Cheaters Solving F in Round 968 Div 2
By atmos_nemesis, history, 3 months ago, In English

These guys yamin401533 , saptarshi8103 having the submissions 278124502 , 278145701 respectively have similar solutions for The F problem in today's contest(Codeforces Round 968 (Div. 2)).I wonder how these newbies and specialists are solving F problem. I would request MikeMirzayanov to ban them.

I had been trying a dp tabulation solution from the very beginning. But my code was giving errors in some test cases when I used GPT(GPT-4) to debug my code for a few test cases it suggested this solution. Running on the example test cases it was passing. It was also passing few test cases I prepared, so I submitted it and got cleared. I think the other person has also searched in GPT for a probable solution and got that similar suggestion. And it is not illegal to use GPT during contest as it is nowhere mentioned as an offence

    I have not copied from anyone. If you feel so then check my solutions of questions upto C. Moreover, if I had an intention to cheat and increase my rating then I would have cheated for D and E as well. I am saying if you have acsess to gpt-4 go there and copy paste the question F I believe that you will get the same solution as mine.

I find that the solution is matching with only another user, that is, yamin401533. So, it should be that I must have got the solution from him because nobody else has submitted the same solution. Moreover, that person was struggling solving B, so it means that he might have also got the code from someone else. But surprisingly there exists no other similar solution from any third user during the contest. I hope that this makes sense.

    With cheating, you are insulting your clg, parents and even your country.

    Explain those lame excuses to those who have never coded in their life.

    And also if your code was not able to pass the samples, then your code was completely wrong and didn't have any error.

Ravi_21 check this guy out. Not only he was plagiarized on multiple occasions but also on multiple platforms.. He basically has zero knowledge and have been plagiarized earlier on CF. He uses multiple TG groups to collect answers and submits on CF. MikeMirzayanov please take a look into this. I will find the submissions which matches his submissions and update this comment again. He solved upto E in previous round.

I wonder if these submissions are legit below:
278065706 278069623 278100106 278130211 278137219

I heard that submissions like those are against the rules

    Yes, GPT-4 is very powerful. It is able to do it. But, I guess it is not your mistake.

I am from his college and I have a story to expose his cheating racket with all proofs and evidences. I want to write it as a blog but can't as it says I am not a trusted participant. I can't do so from my main id since people of his club who are also involved in this thing will get me in trouble and force me to take down the post. I am a final year student and I don't want any matter to hamper my placements. How to write a blog anonymously or with a fake id like this? Also if I expose them with this account there is no way for them to get my email and know me right?

Hello Guys. I am from the same college as saptarshi8103 and I am a final year student. I would like to expose him and his whole group and racket of cheaters. I will post a blog with all the evidences like screenshots of code leaks and messages in his group etc. Since I have my placements and I don't want bad relations with the TPR who happens to be his friend, I won't be revealing my identity.

So this guy is a member of a club called RECursion and as you can see on this page, their official site, he is the contest head of the club. This is the official Competitive Programming Club of NIT Durgapur, our college.

Before talking about him, let me go to the roots and actually expose what his club does from the inside. 2 years back, when I was in my 2nd year, I appeared for the auditions of this club. I cleared the initial rounds of the auditions and in my final PI, I was auditioned by a senior who happened to be a Candidate Master. He is vishaaaal. He asked me have I ever cheated in CP? Back then I just did DSA and wasn't into CP so my answer was a clear no. He then told me blatantly — "Do you think I could ever become a candidate master if I sticked to these morals? Competitive Programming is meant to be competitive and we have to stay ahead of competition by using any means. If I was as idealistic as you I might not have gone past specialist."

During our class orientations, this club used to tell us that anyone will become a top notch competitive programmer if they joined this club and how every year only teams of this clubs get into ICPC from our college. Later, when my friend got into RECursion, he told me every year people who get into ICPC from this club are always that year's ICPC heads. You can note this years ICPC heads of this club here and see that they will be the one going this year. The reason is, to maintain its legitimacy so that no one other than they stay the top CPiers from this college, the whole club helps the team of the selected 3 in the online rounds of ICPC and last years team had the same story. You can see here, the profiles of the guy who made this post and was from the second team to qualify from this college happens to be from recursion. The other team to qualify from this college, as you can see in the screenshot of that post is titled RECmates, REC for RECursion so I dont need to say where they came from. All this because the whole club gets into finding solutions for those 2 teams they decide to choose for ICPC usually covering all ICPC and contest heads of this club. They even run a "fund-raiser" in their club from the 2nd and 3rd years, to which final years also contribute, to hire people who can help them clear those online rounds and dominate ICPC.

Apart from that, they run classes to teach CP to juniors before their auditions. Today was a class too. I appreciate the fact that they are teaching concepts for free but some of them cover topics like THIS. I wonder why anyone would want to learn/teach this topic!

A comment would be too short to mention all of their scams and promoting cheating culture. Forget about OAs they mass cheat in online OAs as a club and their good members who are legit specialist level and cheated their way to experts clear OAs of their juniors of the club and also help people outside the club in exchange of money or other "favours". This guy mentioned in this post is just a mere member of this club. Not his fault he is at a place which has a culture of this. Cheating is OA has become too common in Indian colleges but clubs like these lay the foundation stones for that and legit people don't get jobs. If you confront them offline, they just say "it is about competition and competition isn't just about fairness but about how you can play with the rules without being caught". Because of this Competitive Programming has become Competitive Cheating here. Their classes have convinced people CP is both about problem solving and about how to copy codes without getting plagarised.

Too much for this comment. You all can visit their site I have linked above and do a hunt for the codeforces profile of the members. I can't mention them all here else the comment will be too big. You can also compare if the members of this club are giving same contests the submission timings of the members are quite close because code sharing is common among them. For hunting for the profiles, get the identity of members here and search their codeforces profiles here. Will take time but you will uncover many such things. Some of them have their accounts with their real names rest you might also find it through linkedin.

And there are many more scams and cheatings done by the members of this club. I will be making future blog posts or write comments about them if I am not caught. I have plenty of more screenshots and pictures.

these solutions are way too similar, anyways I believe this answer is not generated using gpt 4, as when I am looking for the solution for the same problem GPT is unable to give me this same solution.

So I want to know how these telegrams and other stuff provide solutions, even when AI is not able to give solutions.

      ohhk so basically some human is solving, but then why spread the solutions? until and unless someone is not paying at least $300-500

      I mean I can understand someone sending solutions to people for this much money. But then who can be the idiot paying this much just for cf solutions

        market rate for D solutions is 30 rupees (INR). Thats 0.36 Dollars. E and F can be 0.75 usd and 1.5 usd though. Thats the indian prices of this. Foreign leakers charge way more like 7 dollars for F

Majority Indian are cheaters, mostly from tier 1 colleges. Education cant teach them morals. Using Cheating as a shortcut is not smartest but mere a short time happiness. These guys have no religion , beliefs, and Self Respect but they are just guy whose parents also have cheated surely. Ending lifes of peoples whose parents earn money honestly to teach their children so they may got some job, but then their comes cheaters in every field they Only care for Money and success through shortcut. God sees their plan but he plans better. You will face consequences of Cheating in your life for sure. cheating in places where other lifes and success and hard work matters becomes inhuman crime,while cheating for other reasons which does not impact others is fair.

Criminals because they Cheat to destroy someone deserving .Don't tell me u deserve from your cheating which is your skill just because u were smarter in cheating, however if u say this openly u will be beaten in society where u live and u can only bark against defending your action of cheating. Better die hanging
