistake, and I should not have shared my code publicly. I did not anticipate that someone would take my code, modify it, and submit it as their own. I deeply regret this action and understand that unintentional leakage is still a violation of the rules.
I am sincerely sorry for my actions and the resulting issues. I kindly request the reconsideration of the decision to suspend my account, as this is very important to me. I assure you that I have learned from this experience and will adhere strictly to the rules in the future.
Thank you for your understanding and consideration.
Sincerely, wandasd
Sorry.
Sorry
Dear @MikeMirzayanov,
I saw that only my solution (ID: 267069280) for problem 1986F got flagged for similarity with other submissions. I want to let you know that my solution is my own work. I didn't copy or share my code with anyone.
I can provide screenshots showing the IDE I used for that submission. I only use offline IDEs and not any online ones. I also don't know any of the other users whose solutions are similar to mine. As I reviewed, their submissions are not quite the same to me.
Thank you for your understanding and consideration. I hope this matter can be resolved promptly.
Best regards, harshie_
Sorry
Sorry
I deeply apologize for this inconvenience, but I really thought that my logic was different but due to some miss happenings it happened. It was really a coincidence. It will never happen again and I will make sure that my code and logic is unique. I sincerely assure you that this will never happen again in future. So Sorry.
Sorry
hrry
Sorry
Sorry
Truthfully Speaking, I haven't cheated in the Contest. That day my VS Code Run button disappeared, so I coded the solutions on Online C++ compiler and have done the questions by myself. I haven't cheated in the contest and want my ratings and question back.

You can't appeal to standardness if you copy a ton of unnecessary details: 267074043 267057600
Sorry, but its just a coincidence as question was easy so codes may match a bit .from next time and other contest i will try to take different inputs as much as i can.
I generally run my code on ideone and some one copied from there and i am new to that and i donot know that anyone can copy it so it happened unknowingly.
Dear Codeforces team I am new to the Codeforces platform. I recently participated in the contest where my solution was flagged for similarity with other solutions.I am truly sorry for this incident. I had no intention of violating the rules. I have learned from this experience. I will be careful. I kindly request your consideration and understanding in this matter.
Sorry for this, I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody.
Subject: Clarification and Apology for Code Similarity Issue in Problem 1986C
Dear MikeMirzayanov,
I hope this message finds you well. I am writing to address the issue concerning the similarity of my solution 266995241 for problem 1986C with solutions lover_boy/267012690.
The solution for problem 1986C was completely within my capability, and I completed it quickly. I was also surprised to see that lover_boy's code was very similar to mine. Perhaps our approaches were identical due to the limited flexibility in solving this particular problem. I assure you that my solution was independently developed. For a contest with 40,000 participants, this is purely a coincidence.
I kindly request that you reconsider and unban my account. Thank you very much for your understanding and assistance!
Sincerely, wandasd
Dear MikeMirzayanov,
As wandasd already stated, the sole reason for the similarity in our code is the limited flexibility and simplicity of the question.
I don't know how to prove our innocence in such cases where the code matches. You can match with my performance graph that I performed as per my rating
Hello,
I want to convey my message about last contest problem 1986D, that I have done it on my own and even do not know who jayant24sha actually is. So Please take my message seriously
I don't know why I judged my source code to be similar to someone else's, I don't know why, it all counts as a mistake for me, and if my account is banned because of this, I really don't know why, how to prove myself
I submitted the code way before all the submission for we can clearly see that. So i hope that MikeMirzayanov will help me out in this situation.
Please do not mark any penalty or block my account.. I am unaware about it.
Hey Codeforces!
3 days ago I participated in Codeforces Round 954 (Div. 3). Today I noticed my solutions are all skipped.
I also checked my mail and found that I have been plagued.

Thanks!
I'm sure you're kidding, it's just one big obfuscation and you know it 267062179. definitely the same as the leaked code.
Dear Codeforces Team,
I received a notice regarding my solution for problem 1986C coinciding with another solution. I want to provide some context and clarify that there was no intention of violating the rules.
I don't know or have any relation with the user phenomenal_ajax.
The code written by me was my own source code with my own logic, kindly understand my concern. It was a simple understanding of identifying unique indices to be replaced by smallest chars in the string to make it lexicographically smallest by sorting the unique indices in ascending order for that I used data structures like set and vectors, similarities found are purely coincidental.
I have always aimed to follow the competition's rules and guidelines. I appreciate your understanding and am willing to provide any further information if required.
Thank you for your attention to this matter.
Best regards, [user:invincible_0206]
Dear Codeforces team, I am new to the Codeforces platform. I recently participated in the contest where my solution was flagged for similarity with other solutions.I am truly sorry for this incident. I had no intention of violating the rules. I have learned from this experience. I will be careful. I kindly request your consideration and understanding in this matter.
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody
I have received a notification regarding a significant similarity between my solution for problem 1982C (submission ID 267390579) and those of other user (cypher00/267363362 and shaurya21200/267390579). I would like to clarify that I clearly wrote the solution myself independently . I have not used any other platforms and don't really have any evidence for that but you may check the timings of the submission and testcases , I clearly came up with the solution which I wrote on vscode . But I have no issues in providing any explaination if needed as the rating is really important for me as it took a lot of time to come up with the working solution . Please reconsider your decision as I clearly have no idea who the person is and I have done my solution myself . Please atleast suggest that what can I do.
I am literally sorry sir ! earlier by mistake I hv posted in Russian language which i was unaware of ..
I was telling sorry that such violation has been done from my side but it was all due to the code published in the public domain by me ..such thing will not be done from my side and thank u for the warning U hv given ....I will look into it very seriously from next time
I used ideone and totally unware about the fact that its a public domain. Sorry for the inconveniences caused, will use other ide from the next time.
Dear Codeforces Team, I am new to the Codeforces platform and recently participated in the contest where my solution for problems were flagged for similarity with several other solutions. I sincerely apologize for this incident. The questions were simple and could have the same logic and even I have submitted the code before the perosns whom I am flagged with so how can I copy them. Please its a request look into this matter. I am truly sorry for any inconvenience and confusion this may have caused. I don’t know how the codes are similar because even I have submitted the codes before them. I had no intention of violating the rules or sharing my solution. I assure you that I have learned from this experience and will be extremely careful in the future to avoid any such issues. I will ensure my code is kept private and secure moving forward. I have no issues in providing any explaination if needed as the rating is really important for me as it took a lot of time to come up with the working solution . Please reconsider your decision as I clearly have no idea who the person is and I have done my solution myself . Please atleast suggest that what can I do. I kindly request your understanding and consideration in this matter. Please just give my rating and submissions back for the Codeforces 955 div 3 contest. Also I am really sorry please don’t ban my account and if you can please give the submissions back for my contest. The contests are very important for me. I am committed to adhering to the platform's rules and maintaining the integrity of the competition. Thank you for your understanding.
Mail from System says.
Just make sure your solutions won't leak in future contests and you won't get punished and/or banned.
m sorry..wasn't aware of the ideone thing...thanks for informing that...after reading the your mail i checked the ideone settings and realised that its always on public mode...won't use it ever in future..please don't eliminate me for the contest..
I have recieved a notification regarding my submission 267383209 for the problem 1982B, in the recent 955 Div. 2, I would like to clarify that I haven't used any unfair means in writing the code, you can see the timings at which I submitted the solutions for A, B, C and D, it took significant amount of time to come up with the logic for B, maybe due to the non-trivial nature of B in this round, there is a similarity detected in the codes with others, it takes a lots of effort to increase the ratings, and it is highly demotivating if I am plagiarised on the basis of similarity in codes. I haven't used any unfair means for the above problem, and I would request not to penalise my account
Sorry but the way it implemented seems very similar to a massive leak :(
your code:267383209
leaked one:267358486
I hope you will reach expert again soon.
Sir, as I stated earlier, this was a bit ad hoc problem, and strategies of solving may have matched, but it was totally unintentional and I would look forward to it as a coincidence, but please dont penalise or block my account, I am sorry for any inconvinience caused..
Dear Codeforces I recieved this mail from your side : "Your solution 267373857 for the problem 1982B significantly coincides with solutions RohitSUS/267354420, notdilbarsl/267355396, Anshul1811/267358486, firrewghst_MQ/267358704,....." , I would like to clarify that I didnt used any public platform/ide or all and also didnt know about how my solution is found common to others, this was an easy question and I have written it totally by myself, I can clearly explain it's approach without any problem, kindly review it and give my ratings and submissions back, also one major proof of my innocence is the time it took to me to solve question B as that took my a lot of attempts to reach to that optimal approach
@vladosiya
i dont know that my code can be seen from public platforms
i was used ideone public mode i dont know some one can see my code you can see my solutions i wrote all of them on my own. from next time i will use my private ide
please dont skip my slotions and dont reduce my ratings
g.j
My code is original—I worked independently, using my unique approach. There's no intention or evidence of copying; any similarities are coincidental due to the problem's nature. I didn’t use shared platforms that could compromise my work. Eager to resolve this and maintain integrity. Fair review appreciated
The chances of it being a massive leak decreases by the fact that if it was a leak then why wasnt I plagarised for C too
Generally C problems are harder than B.It was a genuine solution and a mere coincidence.
Kindly look into it
.
Dear Codeforces Admin,
I received a notice regarding a significant coincidence between my solution (267350096) for problem 1982A and solutions submitted by users rajat_045/267347738 and kishan9936/267350096.
I would like to sincerely apologize for this incident. After reviewing the situation, I realized that I had used ideone.com to test my code and accidentally left the default settings on, which made my code publicly accessible. This was an unintentional mistake, and I had no intention of sharing my code or violating the contest rules.
I understand the importance of keeping my code private and secure. In the future, I will ensure that I use private settings on any online coding platform to prevent such incidents from occurring again. I am committed to adhering to the rules and maintaining the integrity of the competition.
Thank you for your understanding, and I apologize for any inconvenience caused.
No I havenot used any published source for the answers. Both are my own accounts ; sunny.nitnaware was created by me from my father's gmail account,where as my one is mine(2301mc44).As the ussernames of both the gmail ID's are quite same but [email protected] is of my father and [email protected] is of mine. I was trying to give contest on both the ID's at same time and that's why the cinfusion has been created.Iam very sorry for the inconvinience has happened. I havenot done cheating and havenot used any other sources for the contest.
sorry i was unawre about this next time i will not repeat this and take care from this time please leave me for this time.
wasn't aware of the ideone thing thanks for informing that after reading the your mail i checked the ideone settings and realised that its always on public mode won't use it ever in future please don't eliminate/ban me for the contes I am sorry for the inconvenience.
Dear Codeforces,
I received a notice regarding a significant coincidence between my solution (267072705) for problem 1986D and solutions submitted by user fomo_demod/267072012.
I would like to sincerely apologize for this incident. I dont know that my code can be seen from public platforms like ideone or gdb i used the public mode i dont know some one can see my code. It was a coincidence that my code mathched with the user fomo_demod/267072012. I will not do these mistake again i will keep all my online plaforms as private and i promise that this mistake won't be repeated in future any how. Please consider my request. please dont skip my slotions and dont reduce my ratings

Thank you for your understanding, and I apologize for any inconvenience caused.
Sorry, It was just a coincidence. The code I have written for problem 3 is a strategy. Icommon solve it on the ideone.I dont know about this can be accessed publicly .I will never use ideone again. I do not cheat, You can see my past record also. I am giving contests for a very long time. I always give contests with honesty. It was just a coincidence. I can tell you more about each and every step why I wrote that line. It has never happened with me before. I will make sure that this will never happen again . This will never happen again. I assure you that this will never happen again .
Dear Codeforces Admin,
I received a notice regarding a significant coincidence between my solution,
Your solution 267048071 for the problem 1986C significantly coincides with solutions Your solution 267373759 for the problem 1982B significantly coincides with solutions

In my last contest I write my code of 2 problem by myself and I can explain my code what I have done but it says that it is coincide..how I can’t know ..I see some of others code their concept is same but code is not same ..now what can I do
hello everyone, could someone tell me where i have to write a comment for replying on the act of plagarism
Where to post a comment regarding the unintentional same code even though there was no sharing of code?
today i got this message from Code-forces that my code {**1982B of contest 955 (div 2)**} is similar to many people (number is in thousands) which is just a coincidence. so i urge you to remove flag and give me my rating back. I have written that code on my own and as i was not known of codes get leaked from online ide (ideone.com) i use them to compile my code.
these are the numbers of contestants whose code is similar to mine and i do not know a single contestant from these.
i hope you will look into it and remove my plag and give me my rating back.
message i got. Your solution 267381758 for the problem 1982B significantly coincides with solutions RohitSUS/267354420, notdilbarsl/267355396, Anshul1811/267358486, firrewghst_MQ/267358704, yoshitha_13/267358897,

i will be aware from future but please this time give me my ratings back
i do not think that this much number of students can copy code from same place and the other thing is also we do not know each other. this is just a coincidence.
Dear codeforces , in last contest i haven't cheated or copied code from anyone, i know the person(NITIKA__) who copied code without knowing me , if you don't believe you can see my profile and no. of questions solved i think that will be enough to show that that much hardworking student couldn't even think of cheating . if you still don't believe me you can block me it's your company and your wish , i have gained that much knowledge to again reach to that rating . Thank you.
Dear codeforces team ,i accept that i have copied code in last contest from my friend shubham_sp without his permission ,i apologize for that ,you can take action on me as rule, but don't take any action or block id of my friend shubham_sp ,he haven't help me or send me code ,it is me that i have copied the code without knowing him as i have access to the platform where he write code before submitting , its totally my mistake . i promise i will not do any mistake like this further . thank you.
I dont know why i am getting this messege from codeforce.i didnot copy anyone code in that contest coincidentally my code match with them.i dont know any of them.**i want my rating point in that contest**.System

Dear Codeforces Team, I am writing to address the recent issue regarding the similarity between my solution and another contestant's. I want to emphasize that my code is the result of my original hard work and dedication. I do not know anyone else who participated in the contest, and I have not shared my solution with anyone. I am confident that my code was written independently and honestly. I kindly request you to consider my explanation and review the situation accordingly. Thank you for your understanding.
Dear Codeforces .I want to explain that the code I submitted is my own work. I don't know anyone else who took part in the contest, and I haven't shared my code with anyone. I'm not sure who copied my code, but I can assure you it was written by me alone.I don't know why I am getting this message..please give my remove the plag. i m totally unware of the matter and now i checked all my submission are skipepd? i don't know anything about it neither i copied. i dont know with whom my submission mathched but i think its a confusion. I did not do anything..so please remove the plagarism from my account Please consider my situation and review it. Thank you for your understanding.
I was notified that one of my submission was significantly similar to others. This was for the question 1928B during CodeForces Round 955. I disagree with this allegation as one can clearly verify my previous submissions for the same problem and can tell that I was trying to crack the code using similar approaches and when I was able to it was coincidently similar to others. I respect the decision yet, I would like to know how can one avoid such judgements by the system?
Attention!
Your solution 267384529 for the problem 1982C significantly coincides with solutions tikam/267373789, heyPaarth/267384529. Such a coincidence is a clear rules violation.

