During contest, I was stuck with C, but I saw that there was a significant increase number of people who had solved C. So, I thought that yes the contest might have been leaked again on YT. And guess what it was leaked. Hereby I am attaching some photos and links of YT channel and code of C (here c was solved by applying divide and conquer (D&C) approach in a recursive function as recursive function has O(n) Time Complexity so to reduce it, the leaker had used D&C to reduce time complexity to O(logn)

Image that roughly 2.5K people had seen it:

So, I would request CF community to consider this and make a rollback of rating changes and identify the cheaters.
Some handles (cheaters) having same code: Gladiator_King, Bhanu0p, itz_rao etc.

I didn't cheat, but I used Co-Pilot's autocomplete.
Your just said that Co-Pilot implemented some of the algorithms.It directly violates the rules about AI.
Oh sorry I didn't know that. I guess that makes sense then. Thank you for letting me know in the future.
dssfsuper2 Do you know where I can find the rules on AI?
youre not supposed to use AI in general during contest, thats a pretty good rule of thumb. to be more precise, you CAN access any content generated BEFORE the start of the contest. So you can't generate new prompts to AI during contest, cant access youtube videos or articles published after the start of the contest, etc
Thank you.
In this blog . Also every time when you register for a contest there are links to blog posts with all the rules that you have to follow
It has literally been advertised on codeforces since the rules were posted, weird that you missed it.
Rule restricting the use of Ai
Code Completion Tools (e.g., Copilot): AI-based code completion systems may be used, but only for syntax and minor coding suggestions. Using them to generate the core logic or algorithms for solving problems is not permitted.
You can see that the blog is 3 months old
In Mike's post he says it's allowed to use autocompleting tools
He changed the comment, initially he was saying that he used it to generate a lot of code and complex algorithms, not just that he used it. (You can see the original comment yourself if you click on the arrow next to "Rev. 4").
Now, I am curious to see that script!
Basically, a web-scraper with only certain websites to use
Yes, exactly, I want to see that script. If what you said is true, it looks fascinating to me!
I think other people might use it
You can't be serious! I don't think you sharing it here will make any more cheaters. The people who want to cheat can directly get it from youtube. And the reason I am asking to see the script is because I don't think it is easy to generate. If true, there is a lot for us to learn to learn from you, either in prompt engineering or in web scraping. So, can you please share the script or share the prompt that we can use to independently generate the script that can do what you just described...
a web scraper
C was definitely not that hard but i dont think it was easy enough for 5k+ submissions in contest
Every 3rd solution of C by the lower elos is copied from here i guess
Some did not even change the function names.
Actually, it is Recursive Function and on making patterns; you will observe the symmetry between left and right parts and can easily figure out the formulae and dependency of luck score on no. of segments.
Disappointing that the solution is leaked and the authenticity of this code is highly scrutinised.
You did the exact same thing bro: https://codeforces.net/contest/2053/submission/298876992 You just made it a lambda function and changed the "% 2" into "& 1" and some other small parts so I don't see why you're saying this.
so that's what I have pointed out. It's not tough to come up with this idea when you have spent a long time in observing patterns. And talking about changes, that's my coding style.. That comes naturally to you.. see my other submissions if you doubt that.. at least i am not making an excuse to use some web scraper and blah blah !!
I repeat there is no patent on this idea.. See BurnedChicken's code (GM).. he has also done almost the same thing.. Is he also a cheater ?? The only difference is time of submission..
but i need time to grasp things and patterns.
i don't care if i get skipped or banned.. none can deny my 2-3 pages of observations, having some AP idea, making new testcases, visualising for size = even when smaller TCs were for odd sized intervals..
Good for you dude.
Sorry but this was not in reply to you buddy.. this was for a pioneer in AI ML, who has a such powerful script in VSCode
I don't think you understand the difference
Stop yapping, just see your A and B submissions, that too copied from live stream.. And you are a specialist, you took so long to solve A or were you waiting for the streamer to upload solution ??
don't make excuses for that also.. there was a much simpler and intuitive solution to Problem A still, you chose such a complicated idea (exactly the same as pastebin code)..
don't really see the point of this argument.
why you took 1.5 hour for A bro, and solution same as pastebin code?
I know that much already , if u see my solution it is even simpler .
I just stated my opinion that i did not expect 5k+ submissions on the problem in contest
are they upcoming contest solution ??
OMG ronaldo on CF!!!!!
so even specialists are cheating now ?
Prolly they are Specialist due to cheating
There are many other submissions which match the exact same solution just with some added macros and preprocessors is there any way I can report them?