Got this mail today but I have not cheated or practiced any mal practices I don't even know the other guy. This is just a meare coincidence that our solution matched it was very obvious to use window sliding in that question and also our variables are different.I don't use online ides as such sometimes use programiz when vscode is slow or not working for some reason and also he submitted way before me. So it is just a coincidence that our code matched. Also you can check my previous approach for doing it. I was constantly trying to do that question and got error also in my first attempt.
Same happened with me, please give my ratings back.
I got the mail of plagiarism in the codeforces round 955(div.2) but the persons mentioned in the mail I don't know them and after seeing there code I realized there is much difference in there and my approach the basic thinking is only same but it doesn't mean that I copied from them I have my own thinking and I think they also thought in somewhat same way for that question but implementation is somewhat different. I also got negative rating in this round if I have cheated I would have done more questions to get higher rating. Please count this round I don't know how your system works but I will try to make my code and logic both unique from next time.
Dear Codeforces, @MikeMirzayanov I got one message that I got plagiarised solution for 1986E. I used a public website to write the program. At max that solution or that contest should be unrated for me but it should not decrease my rating by so much. Please take a look into it, I think there should be any problem in this. This rating is very important to me.
Dear Codeforces Admins,
I recently got a message that my 1982C solution, sriragt/267362951, significantly coincides with several other people's solutions. However, I believe my solution to this problem was a relatively short and straightforward two pointers approach that was replicated by many other submissions as well. I do not know any of these other people, and I believe that the similarity of our solutions is simply a coincidence because my solution is only 10 lines and there is not that many different ways to actually complete this solution. All of my code that I have written was created 100% by me, so I do not understand why my submission was flagged. Please let me know if you would like more information from me.
On problem 1989C I have notified about the solution coinciding with the other user. I don't know how it can be done because I guarantees you that I don't encourage any kind of malpractices. Maybe it is a coincidence and you can check my submission for 1989A and 1989B I have used similar variables and I have answered in different pattern from him. I think it is just a coincidence. I am assuring you that I am not guilty.
You got 2 more mails about interesting similarity in 2 problems:
267752955 267745184
267715040 267738104
sir i did not cheat....i instead used chatgpt as a reference to some problem.....I hope you return my rating back
Dear Codeforces Team, I am new to the Codeforces platform and recently participated in the contest where my solution for problems were flagged for similarity with several other solutions. I sincerely apologize for this incident. The questions were simple and could have the same logic and even I have submitted the code before the perosns whom I am flagged with so how can I copy them. Please its a request look into this matter. I am truly sorry for any inconvenience and confusion this may have caused. I don’t know how the codes are similar because even I have submitted the codes before them. I had no intention of violating the rules or sharing my solution. I assure you that I have learned from this experience and will be extremely careful in the future to avoid any such issues. I will ensure my code is kept private and secure moving forward. I have no issues in providing any explanation if needed as the rating is really important for me as it took a lot of time to come up with the working solution . Please reconsider your decision as I clearly have no idea who the person is and I have done my solution myself . Please atleast suggest that what can I do. I kindly request your understanding and consideration in this matter. Please just give my rating and submissions back for the Codeforces contests. Also I am really sorry please don’t ban my account and if you can please give the submissions back for my contest. The contests are very important for me. I am committed to adhering to the platform's rules and maintaining the integrity of the competition. Thank you for your understanding.
I do not know what is happening why i am getting contest violation message i can not see my code and they said you done cheating . It is not fair . The question in the contest is similar to one leetcode question that i solved previously . But i got contest violation i want to see my code and whom my code is get matched. I hope this comment will help me .[submission:267713749][problem:1989B]. If someone know how can i remove then help me
Dear Codeforces Team, I recently received a notification regarding a potential plagiarism issue for my solution to problem 1989A in round [Educational Codeforces Round 167 (Rated for Div. 2)], stating that my solution significantly coincides with that of another user.
I would like to clarify that I developed my solution independently without any collaboration or access to the other users' codes. I believe the similarity in our solutions is purely coincidental.I respectfully request the reinstatement of my rating and the resolution of this issue. Thank you for your understanding and assistance.
Dear Codeforces Admin Panel,
I am grateful that you have brought this to my attention. I get your point about the similarities between my code and others’. However, I would like to assure you that my submission was based on personal effort and it contained nothing against the rules.
Similarities can result from any reason such as standard ways of solving problems, same algorithms or even alike logical inferences from problems. Throughout all these contests, I have played fair by following the regulations and not using any unapproved resources.
If there is a particular part of my code that needs clarification, I will be glad to provide it. Competitive programming sites like Codeforces are very important for me due to their reliance on honesty in contesting.
Hope we can settle this dispute peacefully.
Yours sincerely, Aman
my solution 267748167 for problem 1989B accidently coincide with others pls don't reduce my ratings.This happened due to ideone,i forgot to change default settings of public .i will remember it next time
also my solution 1989A accidently coincide with others.what we can do.Please tell me.
Whether you cheat or not, that's your false.
Subject: Clarification and Request for Review of Plagiarism Allegation
Dear Codeforces Team,
I hope this message finds you well. I am writing to address the plagiarism allegation related to my submission for Contest 1989, Problem B. The submission in question can be found at the following link: https://codeforces.net/contest/1989/submission/267690782.
I would like to clarify a few points regarding my submission:
Submission Timing: I submitted my solution within 11 minutes from the start of the contest. This demonstrates my promptness in addressing the problem and should suggest that I did not have the time to copy from other participants.
Code Template: The structure of my code may resemble others' because I used a pre-prepared code template that I had sourced from a public GitHub repository before the contest began. This template is something I use regularly to streamline my coding process, and it might be similar to what other participants use.
No Prior Publication: I have not published or shared my code anywhere before or during the contest. The similarities, if any, with other participants' submissions are purely coincidental and a result of using common coding practices and templates.
I request a thorough review of my submission, taking into account the context and timing of my submission. I assure you that my intention was not to plagiarize, and I have always adhered to the integrity and spirit of the competition.
Thank you for your understanding and consideration. I am looking forward to your positive response.
Best regards,

Dear Codeforces Team,
I hope this message finds you well. I am writing in response to the notification I received regarding the significant similarity of my solution for problem 1989B with other users.
I would like to clarify that the code I submitted was entirely my own work. I have put in substantial effort into solving this problem, which is evident from the commented section of my code where I initially attempted a different approach. This demonstrates that I worked through the problem independently and logically arrived at my final solution.
Moreover, it should be noted that I successfully submitted a solution for problem C as well. From a logical standpoint, it would be unlikely for someone to solve problem C without being capable of solving problem B independently.
Additionally, my recent contest performance has been consistent and reflects my capability. I have achieved decent ranks, further indicating that my work is genuine and based on my understanding and problem-solving skills.
I kindly request you to review this matter with utmost care. I assure you that there was no intention of rule violation or plagiarism. I hope you will consider my explanation and avoid imposing any penalties.
Thank you for your attention to this matter.
Dear codeforces admins, My solution 267757500 for problem 1989C accidently coincide with Celestial_Wanderer/267754681. This happened due to ideone, I forgot to change default settings of public. I am new at this platform and don't know much about system. I will remember it next time. Please don't decrease my rating. The logic of the problem was pretty much easier.. we first read the number of people and their opinions about the two movies. We then calculate initial ratings for both movies by counting likes and dislikes. We identify people who like or dislike both movies, as they can be used to balance the ratings. After calculating initial ratings, we distribute the likes and dislikes optimally to ensure the ratings of the two movies are as equal as possible. The final step is to compute the company's rating as the minimum of the two balanced movie ratings, maximizing this value across all test cases. I will be glad to provide further clarification of my solution if you need. Codeforces is very important for me due to reliance on honesty in contesting.
Yours sincerely, Shreyas.
i use chatgpt for 268220733... it was not copied from someone...so please don't penalize me for that.
same
but can u tell me why your solution for D is same with alot of people getting skipped
same ..chatgpt...
Same
Dear Codeforces Team,
I am new to the Codeforces platform and recently participated in a contest where my solution for several problems was flagged for similarity with other solutions. I sincerely apologize for this incident and would like to explain the situation.
Firstly, I want to assure you that I had no intention of violating the rules or sharing my solution. I believe that the similarity might have arisen because I was using Ideone.com for coding, and unfortunately, the code was inadvertently set to public by default. As this was only my fourth contest on the platform, I was unaware of the potential consequences of using a public coding environment.
Furthermore, I submitted my solutions before the other individuals whose codes were flagged as similar to mine. This indicates that it would have been impossible for me to have copied from them. I can only assume that someone might have accessed my publicly available code on Ideone.com and used it.
I assure you that I have learned from this experience and will be extremely careful in the future to avoid any such issues. I will ensure my code is kept private and secure moving forward. The rating and participation in contests are really important to me as they represent significant effort and dedication. I kindly request your understanding and reconsideration in this matter.
Please let me know if there is any additional information or explanation you require from my side. I am committed to adhering to the platform's rules and maintaining the integrity of the competition. I sincerely apologize for any inconvenience and confusion this may have caused.
Thank you for your understanding and consideration. I hope to continue participating in Codeforces contests and improving my skills on this platform.
Best regards, Tarun Kumar

I request a thorough review of my submission, taking into account the context, logic used and timing of my submission. I assure you that my intention was not to plagiarize, and I have always adhered to the integrity and spirit of the competition. I am a deep lover of competitive programming any kind of these incidents will be harmful for my profile as I have given this profile in my resume as well.
Thank you for your understanding and consideration. I am looking forward to your positive response.

Solutions 268196680 and 268196560 for the recent Div1 and Div2 contest were both written by me. The 2002coder is my alternate account and during the contest I happened to submit the answer to B there instead here on my main account. I also wrote a mail clarifying the same to [email protected] on June 30, 2024 at 22:05 (UTC + 5:30hrs). It's been a mistake on my end and won't do it again but do not penalize me for the same.
Thank You

Subject: Clarification Regarding Solution 268190598 for Problem 1987D
Dear Codeforces Team,
I hope this message finds you well. I am writing in response to the notification regarding the significant coincidence of my solution 268190598 for problem 1987D with solutions ads.ok/268187912 and himanshu-0104/268190598.
I would like to clarify that I did not engage in any form of cheating during the contest. As a dedicated participant in competitive programming, I have been diligently improving my skills, particularly in dynamic programming (DP), through the TLE course. The problem 1987D is a DP problem, and I had encountered similar types of problems during my course.
I assure you that I did not share my solution with anyone. The similarity between my solution and those of other users could be attributed to the fact that DP problems often have standard approaches and solutions, which can lead to coincidental similarities, especially among participants who have undergone similar training or coursework. It is also possible that the other user(s) might have been part of the same TLE course or a similar learning path.
I understand the importance of maintaining the integrity of the competition and fully support the enforcement of fair play rules. If needed, I am willing to provide further details or evidence to support my explanation. Please feel free to contact me if there are any additional steps I should take.
Thank you for your understanding.
Best regards,

himanshu-0104
you know c++, go, ruby, javascript and c#. Are all these languages taught in the course or did you learnt them by yourself
Regarding your query, I love to explore programming languages. Over the years, I have learned several languages, including C, C++, Go, JavaScript, Python, Java, C#, Kotlin, PHP, Ruby, MATLAB, and Rust. I am currently exploring Dart, Solidity, and Vyper.
Some of these languages were part of various courses I took, while others I learned on my own through self-study and practical projects. My passion for programming drives me to continuously expand my knowledge and skills across different languages and paradigms.
yeah thats why u are getting skipped lol...
Dear Codeforces team I am new to the Codeforces platform. I recently participated in the contest where my solution was flagged for similarity with other solutions.I am truly sorry for this incident. I had no intention of violating the rules. I have learned from this experience. I will be careful. I kindly request your consideration and understanding in this matter.
Dear Codeforces Support Team, I am writing to inform you about an issue regarding the unintentional leakage of my code during recent contest. I want to clarify that I did not intentionally share my code.I used OnlineGDB to check my code during contest,unware that it might be publicly accessible by default. I assure you that I have taken measures to prevent this from happening again,including using a local development environment for future contests. I sincerely apologize for any inconvenience this may have caused and request that you reconsider any penalties or actions taken against my account. Thank you for your understanding.
Dear Codeforces Support Team "I apologize for the significant similarity between my solution (268208528) for 1987D - World is Mine and others'. My approach was based on my personal understanding of programming concepts and my own strategy. I did not intend to replicate any other solution, and my submission stemmed from creative thinking and prior knowledge. I assure you that I will be more cautious in the future and avoid relying on unauthorized sources during competitions." Thank you for your understanding
Dear codeforces team,
I was out out of town, and was not able to see my notifications. I just noticed that my ratings have been rolled back because of my similarity to other users . I can assure you that in no manner have I copied from any of the users, and I believe my record of contests can vouch for the same.
I was sent the message: Attention!

Subject: Clarification Regarding Solution 268177288 for the problem 1987B
Dear Codeforces Team,
I hope this message finds you well. I am writing in response to the notification regarding the significant coincidence of my solution 268177288 for the problem 1987B.
I would like to clarify that I did not engage in any form of cheating during the contest. As a dedicated participant in competitive programming, I have been practicing a lot and I want to clarify that my solution/logic is kind of similar with Largest Sum Contiguous Subarray(Kadane's algo) and many other problems like that and I got the reference from that only: https://www.geeksforgeeks.org/largest-sum-contiguous-subarray/
I wrote the code myself and didn't copied from anyone. I assure you that I also did not share my solution with anyone. The similarity between my solution and those of other users could be attributed to the fact that the solution is based on some standard approaches and solutions, which can lead to coincidental similarities, especially among participants who have undergone similar training or coursework.
I understand the importance of maintaining the integrity of the competition and fully support the enforcement of fair play rules. I request a thorough review of my submission, taking into account the context, logic used . I am a deep lover of competitive programming and any kind of these incidents will be harmful for my profile.

First contest-
Your solution 267734833 for the problem 1989C significantly coincides with solutions _swapnilpandey_2210/267734833, kanikaa/267742452. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.

In case of repeated violations, your account may be blocked.
I actually don't know how the codes matched. Yes, we practiced the CSES problem sheet together and many questions are similar to those published in the contest. Also I think that someone leaked it using the hacking room and that is why the code matches exactly. Please try to improve the hack room system during the contest. Please remove cheating mark from the codeforces account as it is so valuable for me.
Join AntiCheaters for support!!!
Also I'm going to downvote most of the appeals here because these are meaningless and troll-like.

This in regard for the my solution to problem 1983D of Round 956 (Div. 2).
I got a notification regarding my the coincidence of my solution 269270131 with 269259042. This was due the coincidence of the algorithm used in the problem, both were taken from this source link. I had even mentioned the source in my submission. I wrote rest of the code myself. Also the style of writing the code matches with my previous submissions.
I request the Codeforces Team to review my submission. I have also posted about this in the contest blog.
MikeMirzayanov, Vladosiya and the Codeforces team.
Please look into it, as said in the rules i was only just using code published before the start of round.

Thank you for your attention to this matter. I look forward to your response.
i used idone i am new at this website after practising in leetcode, i try few contests there are no such suspicious activites in my account
Same Thing
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured. Please give my ratings back
My solution https://codeforces.net/contest/1983/submission/269278403 got skipped telling in has significant match with https://codeforces.net/contest/1983/submission/269258951 this solution. But the two functions minSwapsToSort() and minSwapToMakeArraySame() was copied from geekforgeeks https://www.geeksforgeeks.org/minimum-swaps-to-make-two-array-identical/ . Our main functions are even different. Hope codeforces will take steps as soon as possible.
This in regard for the my solution to problem 1983B，C of Round 956 (Div. 2).
I got a notification regarding my the coincidence of my solution 269289896 and 269293704 with 269282646 and 269287450. This was due the coincidence of the algorithm used in the problem, both were taken from the same place and they have same skill. I had even mentioned the source in my submission. I wrote rest of the code myself. Also the style of writing the code matches with my previous submissions.And the same time I am a new user for codeforces which make me cannot know many rules about codeforces.Maybe I did some things make my code become publicized.
I request the Codeforces Team to review my submission.Please for give my ignorance, I do not want to restart. ~~~~~

Same thing happened
I am sorry for my mistake. I used ideane.com and programiz c++ online compiler so the problem occurs. In the future such mistakes will never happen again. Please forgive my mistake. Thank you.
I never cheated or copied from others and there is some difference in our but still we got coincide it may be miracle but i wanted to confirm that i don't them at all and we are completely strangers never known but if it coincided is it right to skip their solutions
Thank you for bringing this matter to my attention. I want to address the allegation regarding my solution for problem 1983D. I assure you that I have never cheated or copied anyone else's work.
While my solution coincides with others, I can only attribute this to the possibility of common logical approaches to the problem. We are completely unconnected, and I have no prior knowledge of these individuals or their work.
I kindly request a thorough review of all test cases to verify the originality of my solution. I am confident that this will demonstrate that any similarities are purely coincidental. This situation has unfairly affected my ratings, and I respectfully request a reassessment to restore them.
Thank you for your understanding.
I have participated in Codeforces Round #956 (Div. 2) and ByteRace 2024 and in question B ,I don't how my solution was leaked. I think by using ideone.com and I was't aware of that. Next time, I will take care and will not use these websites. Please didn't reduce the rating. These ratings are very precious to me.
Hi, it was a coincidence that my solution 267393926 for the problem 1982B coincided with one other solution as I wasn't aware of ideone.com with the default settings because my local IDE wasn't working properly. It was just a coincidence. Sorry for using ideone.com with the default settings. Can I get my ratings back? From now I'll use sublime. Thank you.[contest:1982][problem:1982B][submission:267393926]
Dear Codeforces team, Please look into this matter because the problem 1982B itself states that there are three integers x, y and k. And are chances that the other's solution 267373281 for 1982B have used the same approach like mine one. I haven't cheated and this was just a coincidence or may be due to using variables mentioned in question 1982B itself or may be the other user had the same approach as of mine.
I can determine, if you have a cheated on not. Just do a small favour for me. Solve 4A - Watermelon question by own (using ideone in c++ and share that here). Then i will determine if you are a cheater or not in 5 sec.
https://ideone.com/7rgCDf#cmperr So, what after this??
Ideone recently changed their default settings from public to private sir
Don't know about that sir. I switched to my local ide from last contest and was able to solve only question'A' but I'm quite satisfied because I wrote that code by my own approach.
Your solution 269276044 for the problem 1983D significantly coincides with solutions abo_kamal/269276044, saksham_21/269285025, LCS2022003/269285636. Where is the similarity in the solution to skipp my solution my?
g.j
This same thing happened with me in the last contest. I wasn't aware that such things can happen too, I'll take care of such things in the further future! Also I want to clarify that the code that I have submitted is mine and it wasn't copied from any source. I respect the integrity of codeforces and its contest rules.
It is a standard bfs problem how can it be considered be cheating
same thing happened with me i have use segment tree code in question d thats why i think my code is skipped i request to please look into the matter . i dont understand that why codeforces apply plag on standard problems ,there are some chances of similarity it doesnt means that we have cheated .
Ideone recently changed their default settings from public to private.
I have received a mail stating that my solution 270006582 for the problem 1992D significantly coincides with other solutions.
I used a greedy approach for this question and it happened to be similar to others. It was my approach and solution. I ask you to reconsider me because none of my submissions other than the one flagged are similar to any other submissions. Moreover, all my previous submissions follow the same patterns and style of coding. It is purely a coincidence in my case. I am committed to making the contests fair and following codeforces rules and guidelines.
Dear Codeforces Team,
I recently received a notification regarding a significant similarity between my solution (270013873) for problem 1992C and solutions satwikr78/269987042, ASA_HELPER/270013873. I want to clarify that my solution is independently written and not copied from anyone else. In my solutions for problem 1992C, it can be seen that I was figuring out multiple approaches to solve a problem. I used a programiz online compiler to write and test the code for given test cases. Here are some key points and evidence to support my case :
Link to submissions: https://codeforces.net/submissions/ASA_HELPER/contest/1992
I hope this explanation provides clarity on the situation. I assure you that I follow the Codeforces rules and maintain the integrity of the competition.
Dear Codeforces Team,
I would like to address the concern regarding the significant coincidence between my solution for problem 1992D (solution ID: 270042921) and the solutions submitted by Karthikeya__00 (solution ID: 270002446) and mthirumalai2905 (solution ID: 270042921).
I have been using ideone.com to test and run my code. Unfortunately, I was unaware that using ideone.com with the default settings makes the code publicly accessible, which might have led to someone copying my solution without my knowledge. I assure you that I had no intention of violating any rules and did not share my code deliberately.
I understand the importance of adhering to the competition rules and will ensure to use private settings or other secure platforms for my future submissions to avoid such situations.
Thank you for your understanding.
Best regards, mthirumalai2905

My solution: 270723087 The other person's solution: 270705131
Again, "your solution coincides with..."
1- Although the logic is the same, my code is definitely different from theirs. 2- The system only detected similarity between me and them.
I just want to know how and why did it even get detected. I get that the logic is the same(as it should be since that's how this problem works), but it's not like my solution is 90%+ similar. I mean at the end of the day it happens that 2 or more people have nearly the same code out of all of the people that submitted. I mean I get that if the code is pretty much similar or exactly the same, but not in this case. I would like to get my rating back, thank you.
I wasn't clear on the "again" part. This is the second time such a thing happens to me and it is a bit annoying since it just doesn't make sense at all.
Dear Codeforces
I don't know what happend but i think my account was hacked. I saw a mail from 1 july says someone logged in my account.Though I did not saw that mail because of my neglegence but as today I checked and saw these mails. Then also got a message from codeforces maybe my account password was leaked. So today I changed my password. I don't know how it happend. please see the matter and don't take my ratings back.
Sorry, I published my code on ideone.com that's why the system saw the similarities. Please give my ratings back
I have not coppied or used any source, i have written the code same as i used to write but don't know how the code matches with others this is surely a mistake please, look into this matter Codeforces Round 959 sponsored by NEAR (Div. 1 + Div. 2) 271255666.
Please give my rating back it is a huge affect on my rating
I apologize for revealing my code
Same things happened to me,but i do not know.
Actually, I don't know how my code got shared. I did not share my code with anyone, nor did I use a public IDE to write my code (I use a local IDE, Sublime Text, for writing code). However, my code is visible to my assigned room members(codeforces room).
Thank you.
i was writing the code in ideone and i wasn't aware it was in public mode. I apologize for my mistake and will never do again as it was my initial contest i was not aware about i will not repeat the same mistake
I accidentally made my code public while using Ideone. This was my first competition, and I didn't realize it could be an issue. I apologize for my mistake and will be more careful in the future to ensure this doesn't happen again.
This was my first competition, and I unknowingly copied public code on Ideone. I apologize for any issues this may have caused and assure you that I won't make this mistake again.

I have generated the code using chatGPT, which I am sure is perfectly fine.
Here is the link to my conversation with ChatGPT:- https://chatgpt.com/share/21a15704-0cda-45cb-a5ed-fbae157e94c0
All the submissions I have made during the contest have been Skipped.
Please resolve this matter.
Same thing happened to me.
The matching code for this question (https://codeforces.net/contest/1995/problem/B1 ) is just a coincidence. It was a basic question, and I didn't use any unfair means to generate code or copy code.
Compairing 272163836 and 272101512 I see that even empty lines are the same.
Please see all my previous submissions. I use the same code flow and gaps to make the code clearly visible. Similarities in variable names and conditionals are as per the question. If I had used random variables, then you could have believed it.
Hi, in the contest "Codeforces Round 962 (Div. 3)", my solution 272814471 for the problem 1996F significantly coincides with others, but this solution was written by me in https://www.acwing.com/activity/content/code/content/7949410/ on March 5th, 2024, in other words, this is my own code, so I didn't break rules, I sincerely hope that my solutions in this contest won't be skipped.
Same thing happened to me, I did write the code of 1996D and then furnished using ChatGPT, which is not wrong obviously, also, my compiler was providing some issues and so I used online compiler for the contest. I am extremely sorry that this happened and my ratings are taken aback of div3. Please give me back my ratings, I did very hard work to get to pupil, now I have reached here but if this happens my confidence will be shattered, kindly look into this matter.
Also, the problem did have a simple math logic and hence it maybe obvious to have significant similarities with other code, please don't take my ratings away. It is a request, the thing was totally unintentional.
https://chatgpt.com/share/565865b3-615e-4c57-a970-05b3b644a566 Here is my conversation with GPT, for further furnishing, please look into this matter.
Your solution 273191015 for the problem 1991B significantly coincides with solutions Frizzest_99/273180651, ArjoKar11_01/273191015. Such a coincidence is a clear rules violation.

The code is done by me, GPT helped furnishing, I didn't copy from anybody's code. Please look into the matter
Hello, in the contest Pinely Round 4 (Div. 1 + Div. 2) my submission 273218941 has been detected similar to others.
I want to clarify that this code was completely written by me in VS code and it can be seen through my submission history that I tried various approaches for the same question. Initially I was trying to use the Sieve of Eratosthenes coupled with other algorithms(such as bfs) to try to solve the question. When that didn't work I realized that the solution has to be of the time complexity < O(n^2). I searched on Google and came across the Four Colour Theoram and Chromatic Number of A Graph. I went through the above articles and then solved the question by hardcoding for n = 1 to n=6 and further on by pattern printing.
All of my submissions of the contest have been skipped even though the similarity of the codes was a complete coincidence. One key difference between my code and those that have similar ones to me is the fact that almost all of them got submitted in one or two go and have a boolean function checking whether a number is prime or not that is never being called. However in my code, I have only the sieve function(**which was present in all of my previous solutions**) which I never deleted in the first place because I forgot to. This shows that I was manipulating my code only.
Please look into it as I never copied the code nor did I give my code to someone else.
Thanking you, Ayush
in contest pinely round 4 (div1 + div2)
Question N0 : 1991C
I think my code on ideone.com was published in public. Here after it won't happen. Sorry CodeForces.com
Dear Codeforces Support Team, I am writing to inform you about my code 272810561 in Codeforces Round 962 (Div. 3).The F problem 1996F - Бомба come from 13rd lanqiao contest which was launched two years ago. And that problen was recorded in acwingthis website.These two problem is same entirely.Because I had written it several months ago.For convenience, I just copy the code to this round. However the solution code for that question are almost the same acwing.So that's the reason why some of us had same core code. So wish codeforces support team can giving back my ratings.Thanks.
Today's i received a message from the system for same code but i haven't copied any code during contestant. But sometimes i am using online compiler. 1996E question. Sorry for that, please give penalty for that mistake but don't blocked my account or degrade rating. It's never happened again from my side. Thank you.
I dont know how but my solution of problem 1991D is copied by some one and i got plag message worst plag checker it has.
I'm sorry but that was a coincidence, my solution to C in the latest pinely (div1+2) contest is reasonable (i came up on my own as the states cannot be stored on two separate arrays) (still got skipped) and i want to get my innocence back
as for rechecking, I am not clear. I have not referenced the code on any platform, nor have I submitted the code on any platform except CodeForces. Please restore my score.

I used ideone for the first time and had no idea about settings that it has option of public.I apologize for my mistake I will not repeat it again.
when I'm not home I usually use IdeaOne ,I have been used it for along time and I swear I don't know that it act like "cheating" for some divs ,I have receive a massage that my code for Round 963 (Div. 2) for 274412931 for problem 1993B coincides with a lot of codes, I got lost my points and don't understand why but now I search and read all the mail so understand that it may possible to share codes public,thankyou in advance.[contest:274412931]
I usually code on sublime but at Codeforces Round 963 (Div. 2). I didnt have my laptop so I used my sisters laptop to code on ideone.com since she didn't have the sublime setup on her computer. I had no clue about its public visibility. Please, give my ratings back this is not fair I worked hard for this and you guys are taking it away from me. That's not fair!!!
Attention!
Your solution 274390449 for the problem 1993C significantly coincides with solutions Hafeezgrandmaster/274390449, yashmaini/274396584. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
I dont know how it happened neither i took code from someone nor i send someone iam sure it is just a coincidence please delete the above message from my talks
so sorry
it has been a problem because i used an extension in vscode that was generated next possible line and also gave perfect format, and that the only logic to the codes i was able to think coincided with the others ,
i assure you that i havent cheated or any other sort of violation
i dont know how the codes were same..but next time ill manage to write a code without formatting and really weird variable names.
I received this "Your solution 225150510 for the problem 2002D2 significantly coincides with...". I would like to make it clear that I was using Ideone. However, I didn't realize it was in the public access mode(I regularly use sublime text on my local PC with my custom template as in my solution). You can check all my other codes and previous submissions to verify my solution. I even use my same template on one of my other accounts. However, I was facing some compilation issue so I once used Claude to do the minor fixes. This is a carelessness from my side and I can assure something like this won't happen again. Therefore, I would request that my solution not be skipped. Please let me know if any additional information is required.
You can check my other account here
I have been doing codeforces for more than 3 years and have been around a similar rating solving more than 700 problems. I can assure you it was my own hardwork and a bit of carelessness.
Thank you for your consideration.
Apologies for the confusion and my mistake in using IDEONE ( as my gcc compiler was not working) for the latest div 1+2 round (2002) where my submission for D2 seems to be copied a lot by others due to the default public setting. I assure that I did not purposely do it and as evident from my profile, I have no previous record of cheating and had no intention to spoil the codeforces platform. Hence, I request you to reconsile the decision of skipping my contest and making my submissions valid. I assure you that such a mistake won't happen again from my side.
Thanks for considering.
Dear Codeforces Team,
I hope this message finds you well. I am writing to address the recent concern raised regarding the similarity between my solution to Problem 2002D1 2002D1 - DFS Checker (Easy Version) and another user's submission. First and foremost, I want to express my sincere apologies for any issues this may have caused.
I would like to clarify that the solution I submitted was the result of my own efforts and understanding of the problem. I did not intentionally copy or replicate any code from other users, nor did I engage in any form of collaboration or sharing of code with others during the contest. I understand the importance of maintaining academic integrity and the values of fair competition, and I deeply regret that my submission has raised doubts about my adherence to these principles.
In retrospect, I realize that my approach to the problem may have inadvertently led to a solution that resembles others. This might have occurred due to the common logical patterns or coding practices that many participants may follow when tackling similar types of problems. However, I assure you that my work was done independently, and any similarities were purely coincidental.
I take full responsibility for this situation and appreciate the vigilance of the Codeforces team in maintaining the integrity of the platform. Moving forward, I will be more mindful of how I approach problem-solving to ensure that my submissions are distinct and reflective of my individual effort.
Once again, I apologize for any inconvenience this may have caused, and I am fully committed to upholding the standards of the Codeforces community. If there are any further steps I need to take to resolve this matter, please let me know.
Thank you for your understanding and consideration.
Hello sir, I have got an email saying my solution #275819490 coincides with[contest:2002][submission:275819490][user:aditya_kh7503] someone, although i did the whole problem myself, i have attached my solution that i pasted on the ideone and i have attached the proof of my code on the platform, please don't remove my rating and please removeYour text to link here... plag from my solutions.
Your submission page fill up with skipped and now come to defend, hmmmmmm
Dear Codeforces Team,
I trust this message makes you well. Regarding allegations of plagiarism in my solutions to Problem 2002D1 — DFS Checker (Easy Version) and Problem 2002D2 — DFS Checker (Hard Version ). These are My Solution of Problem D1 Submission #275824981 and Problem D2 Submission #275825300 regarding Div 2.
Rest assured, I made every attempt to resolve each issue in isolation. I have solved to the best of understanding I can and did not copy or knowingly replicate any other users codes. Like I said, while my solutions might seem similar to how someone else achieved a solution coincedently as well. The problem was such that it is possible others might have landed at the same approach. But the my code is completely different from what others you have flagged.
Now I know though that possibly having my code seen by the public due to using Ideone as it is also might have made similar coincidences happen. That was not my intention and I do apologize if its come out as a mix-up.
I wholeheartedly admit that this was my fault and I'm grateful to the Codeforces people for monitoring such nefarious ways of obtaining high rating positions. I will be more cautious about my code in the future, as well to protect myself and ensure that what I submit is truly a work of utmost individual effort.
Apologies again for any confusion here, and I fully committed to upholding the standards of the Codeforces community.
Got mailed for 2002D1, EPIC Institute of Technology Round August 2024 (Div. 1 + Div. 2) Aug/11/2024 17:35 Sorry but it was a coincidence. I was using ideone.com and wasn't aware that it is in public mode. Will never repeat this mistake. Sorry for that.
I'm really sorry for the issue during the contest. I usually code in the CodeChef editor, and I was able to solve the initial questions without any issues. However, after some time, the editor page stopped loading properly. In a rush, I decided to use Ideone and forgot to adjust the settings. This was my first time encountering this problem, and I had no idea that others could access my code. I sincerely apologize for this mistake, and I assure you it won't happen again. Please understand that this was unintentional, and I kindly request that you don't impose any penalties or block my account. I've really worked hard to get to this point, and I genuinely didn’t know. It was my mistake, and I accept that. I promise it will never happen again.
I would like to clarify that I used ChatGPT to help me with problem E and F. This may have led to my code being flagged as similar to the aforementioned solutions. While I am not certain if using ChatGPT violates the Codeforces guidelines, I acknowledge that the blog entry mentioned in your email states, "the code is generated using tools that were written and published/distributed before the start of the round," as an exception. I am extremely sorry for this oversight and assure you that I will not repeat this mistake in future rounds. I
I sincerely apologize for the issue that occurred during the recent contest. I used Ideone, but it was mistakenly in public mode. This was my first time encountering such a problem, and I now understand the gravity of the situation.
I assure you that this was entirely unintentional. Additionally, I referred to some online articles during the contest, which I now realize might have contributed to the issue. I deeply regret this oversight and promise that it will never happen again. I’ve worked incredibly hard to get to this point, and I genuinely didn't mean to violate any rules.
I also have proof of the rough work I did while solving the contest, which I can provide if needed. Please understand that this was an honest mistake. I kindly request that you consider this when reviewing my case and hope that no penalties will be imposed on my account. I am fully committed to upholding the integrity of the platform and will take extra precautions to ensure this doesn't happen again.
Your solution 275838441 for the problem 2002D1 significantly coincides with solutions gaosichen/275830114, beiwen/275838441. It's my fault,I used gaosichen's computer and logged into my account to submit the code while he was away.
It was really a coincidence , you can check my previous submitions on the same problem E , I was a half hour trying , I just do a precompute . Please Give me my ratings back again .
cheaters should be banned
Code i have submitted is completely written by me , this is just coincident as the implementation of the solution is very straight forward.
I assure you, this thing will be never happen in future.
I have been using online compilers to run my code since the start of my competitive programming journey because my VS Code was not running all the test cases properly. So, I switched to using online compilers. Today, I received an email from Codeforces stating that my solution was similar to another user's, and I realized that this might be due to the online compilers I use during contests, specifically ideone.com. I was unaware that the code could be copied from there. I have proof that I have been using that website for a long time, and nothing like this has happened until now. However, from now on, I will switch to a more secure method for coding during contests. here is ss of the website
MikeMirzayanov please look into this matter
Your solution 274818786 for the problem 1999D significantly coincides with solutions prathambhushan04/274818786, Eagle_786/274892850. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation.
I have just checked that all my solutions for the contest got skipped, I don’t know why but I didn’t do anything wrong. Please it was coincidence I don’t know the other person.
Sorry for the mistake i did by using ideone.com
Hello, whoever is reading this I have just received the mail regarding the submission 274835446 that this solution is being coincided with the other mentioned users in the mail. I want to make one thing clear that the solution which I have written for the problem is very intuitive. The idea for the had directly clicked at the time of solving the problem and I am absolutely sure that nothing was leaked from my side nor did I make a violation of any rules.
The users mentioned in the mail, I checked their profiles and they have not given even 5 of the contest properly. As a respectable part of the CP community and active on the platform for the last 1.5 years I assure you that nothing was compromised from my side. I respect the community and rules and have never violated the rules and nor will I in the future. Please whatever the misunderstanding is there, solve it and consider my solution to the Problem as accepted.
I am happy to provide you with any other information you need. Thank You.
I wrote the solution entirely by myself, and I am more than willing to explain my code and reasoning if needed. If there was any unintentional leakage, I assure you that it was not done on purpose, and I will take the necessary precautions to prevent this from happening in the future.
Please do not block my account or impose penalties, as this was an honest mistake, and I was unaware of the potential consequences. I greatly value my participation in Codeforces contests and would appreciate your understanding.
Thank you for your time and consideration.

Subject: Clarification Regarding Suspected Code Similarity in Problem 1999D [Codeforces Round 964 (Div. 4)]
Dear Coordinator (MikeMirzayanov, SlavicG, flamestorm, mesanu),
I hope this message finds you well.
I am writing to address the recent notification regarding the significant similarity between my solution (Rarma/274889445) for Problem 1999D and the solutions of other participants.
First and foremost, I would like to state that I did not engage in any form of cheating or code-sharing during the competition. I take the integrity of my work very seriously and understand the importance of adhering to the rules.
I have reviewed my code and compared it with the solutions with the other participants like TEKNAS2005/274951090, krizsu/274779701 , etc and there is no similarity with my code you can aswell check it with other participants also. also i submitted one wrong solution and then corrected my mistake and submitted the next solution you can compare both the solution submitted by me Rarma/274832015 [ WA ] -> Rarma/274889445 [ AC ] I also commented multiple codes which i stumble upon while solving question. While there may be some resemblance in the structure or approach due to the nature of the problem, the code itself is original and was developed independently by me. Given the nature of competitive programming, it is possible that participants might arrive at similar solutions, especially if the problem has a straightforward or common optimal approach.
I assure you that I did not access or share any code with other participants during the competition. If you require any further explanation or evidence to support my claim, I am more than willing to cooperate fully.
I kindly request that you review the situation once more, taking into consideration my explanation and the differences in implementation that may exist upon closer inspection. I highly wish this problem to be resolved and if you find my code similar to anyone of other exactly same then please tell me otherwise please remove this false accusation
Thank you for your attention to this matter. I hope for a fair resolution.
Best regards, Codeforces Handle: Rarma Username: Rarma
I also got that warning. But the actual code is written by me. Whoever copied my code I didn't know this actually but I can assure you that the code is wrote by me. You can also check the wrong submission history and the similarity between those code written by me. And as it is my code I can sure it is submitted first by me. The problem is 1999D.
I use ideone. I just got to know about this thing.
Hi MikeMirzayanov I am writing to address the recent notification regarding the significant similarity between my solution (yessirski/274919032) for Problem 1999E and the solutions of other participants. My solution use a piece of my pre-written Prefix sum which is stored publicly here. As you can see, my other earlier TLE submission is about by not using this prefix sums trick. Thank you for your attention to this matter. I hope for a fair resolution.
Thanks
Hey MikeMirzayanov, don't even know if you will read this comment or not, but still hope that. Today I received mail regarding there is similarity between my code and a bucnch of usernames/submissions whom I don't even know. I have the code all by myself in the ongoing contest in my VS Code editior only.
Codeforces Round 964 (Div. 4) Problem D Slavic's Exam : 1999D - Slavic's Exam My solution was : 274868344 code :
Here is what my Logic was: 1. Created a boolean vector for storing the second string's letters' presence in first string. 2. 1st for loop through 1st string increased second string's pointerif second string's letter is in first string or if first string's char is '?' then replaced '?' with second string's letter and incremented second string's pointer. 3. 2nd for loop: here I checked for string s2 in string s1 and as I found the letters of s2 in s1, I marked the boolean vectors respective index as true. 4. in the 3rd for loop: if there were any remaining '?'s in s1, i replaced them with 'a' (well , most of coders who want to remove some '?' and replace it with only lowercase letters will first think of 'a' Or 'z' and this is the only thing that you system seems to give me the tag of suspicios submission ) 5. At last I just needed to check if the boolean vector is all marked with true or not(based on my code if last index of vector is true -> whole vector is true).
I don't use any online IDE for running the code on my end before submission, i use VS code.
The 4th step mentioned above was what was missing from my 1st submission where I divided that solution into two parts(which wasn't needed as I later figured): 274830513
And finally come on man, this wasn't that hard problem to come with solution , Just had to skip the letters in s2 and replace the '?'s in s1, that's it. I request you to got through my profile once and see for yourself If you think I can cheat on this code or Not. I hope the admins read this comment of mine and remove the skipped tag from my solutions.
Sorry Codeforces Community
Sorry if this is already answered in the text above, I'm not quite sure
i didn't know that somebody can see my solution ,
I use ideone. I was not aware of this. Please don't block me or give penalty as I wasn't aware it was in public mode. I apologize for my mistake and will never do again.
EclipseWraith a moment ago, # Edit Delete | Add to favourites Vote: I like it 0 Vote: I do not like it Subject:** Urgent: Unfair Penalty for Problem 1998D
Dear Codeforces Team,
I hope this message finds you well. I'm writing with a heavy heart regarding the recent issue flagged for my solution to problem 1998D. The notification states:
*"Your solution 275630271 for the problem 1998D significantly coincides with solutions [user:razz_11]razz_11/275627442, his submission
EclipseWraith/275630271."my submission
I want to clarify that the solution I submitted was entirely my own work, and I have no connection whatsoever with the other participants involved.
With a contest involving around 30,000 participants, isn’t it plausible that solutions with similar logic might emerge, especially when we all are tackling the same problem? It’s disheartening to be penalized for something that’s beyond my control. My code is not even close to the ones it’s being compared to, yet I’m facing the possibility of penalties that could significantly affect my time, efforts, and rating.
I understand the importance of maintaining fairness and integrity in these competitions, but I assure you that my intentions were honest, and I have always followed the rules. It’s upsetting to see my hard work and dedication being questioned due to circumstances that I didn’t create or contribute to.
I request you to please reconsider the decision and review my submission carefully. I’m confident that you will find no malintent on my part. This issue not only affects my rating but also demotivates me from participating in future contests.
MikeMirzayanov ,Vladosiya, I know you might receive many such messages, but this truly affects participants like me who put in a lot of time and effort to compete. If this issue cannot be rectified, it may lead to many users, including myself, considering a shift to other competitive programming platforms where such occurrences are handled with more nuance and fairness.
Thank you for your understanding.
Such a coincidence twice. Nice story 😀
I am not saying about the contest 2002. idiot!
Means you cheat always but wants to be guilty sometimes
This is regarding the solution of problem 1999E, which is 274942060. I didn't know how this happened I wrote the whole code on my own. I used an online compiler; I don't have any idea about whether that was public or not. if you need any kind of explanation I can give you that. Please don't block my account or please don't imply any penalty. sorry, codeforces.com next time, I will be aware of using any kind of compiler for any websites.
also, I generally use vs code, but at that time, some error occurred, that is why I used an online compiler at the last minute.
I used ideone as I was not aware as it is not allowed. I would take care of that in future, Team.
Dear community,
Last night, I received an email stating that my submission for problem 1999E i.e. 1999E - Triple Operations was found to be similar to someone else's submission. I want to clarify that this was a very simple question with over 8,000 submissions, and it follows a very common approach using precomputation with prefix sums, which anyone could think of.
Before the submission that caused my contest to be skipped, I made an earlier submission 274863303 that resulted in a TLE on some test cases. Even a basic programmer can understand how to eliminate such a TLE when you need to calculate the count of how many times a number is divisible by 3. Initially, I was performing these calculations for every test case, but later I optimized it by using the precomputation technique with prefix sums to calculate the required operations for each number. Here is the submission link 274886104.
In the submission, you'll see that this is the same logic you even posted in the editorial of the problem. I have not found a different solution so far. Upon reviewing other submissions, I believe that my submission matched with someone else's simply because they also used similar variable names. This seems to be a coincidence, as terms like precompute, prefixSum, and operations are very common and could easily be suggested by the autocomplete feature of any IDE.
Dear MikeMirzayanov, I kindly request you to look into this matter and remove the skip on my contest.
rroushan14/276252495, 2000E — question
above mention the same code, this is my account. Today's i received a notification from codeforces, my code is matching with the other users, But i have not done any copy of code / violation of contest. I have proof that , i have used chatgpt to optimize the code but not copy from anyone. I have attached the chat link, you can verify that. Don't degrade / block my account @admin codeforces. Please don't degrade my ranking.
chat link : https://chatgpt.com/share/bfa6be57-d6da-47c2-8ec3-1640a1219924 Dear MikeMirzayanov, I kindly request you to look into this matter and remove the skip on my contest.
Hello, I used some references from here to solve the problem. Even it's not fully published here. I received plaig for the same i guess, I used it for reference to solve the code. It was published before the contest.
https://www.hackerearth.com/practice/notes/dynamic-programming-problems-involving-grids/
I'm quite new to cf and haven't participated in many contests. A friend recommended ideone.com to me, so I used it without configuring the settings properly. I apologize for any issues that may have caused.
Hello MikeMirzayanov or anyone else from codeforce team, today I received mail regarding plag for 276172939 which is a mistake. The ques have very simple logic that I used GPT to save time
While I can't share the original GPT link as it has image & as per GPT "Sharing conversations with images or audio is not yet supported", After multiple try, I was able to get GPT to generate 100% same sol which I originally got
Used GPT4-o: https://chatgpt.com/share/e4f08db7-fc07-458c-8d54-8439d4c125ae <- last sol. It took multiple try but I was able to recreate what I got before
I even try basic GPT4, and even it was able to correctly generate sol (not 100% same, but close enough): https://chatgpt.com/share/bf0391be-e6af-4749-9396-4a344af3e416 (1st sol)
For experiment's sake, I tried GPT for this problem multiple times
1st try: https://chatgpt.com/share/b3b010b9-88ec-43b5-b52d-864a9c0c0d6e most sol were almost same as mine (2nd sol — 99% same except break, last sol — 100% same)
2nd try: https://chatgpt.com/share/751806fe-6eba-443d-bf51-86418ee338c1 : total 15 sol, 11th sol — 100% same, 5 other sol — mostly same.
As using GPT is allowed, my sol should not be skipped. Even without GPT, most people might have exactly same sol give the steps for this sol were trivial — do preSum -> two pointer (except initial value of variable, my main part of my sol match with author)

I received an email regarding my solution 276222389 for the problem 2000C significantly coincides with someone solutions. I was using ideone.com for my few last contests, I did not know that someone else could see my code from there, I am really sorry for this mistake. I will take care of this, please don't give me any penalties or block my account, I was unaware of this.
Please remove the skip on my contest.
I received a message saying "Your solution 276677150 for the problem 2004E significantly coincides with..."
I haven't copied the solution from anywhere. Here is the link to the resource published before the contest here
I hope my solutions won't be skipped. Thank you for the consideration.
I received an email regarding my solution 276289035 for the problem 2000C significantly coincides with someone's solutions.

Attention!
Your solution 276649102 for the problem 2004E significantly coincides with solutions Penguinia/276649102, cccsolver/276654468. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
I believe that this is a coincidence. In my solution, I first calculated the grundy numbers of nim based on the prime numbers. This is like an edited version of the Sieve's algorithm in https://www.geeksforgeeks.org/sieve-of-eratosthenes/. Additionally, I got the idea of using the xor of grundy numbers from https://codeforces.net/blog/entry/66040. Both of these are published before the start of the contest. Thus, I believe that it only got skipped because I used some variable names that were similar to another person's. Variables like a, and dp are commonly used.
Dear MikeMirzayanov I kindly request you to look into this matter and remove the skip on my contest.
But the codes look like even this part is copied...
276649102, 276654468
First, my first code submission 276639502 was based on the grundy numbers and mex, and the code is very standard and can be seen everywhere online like Geeksforgeeks (https://www.geeksforgeeks.org/combinatorial-game-theory-set-4-sprague-grundy-theorem/) and USACO Guide (https://usaco.guide/adv/game-theory?lang=cpp).
In addition, as that code's time limited exceeded the required time limit, the idea of using Sieve of Eratosthenes to optimize came to mind after trying to use a map mp to store the function f's value. The version that I edited was from Geeksforgeeks (https://www.geeksforgeeks.org/sieve-of-eratosthenes/).
I do acknowledge that a lot of parts are extremely similar, but as you see, my first code submission was way before Penguinia's final submission and probably also his first submission to the problem. I do not think that this was copied by anyone as I remained most parts of my first submission code and only changed the function.
Last, I find that other users except us have a similar code submission like 276599244 and 276603899 and many others. I truly believe that this is a coincidence as other people have also come up with the same solution and nearly the same implementation (with only variable name and coding habit differences).
I am sorry that this accident has happened, but please kindly reconsider your decision. Thank you, MikeMirzayanov.
how da hell it conincide what???? i wrote the whole thing
there is no possible way it is coinciding since i wrote the whole code alone for the E solution what is going on only for this particular solution how?
same thing
I only used repl and gpt..
I think i have used ideone in public mode by mistake because i dont have idea that someone can see my solution there thats why my solution has been copied by somebody.
I also received an email regarding my solution 276603069 for the problem 2004B significantly coincides with someone solutions. I was using ideone.com for my few last contests, I did not know that someone else could see my code from there, I am really sorry for this mistake. I will take care of this, please don't give me any penalties or block my account, I was unaware of this.
I used ideone in public mode by mistake because i didnt have any idea that someone can see my solution there. Thats why my solution has been copied by somebody. I dont even know that person please give my rating back cause i worked hard for it and it means a lot, you can see my previous submissions. I did not know about this rule it was my first time making this mistake please forgive me and i wont use ideone or any other public access ever again and this mistake will not happen again. I usually code in Sublime but on that day it was having issues it was showing the Buy Sublime box, so I used ideone and I didnt know that my code was publically accessable. Please forgive me this one time and please dont give me penalty or block my account. I apologize for my mistake MikeMirzayanov.
Sorry but it was a coincidence I used the online compiler of what so called ideone.com and that is why this issue happened , actually what happened is I think i have used ideone in public mode by mistake because i did'nt have an idea if anyone could checkout on my solution on https://ideone.com/ and i guess that could be one of the reasons that my code for the same problem was seen on other participants submitting for the contest . And being a newbie on codeforces it was hardly my 5th or 6th contest . I apologise for the mistake and would seek my ratings back given that i wont perform a mistake like this in future . looking for a positive reply . Thank You .
I wanted to get my rating back but instead my graph got all messed up all of my contest in my graph are showing in the right corner. Please fix it you can cancel my rating for last 2 contest as you did earlier and make my max.newbie rating as 934(2 contest ago) instead 991, I will get my rating back fairly but dont do this to my graph(all the contest are cluttered in right side). I will not do this mistake again as i promised earlier. This is my only CF account and i want to show my hard work and hours in my resume once i reach a certain good ranking fairly but if all my contest show like this it will all go to waste. Sorry for my mistake and promise this wont happen ever again. Please make my graph show my contest like earlier(like normally graph shows) MikeMirzayanov.
Dear Codeforces Team,
I apologise for the delay in raising this. I was not sure how to raise this issue, and gave the upcoming contests as well.
I received this message, and was shocked to see this which made me very sad since the past week.
My solution 275824273 for the problem 2002D1 (and 275824704 for the problem 2002D2 — both are same) significantly coincides with solutions Way.To.Cp.01/275792092, virat_2519/275800454..
I carefully checked my code and his and found that our code was a little similar, but I have no idea how/why.
The approach I used was the one in the tutorial — if any child node v has a position interval [pos_v, pos_v + size_v — 1] that does not fall within the interval [pos_u, pos_u + size_u — 1] of its parent u, it is inconsistent — we can maintain this by keeping track of the number of u which violates this condition. We can check for each u using sets, and finally check after each swap operation — this approach I used might have been used by others too.
In my submission, I have clearly mentioned the name of variables, such as inconsistencies, subtreeSize, myinser, delete (lambda fuctions), and also mentioned the logic in comment due to my habit of commenting. I also have all other helper code I use, which not at all matches with their code — but they have common template code which is not even used, and it is not in my submission — the name of variables, and control flow is also different (like calculate function).
(I also had autocomplete and Github copilot installed but they did not give any code, and I deeply apologise if it violates the regulations — I don’t use them and would disable them for future. However, I used the online ide ideone.com.)
I don’t know any of these people, and I think this is a system mistake which happened with me — you could check all 3 of my other solutions within the same contest or previous ones, none of them would relate to any of their submissions (and they might have done such things earlier, there is no consistent way in their code which is not the case with me). I think my in-contest behaviour proves my innocence and I'm willing to swear on my character that I wrote this code myself.
To be honest, I was very shocked when I received this email, because I don't know even slightly what happened — I don't know where the default option (Public access to your code) is set in ideone.com, but I will learn how to set it now to prevent my code from leaking again.
The rating of codeforces is very important to me, and I have been consistently taking part in contests honestly since past 3 years — this never ever happened earlier in so many contests and I assure this won’t happen again. I really hope and request you to consider that my punishment is reduced.
I am willing to prove my innocence in any way possible. I will be highly grateful for your consideration.
Thank you very much!
I am writing to sincerely apologize for an oversight on my part during the Educational Codeforces Round 169 (Rated for Div2). I mistakenly submitted solutions for problems A and B from both of my accounts.
To clarify, the two accounts are mine only
Codeforces handle: unhdgfksb, email: [email protected] Codeforces handle: b23cs1034, email: [email protected] I was unaware that making submissions from both accounts would be considered a violation of the rules. I assure you that there was no intention of rule-breaking, and I did not copy code from any source.
I deeply regret this mistake and will be more vigilant about following the rules in the future. I kindly request that you consider this apology and allow me to continue participating in Codeforces contests. I appreciate your understanding and assure you that I will adhere strictly to the rules going forward.
my verdict on my orignal solutions have been showing skipped and my rating for last 2 contest have been reseted. I wrote very production level codes with standard naming of functions and variables which may lead to matching my solution to many users. i will avoid naming functions standardly but please look into the matter and give me a verdict on my codes.

I have received a message that my solution matches someone else's solution.
I honestly have no idea how this could have happened. It's frustrating because if I wanted to cheat I had to open someone's profile randomly and saying: "Hey man, here is the solution for this problem for this contests hopefully you are participating right now, and It helps". It's funny because I wouldn't even know where to start if I wanted to. The only time I ever run my code on an external site is on "https://www.programiz.com/cpp-programming/online-compiler/" to check if my output matches the expected result. I was under the impression that this site was secure and wouldn’t leak or share my code. I’m genuinely at a loss here and don't know what to do next. This whole situation just feels absurd.
Now I think I face two challenges at the contests: 1- Solve the problems 2- Solve the problems in a way that[submission:277378639] doesn't match someone else's solution (hopefully)
you were skipped before. put the warning message
Yes, the same thing happened to me last time. I thought maybe I made a mistake when translating the solution from Python to C++ using ChatGPT since the problem wasn’t very Python-friendly. My initial Python solution got a TLE, even though the time complexity seemed reasonable, so I decided to use ChatGPT to help convert it to C++. I figured GPT might have generated similar code for others in that case, but this time, I’m completely baffled. I have no idea what's going on.
also here is the warning message:
Attention!
Your solution 277378639 for the problem 2001D significantly coincides with solutions shiva7217/277372305, rafi_zahedi/277378639, shilpabanerjee50/277382619, anshgoel2580/277391201, lijaweny/277391734, wlu28/277395335, VigneshDatta/277412877, raj_akriti6022/277412990, ashishjha_2004/277413099, superni/277417115, Pranavi_999/277417700. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
while part is identical in all submissions listed or at least most of them ?
Looking at the debugging points of my code you can see that this is legit my code. At this point, I have no way to prove I didn’t cheat or give away my solution. Maybe you’re right—maybe I’m some kind of mastermind cheater without even realizing it. I grew up an immigrant and respected the rules of every country I've been in, and that is what I will be doing right now, just respect to you and respect to rules of this website.
what about the same ordering in the while ? coincidence ?
Looking at the submissions, I’m honestly blown away by how identical they are—it’s like a perfect copy-paste, even though I have no idea how this happened. As I said before, I respect the rules, so just do what you need to do.
Actually, what happened was that I firstly submitted my 2001C [contest:https://codeforces.net/contest/2001] solution
I don't know how it matches(only the starting part), but I Use stack in the question, and others do not. frankly after writing my code, I pasted It to ChatGPT to see any error in that code(but it gave me same code that I wrote before along with some formatting and changing some variables names and adding comments), So after pasting I got the code that has variables similar to those in the matched ones but the whole thing is not same only starting part(5 lines). I don't why the system skips my questions although my solution does not match entirely with others whom the system is claiming it is the same. I want to complain about this after a long time I became a pupil and due to this nonsense activity by the system I again landed up to newbie.
I recently participated in a Codeforces round (Div 2), which was my 43rd round, with a rating of 1199. I solved three questions, but today I received a notice that my code for the third problem matched that of other participants. I was shocked because I didn't use any external platforms like ideone.com. I believe that code logic can naturally match among participants, but I did not violate any rules.
Additionally, I had previously submitted a solution for the same problem that resulted in a wrong answer, and it contained a similar logic. This submission demonstrates that I was independently working through the problem and refining my approach. How can I prove my innocence? After recently achieving the Pupil rank for the first time, it's particularly disheartening to face a potential rating decrease due to this issue. I’ve been working hard to improve, and this situation is really demotivating for me
I have been practicing using resources such as the Love Babbar and Striver coding sheets available on YouTube. My solution was independently implemented based on the knowledge I gained from these practice sessions. I am attaching my code file here for your review.
I am a student at IIT BHU, and like many of my peers, I use the college's Wi-Fi network to participate in online competitive programming contests. Due to the high number of students using the network simultaneously, there may have been some misunderstandings regarding our activities.
I want to assure you that I am fully committed to the principles of academic integrity and fair competition. I do not engage in any form of cheating or unethical behavior during these contests. My participation is purely based on my own knowledge and efforts.
Sorry it was coincidence.. I used Ideone. I learned about this site from my college friend.i did not knew it was default by public. It will never happen again.
Sorry. It was a coincidence. I usually use ideone for my college coding. I learned about it from my friend.I used it on this contest..i didnt know problem D will ne leaked__.i did not know that it was publicly accessable..it won't happen again..
I'm sorry for the confusion caused. It was purely coincidental that I used the online compiler on ideone.com, which led to this issue. I believe I might have accidentally used ideone in public mode without realizing that anyone could view my solution. As a result, my code for the same problem might have been visible to other participants in the contest. I sincerely apologize for this mistake and request that my ratings be restored, with a promise that I will be more careful in the future to avoid such incidents. I hope for a positive response. Thank you for your understanding.
Sorry But I used ideone in default mode that why the problem occurs plz dont blocked me ..I apologize for my mistake.
Sorry but it was a coincidence. I was using ideone.com and wasn't aware that it is in public mode. Will never repeat this mistake. Sorry for that.
hi__
Dear Codeforces Team,
I hope this message finds you well. I recently participated in the Codeforces Round 968 (Div. 2) and unfortunately got skipped in the standings due to a similarity issue with the solution I submitted 278085453 for the problem 2003C . I believe this may be because I used a solution generated by ChatGPT, which might have led to multiple participants submitting identical or very similar solutions.
I understand the importance of maintaining the integrity of the competition and avoiding plagiarism. However, I would appreciate it if you could review my case and provide any feedback on how I can avoid such issues in the future. I am committed to participating fairly and would like to ensure that my submissions are in compliance with Codeforces' guidelines.
Thank you for your time and consideration.
Sorry but it was a coincidence. I was using ideone.com and wasn't aware that it is in public mode. Will not repeat this.
MikeMirzayanov I'm sorry, it was purely coincidental. This is happening for the first time with me. I myself am confused about how this happened. It's surprising that a solution could be the same for many people. I did not cheat in any way, and it may be because we used a similar approach. I will be more cautious in future contests to avoid such situations. Please understand that I have worked incredibly hard to reach this level. Taking away my rating or blocking my account would greatly impact my efforts.
i am sorry .i didnot know anything .i and my friend was solving the last problem.but all problem solved by me please check i didnot do anything .please forgive me and i never do this again .and sorry i was using ideone for educational purposes .i will take care of it from upcoming contets.
I have received a mail regarding 3rd problem of Div 2(Round 968)2000C - Numeric String Template. That my submission 278093855 is similar to some other submissions. This question was very intuitive. To print the distict characters as far as possible to each other traversing a map and emptying it accordingly is a very basic approach.
At first I wrote the following code
This went into infinite loop in my ide.
So I searched for another way to traverse a map and a stackoverflow post came in front of meStackoverflow link. And after seeing this I only wrote the submission I provided above.
You can also check the following lines were present in the submission link I provided at the starting of this comment.
Please look into the matter as it was completely my own intuition and written code. I have not done any violations in this contest.
It was just a coincidence like yu can see my previous two solutions . It just a coincidence with procedural stack and priority queue implementation ****
my solution for the question 2003C was flagged, but i cant understand why. i have written the code completely on my own. i have sent a solution to just my friend. he might have uploaded it online. i kindly request you to give my ratings back[contest:https://codeforces.net/contest/2003/problem/C] https://www.imghippo.com/i/VjUmK1724782881.jpg. this is the screenshot of the code i have sent him. please look into this
I'm new to codeforces and I was using a public ide for testing my code ,if this could have caused this penalty then i'll make sure to not use it again .I don't have any intention to get my ratings up just for the sake of it ,I am here to practice and I am a beginner. please consider this statement.
I recently received a notification that my solution (submission ID: 279216653) for the problem 2008G in Codeforces Round 970 significantly coincides with several other submissions. I would like to state that I have not copied anyone's code, nor have I intentionally shared my solution. I believe this could be a coincidence, as I used Ideone for code compilation during the contest, and I was unaware that my code might have been publicly accessible by default.
I sincerely apologize for any misunderstanding and will ensure that I avoid using public platforms like Ideone for future submissions. Please consider my case and I kindly request that my ratings are not affected, as I did not violate the rules intentionally.
Hello, I have been wrongly accused of plagiarism in Codeforces Round #970 for the problem 2008E, and I would like to address the claims made against me. I was not aware of Ideone, as mentioned in the email. For competitive programming, I solely use VSCode, and I do not share my code or use any online collaborative tools.
To further clarify my position, I have reviewed the submission IDs mentioned in the accusation and compared them with my own. There is no similarity in the structure of the code. Here are the submission IDs that were referenced in the accusation:
My submission ID: 279222153
Other submission IDs: - 279128926, - 279181717, - 279203378
Additionally, you are welcome to review any other submissions specified in the mail to confirm that there is no plagiarism from my end.
I kindly request a reevaluation of this case, as I believe this accusation is a misunderstanding.
Thank you for your consideration.
@MikeMirzayanov My submission 279198595 is detected to be matched with 279100633. I would like to clarify that it is a mere coincidence. I do not know the person, neither I have copied the code from any website etc. The strategy used in my code is based on cycle detection in a permutation and counting properties within those cycles (in this case, the number of black nodes). It has some well defined steps that are Cycle Decomposition, Cycle Traversal, Counting Properties within the Cycle (here, the number of black nodes). Both the solutions use the same strategy, but for sure I have not copied it from anywhere, and I do not use any public ide for contests, so, the other case is also ruled out. Please, don't take actions like blocking my account.
279117059
Thank you for notifying me about this situation. I would like to clarify that my solution for problem 2008D was developed independently. I used a standard BFS approach with some modifications. I had practiced BFS and similar graph traversal techniques before the contest, and I have solved similar problems on other platforms such as GeeksforGeeks. In fact, I had written a similar code when working on a task from GeeksforGeeks task.
The taks was on https://www.geeksforgeeks.org/breadth-first-search-or-bfs-for-a-graph/, I copied the solution on this site and I modified it.
I used the same variable names as on the site, I think that can't be a evidence because I usually do it.Also for me the comfortable is iteration from 0,that's why i did it.If we come to the modified BFS, I copied it on geeksforgeeks that was published before contest.But the task has same method I modified it and Codeforces was asking to black colours from i position
I understand that the message mentioned a possible rating adjustment, and I hope this explanation provides clarity. If needed, I can provide code from my previous practice sessions to verify my approach.
Thank you for your time and consideration.
I was writing code on Ideone and wasn't aware it was set to public mode. I apologize for the mistake and assure you it won't happen again.I was unaware of this issue. I'm sorry and will make sure not to repeat this error. Forgive me this time and please don't decrease my ratings. :(
I deeply regret the oversight that occurred when I was writing code on Ideone and unintentionally left it in public mode. I sincerely apologize to Codeforces for this mistake. But I assure you that I have learned from it and will be more diligent in the future. I am truly sorry for any inconvenience this may have caused and understand the importance of adhering to the platform's guidelines. Please accept my heartfelt apologies, and I promise to be more cautious to prevent such issues from happening again. Thank you for your understanding. Please forgive me for this and don't decrease my rating. I am very sorry.
Please see here:
Primarily pupil + newbie make mistake of "using ideone."
It is seems on purpose. *Why only low rating? I've read blogs to gain more clarity and research. Cheaters can solve: ABCDE in Div2. Therefore: cheters are not low rated: clearly they are at least expert or higher. Hence pupil + newbies are not using ideone to cheat. They are just trolling with necropositng.
Why only pupil + newbie? It is cleaer: they are attention seekers. Respect is gained at the specialist level. So lower rated feels unwanted in the community.
Solution: let us bannish all users not over 2500. I think this is a needed change to improve community. Do we feel pity on them. Then we can make a seperate fighting rink for all newbies and pupils. They will advance before competigin in elite level, with the remaining community.
Upvote please iff agree
I usually write my code in vscode but on the day of cd round 970 (div3) by bitsstdc++.h file got corrupted and stopped working ,so had to go to ideone and in hurry was in public mode and did not noticed it. I apologise for it and will make sure such things do not occur in the future .I beg you to be linient with me as i am still a beginner and dont block me or give any penalty
Your solution 279145863 for the problem 2008D significantly coincides with solutions T.D./279097131, nr_ulan/279117059, ptripat408/279118766, anandraj_02/279138205, taharukaiya/279145863.

I just wanted to clear things up. I honestly don’t know the others, and I have no clue how they ended up with solutions similar to mine. I solved that problem completely on my own. It was my first time using ideone.com, and I didn’t realize that its default settings let others see my code. I’ve learned my lesson and will definitely be more careful from now on. I’d really appreciate it if you could give me back my ratings.
I received a message from the system saying that my solution to the problem F in the last div 3 is similar to another account's solution to this problem and my solutions were blocked. This account has nothing to do with me and there are some leaks on social media sites that occur during the contest and he may have brought his solution from these sites, which led to his method being very similar to mine in solving the problem and if I cheated from him then all my solutions must be similar to his and this problem must be looked into
I mistakenly used Ideone in public mode without realizing that my solution would be visible to others. Unfortunately, someone copied my work as a result. I genuinely apologize for this oversight and assure you that it won't happen again.
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occured.i wasn't aware it was in public mode.
Same here to me!
Sorry but it was a coincidence .. I published my code on ideone.com that's why the problem has occurred. This will not happen again
I received a mail just now regarding the solution for problem 2014D significantly coincides with many other solutions! MikeMirzayanov Sir and Admins please look carefully as my code has been constructed completely in a different manner! Few part might be similar but I would like to put this clear Sir that neither I used any online complier nor I used GPT to search the solution for the problem, please recheck once so that you can also understand my point! I always adhere to codeforces rules while participating in the contest!

Yes, it was my first time at ideone as one of my friends suggested to use online ids to check for test cases before actual submission. It was my first expereince with ideone. And now I realized that I used it in public mode which led to all the mess. I promise that I will be a lot more strict and aware of such facts and keep my code safe. Thank You codeforces team for letting me know about this.

While I understand the rise in my account may be suspicious, I will be glad to link proof to my results in regional/national-level competitions to prove my competency. Thank you.
Dear Codeforces Team,
I recently participated in the last div3 contest, and I received a notification regarding a significant match between my solution for problem 2014D and multiple other submissions. I want to assure you that the similarity between my solution and others was purely coincidental and completely unintentional.
I did not share my code with anyone during the contest, nor did I collaborate with others. I typically write my code independently, and the structure or logic I followed in this problem must have coincidentally matched that of others. I realize that certain problems can have straightforward approaches, which could lead to unintentional similarities among participants. I did not use any public platforms like ideone.com or other sites where my code might have been visible during the contest. I believe this coincidence occurred due to the nature of the problem, where many participants might have come up with similar logical structures or code patterns to solve it. If you need further information or details, I am happy to provide them. I kindly request you to reconsider the penalty and restore my rating. I deeply value fair competition and would never intentionally violate the platform’s rules.
Thank you for your understanding and consideration.
Sorry. KopInfoTech is my roommate, he doesn't know anything about the rules and so do I, that's why he copied my code. Please kindly return my ratings back. For verification you can ask him, he is ready to confess about the incident.
Dear codeforces.
This Has been sent 4 days ago and i have just read it. Your solution 282347751 for the problem 2014D significantly coincides with solutions callmeanupam/282263344, VIRTUOSO_4/282347751.
I wrote my code using my problem skills, and my code isn't even coincides that much. As you know there're a lot of users enters the contest so that there may be some similar codes.
So please revise this coincidence and return back my rating.
Thank you for your patience.
It was a complete coincidence, and I don’t know how my code ended up being the same. i thought it was because of ideone but its not. My code is actually different.
Hello Mike! The following is the email I received for Round 975 Division 2 contest.
Attention!
Your solution 283244799 for the problem 2019C significantly coincides with solutions sreenishsharma83/283242111, Manasvith/283244799. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
sreenishsharma83 discussed the approach with me during the contest, since he got the idea of how to approach it first. I merely implemented his idea. You could check the submission times, he was the first and I submitted it later. I also got another mail referring to my submission to 2019B coinciding with almost a 200+ submissions, which I think is a mistake because my approach was supposedly the simplest way to approach the problem. So, If there's supposed to be impose penalty on anyone, that should be rather than sreenishsharma83. For 2019C, I agree that he was the who told the logic only, but not the entire code.
lalithcs/283247475 is my code and i definitely did not copy. i don't know how it coincided with others code. Please remove that. My approaches were the most easy ones to be approached and they can easily be using the variables because there are some general conventions. Please remove this ban
It appears to be a coincidence that both codes a similar approach but differ in implementation. chayon017/283231213 is my unique approach and implementation .You recheck the both code reham127/283199195, chayon017/283231213.

Dear Codeforces Team,
I hope this message finds you well. I recently received a notification regarding a potential rules violation due to similarities between my solution and others. I would like to clarify that any resemblance was entirely unintentional.
Upon reviewing my process, I believe the issue may have been caused by the accidental use of public settings while working in an online IDE, or by referencing a common resource prior to the contest. I have now ensured that all my coding environments are private and will take extra care in the future to avoid any unintentional leakage.
I take the integrity of competitive programming very seriously and would never knowingly violate the rules. I sincerely apologize for this mistake, and I have taken steps to prevent any such issues from occurring again.
If you require further information, please feel free to reach out, and I will be happy to provide any clarifications. Thank you for your understanding and for the opportunity to address this matter.

Befor i used ideone now i changed.please check my IDE i used my sublime for my coding from last 2 days sir,(https://drive.google.com/file/d/1JmcTdfP7umX8NGr-b_mJ8_vLXjd-_l_Q/view?usp=drive_link)
I genuinely wrote my solution for Problem B in Codeforces Round 975 on my own. I have participated in many contests to date and consistently wrote my own solutions. I kindly request you to review this submission, as well as my previous contest submissions. Any similarity with other solutions is purely coincidental.
Dear Codeforces Team,
Iam 200% sure that iam not copied my code from anyone sir. my approaches are completely unique and i don't know how this happens sir.please review my solutions once sir
Hey, I wanted to clarify that my submission(ahad169/283224731) for Problem 2019B was created independently. While I see some similarities in logic with another submission, I approached the problem using my own methods and styles. My code has distinct differences in structure and variable usage.
I appreciate the effort to maintain fairness in the competition, but I assure you I did not copy from anyone else. Thank you for your understanding!
Best regards, Abdullah Al Ahad Bhuiyan
Respected CodeForces Team, I found that I have recieved a mail that my solution for problem 2019B coincides with others and my account might be blocked. I usually code on vs code but since my laptop was having some issues, I used another laptop and coded on an online platform. I really don't know how I recieved this plag since I have coded the solution on my own only. Please dont't reduce my rating or block my account since it will affect my profile.
Subject: Response to Code Similarity Allegation — Solution 283224045
Dear Codeforces Team,
I hope you are doing well. I am writing to address the message I received regarding the alleged similarity between my submission (ID: 283224045) and other users' submissions for problem 2019B. I would like to clarify that my solution is entirely my own work, written independently using an online compiler.
I did not reference or share my code with anyone. I used the online compiler only for writing and testing my code. I did not make the code publicly accessible in any way during the process. I understand that platforms like these can sometimes leave traces or allow for accidental public access, but I ensured that my environment was private throughout my work. I used OneCompiler
I take this accusation very seriously and am committed to ensuring that my participation on the platform remains honest and within the rules. If there are any additional steps I can take or further evidence I can provide to resolve this issue, please let me know.
Thank you for your attention to this matter, and I look forward to your response. I have been wrongly accused before also in Codeforces Round 974 (Div. 3), I humbly request to please rollback all my ratings I promise that from now on, I'll not use any sort of online compiler and just use my local machine.
Best regards,

I like how you change for loops into while loops xD. Let me add something, your recent 976 will be skipped too like 2 wrong answers on A and solving after 30 min. Then, wow D+E in 20 minutes :--D
They all are genuine code by me, I did solve D and E in 20 minutes while I took a little more time for A, there can be multiple reasons for it like my state of mind etc. I request you to consider my contests
From next time I'll make sure my codes and approaches are very different than the conventional.
Best Regards [sahibnanda]
I think your 976 D and E are cheated too.
Your E submission, I found similar among many cheaters, a blog is to come :D
Best Regards [Golden Ratio] [Reincarnating [Heap_OverFlow]]
I like the fact that this aged well, lmao. I don't know why he is still trying to defend it when it's obvious. Other than the fact that he solved in D+E in 20 minutes, just looking at the codes at first glance makes it clear that he fabricated the code using AI, which is also prohibited, so he's cheating either way.
i didn't knew this was the case so it was unexpected for me and i am really sorry for mistakes but this was unintentional so don't penalise me for this.
skill issue
I think my ideone was in public mode so that's why it happened.
I think my solution may be similar to other because of same approach
Dear codeforces admins, Please return my rating, I didn't cheat or use ideone or anything. I use vim on my local pc. It's a false flag.
Your solution 282335017 for the problem 2014D significantly coincides with solutions Ar7e9/282335017, BFR/282368362. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
The solutions aren't even similar lmao.
Thanks.
Your solution 284577317 for the problem 2021C1 significantly coincides with solutions rakeshpatel17/284577317, vinayak_20/284585162. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code).

In case of repeated violations, your account may be blocked.
I assure you that the similarity in my solution for problem 2021C1 is purely a coincidence. I did not intend to violate any rules. I used IntelliJ IDEA for my coding, not the Ideone compiler, and uploaded my solution as a file.
Hi Codeforces, I recently participated in Codeforces Round 977 (Div. 2, based on COMPFEST 16 — Final Round). In this contest int the question C1, my solution coincided with the solution of rakeshpatel17. I assure you that I didn't used ideone and i wrote my code in my VS Code.
Now the possible reasons for the similarities of the code could be because of certain points :- 1. It was a very easy question with the same approach. 2. I have made 2 arrays and named it a and b which I usually do so as to name it very short 3. Now since the code was very short, it has very high probability of coinciding with someone else's code. 4. My naming conventions has always been same. My other solutions have same naming conventions and code style. 5. The code just used 2 arrays and a Hashset and the conditions under the loop was very easy and most people wold write the same.
Therefore I urge Codeforces to remove the violations which I haven't done and return my ratings back.
Hoping for the best and fast resolution of this problem. Thank you.
This was the message which I received -

Hello Codeforces team, i received this message recently. Attention! Your solution 284575789 for the problem 2021C1 significantly coincides with solutions secret_naitik/284556121. Iam not copied my code from anywhere it comletely coincidence naming conventions of variables are different from one another.That is the easy question. The logic might be same for them also.i used my sublime for this code and i not used any ideone also.Check my previous solutions also..I don't know why this message came..please consider this and resolve this issue as soon as possible..Please dont decrease my ratings these are all my own hardwork.
Thank You Codeforces team.

Though i was not penalized and my ratings were not taken back, i wanted to bring to your attention that this is purely coincidental, if you will look at my previous submissions in the same contest or other previous contests my coding style matches with the current submission and it was a very small code so there are high chances of coincidences. Also i didn't use ideone, i use sublime for coding.
Report, someone is here https://codeforces.net/contest/2021 During the competition (virtual participation after the game), I plagiarized my code, here are the results.
his' Submit Records
my Submit Records
And his submission time is later than mine.
hey! i am new i don't know what happened but i have mistakenly submitted the code in my institute mail id account but later i figured out that this was on wrong account so i uploaded in my original account. If you have any doubt whether both account belongs to me or not i have valid proofs. Please let me know if required or else you can search both account on google and you will find out same name is associated to both email id difference is that one is personal email id and other is institute. Please let me know i will provide you with all proofs and details.
kunaly6 and ultimate112 both are my id and i didn't know that this will happen with me. Next time i won't submit the solutions in both the ids and will be aware of rules and guidlines. I got this mssg for this " Educational Codeforces Round 170 (Rated for Div. 2) " . If u need valid proofs then please let me know.
it was a coincidence .. I have written my code in online compiler that's why the problem has occured.

I assure you that the similarity in my solution for problem 2025C is purely coincidental. It was a typical sliding window problem and most of the people follow the standard template for this. I used my local VSCode editor for my solutions, not any Ideone compiler, and uploaded it directly to this platform.
Thanks Codeforces :)
This is really undescribable that, same code as of mine can be written by someone. I apology, if that happen, but I didn't mean it. May be I mistakenly shared it with my colleague. pls apology me and my colleague, as we both are newbie
I did not know that ideone.com makes the code public for other users. Thanks for informing. I will not use not again. You saved me a million dollars.
Thanks and regards

Hello, I have received a notice about my solution for Problem 2030A. I assure you that I wrote the code independently and did not share or copy solutions. I believe the similarities might be due to the nature of the problem, as there are common approaches to solving it. I don't know how but our code matches exactly including the function name and variables. It might be due to using the same online website for reference to the problem. I assure you that I wrote the code independently and did not share or copy the solution. Please don't change my rating and please let me know if you need any further clarification from my side.
I have received a notice concerning my solution for problem 2030A, and I want to clarify that the code I submitted was written entirely by me.Kindly don't decrease my rating.If you need further clarification you can ask me.
Hello,
I’m writing regarding my submission (https://codeforces.net/contest/2024/submission/286985039). I have already solved similar problems on other platforms, and this type of problem involves a basic, commonly-used approach. If my solution resembles others, it’s likely because we’ve used the same foundational logic that’s natural for this problem type. I am dedicated to solving problems daily on CodeForces, with a 221-day streak. This has greatly enhanced my understanding, and I request that you please review my case in light of these efforts.
Thank you for considering my request.
Edit — I use VScode to write my code and sometimes compile them on onecompiler.com . I do not think this will be an issue! I already got the 2 wrong answers in this problem , first I was trying to solve it by using the concept of minimum element of pairs , then I tried to arrange all the pairs by using there sum , arranging them as per their sum in ascending order and it got accepted and now what could I have done?? Please do not skip my solutions , You can also see the timing of A and B how fast I cracked them it was my best div2 till date. Thanks again!
Thanks again!
Subject: Clarification Regarding Plagiarism Allegation in Contest 2033, Problem 2033F
I am writing to clarify the circumstances regarding my solution submission (ID: 287729587) for Contest 2033, Problem 2033F, which has been flagged due to similarities with several other solutions. I would like to emphasize that I independently developed my approach to the problem, but I did make use of certain common programming tools and libraries widely adopted by competitive programmers.
In competitive programming, shared tools, templates, and approaches for precomputing values and structuring code are common, especially when facing specific constraints that naturally direct solutions toward similar patterns. For instance, techniques like optimized precomputation and code modularity are standard practices that can result in syntactic similarities. These practices, along with template usage, are designed to streamline the implementation process, allowing me to focus on problem-solving rather than the repetitive setup of boilerplate code.
The solution structure and logic reflect my personal approach; however, the similarities noted can be attributed to the tools and libraries that assist in the setup and structuring of competitive programming solutions. My intent in using these resources was purely to aid in implementation, not to replicate or derive my solution from others.
I hope this explanation provides clarity on my independent work for Contest 2033, Problem 2033F, and addresses any concerns regarding this similarity.
I have done a mistake i have not used a public class please give my rattings back;
My solution for the problem 2024C has been found similar with one guy who i dont even know, I have written the whole code myself .I had used my own logic where I have sorted the array on basis sum of pair elements. this same logic might have been used by other person where i have used comparator in sort function . Kindly check this and remove the plag.
for the problem 2024C, just the code logic is of one code snippet which is sort(arr.begin(), arr.end(), [](pair<ll, ll>& a, pair<ll, ll>& b) { if (min(a.second, a.first) == min(b.second, b.first)) { return max(a.second, a.first) < max(b.second, b.first); } return min(a.second, a.first) < min(b.second, b.first); }); and which was general way of sorting an array with comparator function which resulted in plag with other guy please further look into this code
same case here i used ideone and this happen for the first time i'll take care about it in future please give back my ratings . I had no idea about it . I am sorry for it .
Your solution 287709551 for the problem 2033D significantly coincides with solutions rishabhluv/287709551 287709551, Arin_Sahu/287754861 287754861. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
I want to clarify that any similarity in the solutions was purely coincidental. This problem was relatively straightforward, with only a few lines of code needed to solve it, which naturally increases the chances of coincidental similarities. Additionally, I was participating as an unrated user in this contest, so I had no reason to engage in any form of unfair behavior. I assure you that I approached the problem independently and followed the contest rules.
sir,I received a notice regarding solution 287771721 for problem 2033B, which was flagged as significantly coinciding with another solution. I am a beginner and wasn’t aware that using platforms like Ideone.com in public mode could lead to unintended code exposure. I now understand that using Ideone's default public settings can cause unintentional code leakage, and I will be careful to avoid this in the future.
I assure you that I didn’t intend to share or leak my code, and I’ll take extra precautions by not using Ideone in public settings or by switching to a private environment entirely. Thank you for your understanding, and I apologize for any issues caused by this oversight.
Hello Codeforces Team,
I recently received a message regarding a similarity between my solution (ID: 286971111) and another user’s solution (Mradul2004, ID: 286933028) for problem 2024C. I want to clarify that I did not engage in any form of cheating, nor do I know the other person.Here’s my code:
Given the simplicity of the code and logic for this problem, I believe there’s a high chance of similar approaches being used by different participants.
I independently developed this solution and did not share it with anyone. Please let me know if there is anything further I can provide to clarify this matter(I have not used any publicly available code).
Thank you,
The same happened with me i was writing the code in ideone and i wasn't aware it was in public mode. I apologize for my mistake and will never do again.
i do write in ideone but some times in hurry it is easy to change setting while logging in it so many people may forget to change their settings same happened to me
same thing i didnt copied code just used online complier for executing the code nothing else i will not use any code editor further please do not mark me as cheater and dont decrease my ratings
Hello Codeforces, Just today I got a message that my solution 288149902 coincides with the solutions of other users. Actually I am a college student and I gave the contest from my college's computer lab because of some issues with my laptop. I used ideone to code without knowing about its public default settings. It was unintentional and I apologise for my mistake and will make sure that it doesn't happen in future.
Hello there, I got a message regarding matching someone's codes with me. I'm claiming that I didn't take the help of any other person. Also, seeing the codes are skipped. Please resolve that. Although, I used onlinegdb.com to compile the 288167980 code.
Please retrieve my code's status to the previous one.
Hello Codeforces Team,
I recently got a message saying that my submission for 2026B and 2026C have been flagged. I deny that. the program I wrote looks very commonplace. It might have similarities with other programs, but I confirm that it is original.
Thank you
Subject: Clarification on Solution Similarity for Problem 2026B in Educational Codeforces Round 171
Dear Codeforces Team,
I recently received a notice regarding significant similarity in my solution (ID: 288561544) for problem 2026B, which may suggest a violation of rules. I would like to clarify that this is purely coincidental, as my solution is based on standard algorithmic techniques commonly applied to problems of this nature.
In particular, my approach combines binary search and dynamic programming (DP) concepts. Binary search is used to efficiently determine the minimum possible maximum distance by narrowing down the search space, a well-known technique for optimization problems. The DP approach was implemented to track reachable positions based on constraints, making use of two arrays (noExtra and oneExtra) to manage possible moves with and without an extra cell.
I did not reference or share code from any external source, nor did I use public coding platforms like Ideone with default (public) access. This approach reflects a standard method for tackling similar problems and was devised independently.
Thank you for reviewing this clarification.
Dear Codeforces Team,
I recently received a message regarding a similarity between my solution 288544883 and asd7766zxc's solution 288588555 for problem 2026E.
This was due to the coincidence of the algorithm used in the problem, the algorithm source code from mine and asd7766zxc's are the same, but both were written and published before the start of the round.
I kindly request the Codeforces Team to review our submissions and source codes.
Thank you for your time and attention.
Best regards, jakao
Dear Codeforces Team,
I recently received a mail regarding significant coincides my solution (ID: 288582309) for problem 2026B, which may suggest a violation of rules. I don't know how my code coincides with others but to clarify that this is purely coincidental. i use DP approach to solve the problem. that is more common aprroch to solve this problem that may be the possible reason for the coincides the solution.
I did not reference or share code from any external source, nor did I use public coding platforms like Ideone with default (public) access. i used online gdb platforms with privet access for compilation. i make my own templete for the future contest so that coincides never happend in future (as i am new user and not aware of it.) that might be possible reason of this.
Thank you for reviewing this clarification.
My code was skipped due to code-matching, but it’s my original work without external help. Could you please review this, as similar logic used by higher-ranked users didn’t face the same issue?
Hi! I have received a message from the system that my submission 289199140 for 2032B - Medians coincides with 289209093. What should I do about this?
This was a relatively easy problem, and I don't think it's a surprise to have similar codes. Will I be considered a cheater for this by CF now? How can I erase this suspiciousness on me?
UPD : Now that I think about it, It can also be possible that my code was shared by someone else who was in the same room as mine and instead of sharing his own code after getting accepted, that guy shared mine instead??? I should not be held accountable if that was the case.
Hello! I've recieved a message saying that my solution 289236108 for the problem 2032C significantly coincides with more than 100 users, well i don't even know them, i was giving this contest in my room isolated. Problem too had straight forward approach, I've done that problem using binary search and i don't think there is any other method for that, So it's obvious that everyone will use binary search. The list too is damn big i can't even specifically say who to blame. So please see to this..
Hello Everyone, This morning I got a message from system that my submission solution 289281576 for the problem 2032C during the Codeforces Round 983 Div2 was similar to others and my account might get blocked due to this.
The submission was made by me for Question C, and i send it to one of my friends to help him .He must have sent the code in one of the telegram groups , so everyone copied from there.
I request the community to help me out here as I don't know whom should I contact about this.
I will post the link of the telegram links that he might have sent to :
https://t.me/codeforces_cp
https://t.me/codeforces_codechef_leetcodecppp
https://t.me/codechef_codeforces_leetcode_cp
https://t.me/codeforces_answers
your "friend" sent it but you have all of the tg group link, thats crazy
That's because I asked him where did he(or they, don't know with how many people he shared the code ) share the code and he sent me those links .
just stfu and take the L, even if this was true (i doubt it was) it's still a violation of the rules to ask your friend for help. just get better and stop making excuses
Lmao , I didn't ask him for his help , he did . And yeah I do regret sharing my code with someone else . He shared the code with others just for the sake of money . So stop making assumptions , I have been giving contests for a long time in other platforms as well and i don't need to submit someone else's code to increase my rating , it means nothing to me .I even shared my code with my friends a few times before but never got penalized for that , but this time that mf just shared it with hundreds of people on telegram . I will never ever share my code with others in the future and i will surely try to improve . Thanks for the advice though.
Subject: Clarification on Solution Similarity for Problem 2032C in Codeforces Round 983 (Div. 2)
Id: 289231171
Dear Codeforces Team,
I recently received a notice regarding potential similarity in my solution, suggesting it may resemble other submissions. I'd like to clarify that the approach I used for this problem is based on well-established techniques in binary search and subarray validation, tailored to find the minimum valid subarray size.
The algorithm leverages binary search over the possible subarray sizes (low to high), where each middle size is validated by checking subarray sums, ensuring they satisfy the constraints by sorting elements and checking ranges efficiently. These are standard practices for optimizing search problems and enable efficient exploration of potential solutions by validating within the bounds.
I assure you this approach is my independent work, and I did not reference or share code externally. This method reflects a conventional and logical approach to solving such problems without consulting any public sources.
Thank you for reviewing my clarification.
I think I have used ideone in default mode by mistake because I dont have idea that someone can see my solution there thats why my solution has been copied by somebody.
yawning_winner bro copies and changes the code from telegram
I really appologize,
i push my answers in github during the contest and it became a habit,
i am just a newbie and did'nt knew that plagiarism can occure in this way as well,
I will make the repo private from now,
lol, any more excuses you got?
Not asking for your approval, nor giving any excuse to you
I would like to clarify that the recent issue with my ratings was due to a coincidence, as I inadvertently published my code on ideone.com. I kindly request that my ratings be restored.
In CodeForces Round 984 Div 3 solution 289546852 for the problem 2036C coincided as the logic was used same or it might be the default setting of public mode in ideone .So please look into this and give my ratings back
It is very regretful for me that discussing the question's problem and different approach to the same solution reached me at this point where I had found no better approach to this solution which I solved myself but the same time , this code matching with the other participants , I must say is totally a matter of coincidence for me. But , what happened must not be done in any way ..so from next time. During my contest, it will be my first priority to find a approach to any solution myself only without discussing with others ..I accept my sincere apology for this time but assuring at the same time , no such violation will be upheld from my side after this ..
Dear Codeforces Team,
I am writing to request a review of my recent solution submission, which was marked as "Skipped" due to similarity with another submission. I understand Codeforces uses automated tools to detect possible cases of similarity between solutions, but I believe this case is unique and warrants a closer look.
My solution was generated with assistance from ChatGPT approximately one week ago for practice on a different coding platform. The solution code was based on general algorithmic knowledge and not influenced by any other Codeforces participant. This was an honest mistake, as I reused the code which I had used in practice, unaware that it might cause a conflict in an official contest setting.
Here are the relevant details for your reference:
Username:TheWiseKIng Contest Number:984(Div-3) Problem ID: 2036C Submission ID: 289543199 I kindly request that you reconsider the status of my submission, as there was no intentional attempt at code plagiarism or collaboration. I fully support the integrity and fairness of Codeforces contests, and I am more than willing to cooperate to resolve this matter.
Thank you very much for your time and attention to this request. I look forward to your understanding and a positive resolution

Hi MikeMirzayanov Codeforces Round 983 (Div. 2) Problem A Submission id — 289192116 Problem B Submission id — 289214425 Problem C Submission id — 289265297
My problem A and B logic is same as authors solution just their is change in implementation. As logic was trivial their can be multiple implementation similar to mine. Earlier I had different logic with problem C in which I was applying binary search on min number of operations, you can also check by submission id 289242175. After that I had observation that rather than applying binary search on min number of operations we need to do it on longest length of subarray so I stick to that binary search logic. So my approach for binary search on longest length of subarray was correct many others can have thought of same logic but their implementation differs yet I received warning, your solution 289265297 for the problem 2032C significantly coincides with them.
Please look into matter and resolve my issue, as I participated contest individually.
Hi MikeMirzayanov Educational Codeforces Round 171 (Rated for Div. 2) Problem B Submission id — 288571058
I received warning, on my problem B solution 288571058 significantly coincides with 288566877,288559479 and 288557948. We can clearly see solution 288571058 288566877 is written by an AI tool because of names of variables and function names. As for submissions 288559479 and 288557948 their code is completely similar like entire is_possible function used for binary search and right = (ll)1e18. While my code is completely different from above 3 submission yet I received warning.
Please look into matter and resolve my issue, as I participated contest individually.
from the past few contest, i solve all the questions by myself,
maybe the source of my learning matches with some people , or my approach may be widely simillar,
but that doesnt mean i am a cheater,
Kindly give me back my ratings
There's no way you suddenly solved four problems of div2 and div3 consecutively while you still struggle to solve Watermelon problems in practice. You better be honest with yourself.
don't make me laugh at your struggle
its not like i suddenly started coding, i have been practicing for some time, but started code forces recently
yeah, I can confirm seeing your rating. cheaters everywhere!
I don't care what u think, just cuz u got a higher rating for the 'time being'; . There are a lot who actually cheat and get pass these, I would say 'professional cheaters'.
thats crazy cuz i saw like 5 submissions that's almost 1:1 to yours just randomly opening submissions in the "Skipped" page in 2026C and 2026D
Does my answers match with yours??
shut the fuck up, no 2 people write codes (especially for long problems) in the same way you retard
I wrote the code (especially C) all by myself It took me time, I am not an expert like you
I don't know whom you are comparing with
your one matches with everyone like you who spends their time on Telegram during the contest xD firstly. have you ever written any solution on your own though?
https://drive.google.com/file/d/1dyPLtkrjZfOS9ZLpG1ClmaNiMqKDjIqI/view?usp=sharing
https://drive.google.com/file/d/11HnKRNQx7qTlqYBfD8R8xgHR44Iv-yP0/view?usp=sharing
i cant argue with someone who cant get what i am saying, you keep referring to telegram because u are accustomed with cheating from that. for your kind knowledge, i dont even have a telegram account, bcs i never needed one.
You uploaded these after the contest ended. Also, I did not get any skipped till now. I agree, CF misjudges sometimes. But you got skipped consecutively twice. So, don't act like you know nothing about that!
Thats the latest commit, which i did while practicing blackcell problem
From the past 3 contests i have been pushing my code in github, I agree it was my grave fault for making code public
I got skipped only on those which i pushed in the github, But i didnt spent so much time to be called a cheater at the end
it really hurts me that CF doesnt give any warnings, I am just a new player here and didnt know much about its surroundings,
https://github.com/Tahmid019
i dont see anything related? also some of the similar submissions that got skipped were submitted before yours
https://github.com/Tahmid019/cf_contests
The repo is public now, check it out. Also, some submitted before doesn't prove anything,
My Rating is already taken and cannot be brought back, I don't have any obligations now, to give (especially you) any more clarifications.
ur so retarded, you know you can't argue against the truth anymore so ur pulling this card, those codes were uploaded in a private repository so it couldn't have been indexed and copied
just stop lying and take the L, or maybe i should email your uni and maybe your employer to let them know that you're a serial liar?

[contest:https://codeforces.net/contest/2036/standings] Subject: Clarification Regarding Coincidence of Solution Code (289569959)
Dear Codeforces Team,
I am writing in response to the email regarding the possible coincidence between my solution (289569959) and several other submissions for problem 2036D. I would like to clarify the situation and address the concerns raised.
First, I want to assure you that I did not engage in any intentional rule violation or plagiarism. The similarities between my solution and others stem from the fact that I used Ideone to write my code, and by default, this platform sets the code to public, which may have caused the overlap. I had no intention of sharing my solution with others during the competition.
Additionally, I acknowledge that I sought help online for Python syntax as I was new to the language and wanted to ensure the correctness of the syntax, especially since I was informed that C++ code would not be accepted for this problem. However, the core logic and algorithm in my solution were written entirely by me, and I can confidently say that the structure of the code is original. If necessary, I can provide you with the actual version of the code as I wrote it in my local VS Code environment, where I compiled and tested it.
I fully understand the importance of maintaining integrity and fairness in the competition, and I am committed to following the rules. I request that you kindly reconsider any penalties or sanctions on my account, as this situation was unintentional. I would also appreciate it if you could restore my ratings.
Please let me know if you need any further clarification or details. I am happy to cooperate in any way necessary to resolve this matter.
Thank you for your understanding.
Best regards, kanhaiya_22
Lol just stfu
I have submitted my own written code in global round 27, but I got mail from codeforces that my solution coincides with someone and they simply gave negative points in contest.
please look up this query, You can check my all solutions of every contest, You will find the same way of code style.Its my own code but I don't know why they are doing this thing
So,day before yesterday, I gave the Codeforces Round 985 and was able to solve Task 1 and Task 2. Now, Task 1 is OK but received a warning on the Task 2 of the Round. Now, I have no idea how come my answer coincided with another person and this is the first time for me. I have below attached a pdf, showing my though process and how I went about writing the code. It is fairly simple, once you know how to use the Stack STL to solve this question. Pls resolve this issue ASAP

Hello Codeforces team,
I am new to Codeforces contests and to using Ideone, and I recently made an unintentional error by leaving my submission in public mode. Unfortunately, it appears that this allowed others to access my code. I sincerely apologize for this oversight and assure you it was not deliberate. I have learned from this mistake and will take extra precautions to ensure it does not happen again in future contests. I would greatly appreciate your understanding and request that no action be taken against my account. Thank you for your consideration.
I think logic used is same by everyone .Kindly review my code once again.There is no chance of coincidence.
I received a message that you copied question D from the previous contest. But I actually worked on it myself. Please check it out. If I'm being lied to, I'm not being lied to.
I did not even attempted D in the previous contest.Please check.
Kindly check it out!
I think the logic problem is the same for everyone so please review it, I solved it myself
Dear Reviewer,
I sincerely apologize for the situation and would like to express my respect for your dedication to your work.
Regarding the high similarity of the code, I would like to explain that this is because both my teammate and I are from the same university and belong to the same team. As a result, our coding styles and logical approaches are quite similar. However, I assure you that we did not communicate with each other regarding the solution, and this is purely a coincidence. I kindly request that you reconsider and lift the penalty.
Thank you, and I wish you a wonderful day.

Subject: Apology for Code Similarity
Dear Codeforces team,
I would like to sincerely apologize for the recent issue with my submission during the contest. I understand that there was a similarity with other solutions, and I assure you that it was not intentional. I might have mistakenly used a similar approach from an external source without realizing it during my preparation.
I am committed to learning and improving my problem-solving skills independently moving forward. I understand the importance of fair play and will make sure to strictly follow the rules in the future.
Thank you for your understanding.
Best regards, Jobaobada8
Dear @Codeforces team,
I would like to sincerely apologize for my recent submission as it was not intentional. I request you to please review my submission 292068794 once again. My submission must be completely different from others.
I understand the importance of fair competitive programming!!
Thank you!!
I received a notification about a similarity issue with my solution for problem 2037B. The similarity likely occurred because I used an online Python compiler during the contest, as I rely on public library computers and do not have my own computer. I now realize the compiler might have had public sharing enabled by default.I sincerely apologize and assure you this was unintentional. Moving forward, I will avoid using online compilers with public access and ensure compliance with the rules. Please reconsider this situation, and I promise it won’t happen again.
Hi MikeMirzayanov,
I hope this message finds you well. I recently received a notification regarding my solution for Problem 2037G as part of Codeforces Round 988 (Div. 3), stating it significantly coincides with others and might be a rules violation. I would like to sincerely clarify that my solution was entirely my own, and I did not copy from any other submissions. I previously worked on submasking enumeration using DP and I used these sources to learn https://cp-algorithms.com/algebra/all-submasks.html, https://pavan-kalyan.dev/posts/tips-on-dp-bitmasking-approach. Can you please help me in removing the penalty for the contest? If there are additional details or context you need, I’d be happy to provide them.
Thank you!
