malikhuhuna5 and bdyby2010010 are cheaters, because their code of prob E https://codeforces.me/contest/2075/submission/311102615 , https://codeforces.me/contest/2075/submission/311093253 is same as https://www.youtube.com/channel/UCkDyE8XB-J7QWxnE5zkj_cQ/community?lb=Ugkx6_J_H7Ckk4-TvK89oU-nKG3k8G0phENq
ban them plz
UPD: I have found that there are a large number of players whose E codes are similar to the two codes above, which is probably a large-scale cheating case.

And flork It seems to have been used Chatgpt to solve prob D.
This is a very terrifying thing because a large number of cheaters even entered the first page!

Ban 2 cheaters at least, I want to have 4500 rank in this contest.
Looks like you'll get a huge promotion.
maybe if I don't get hacked lol

I think uk_024 and yebaiii are cheating too. uk_024's cheating is obvious, he adds template on the top to pretend like normal person, and yebaiii cheats by adding many extra, unnecessary variable names to avoid detection. I discovered this because code B appears to be too similar to that of many cheaters.
Can we just make it so accounts that go from placing < 10k for over 10 contests get instantly flagged if they score < 500th. I can't think of any other reason how they would achieve such a ridiculous performance increase(except if it was like a GM trolling, in which case they would have a couple random high ranking contests, not continuous sub 10k placements)
This is a good idea, although cheaters could (and likely would) make new accounts that would always perform well due to cheating.
what if someone who's 10kth place takes a break for a year to practice then comes back and gets < 500th on their first contest after they return?

Total Cheater Death
no I do not know any of the other people mentioned here and I wrote the code my self. maybe this is just the way to solve the problem and many people realized this themselves. I dont get why you wrote me in the list
alr, maybe you had a pure "coincidence" and thought of the exact same solution as the youtube video "coincidentally". however, that doesn't explain your submissions for D, which include useless stuff such as "unsigned long long" and "static". moreover, your code style rapidly changes from using snake case in E to camel case in F. you're fooling no one buddy.
What are the similarities between my solution and other users' solutions? Will there be some argumentation of your words and proof that my code refers to someone else's solution? I use an automated code obfuscation module, which is not prohibited by any Codeforces rules. And if you have some guesses, you should substantiate them, not make a list of “cheaters” based solely on their rank...
Go on tell me more shit .
rules
"It is forbidden to obfuscate the solution code as well as create obstacles for its reading and understanding. That is, it is forbidden to use any special techniques aimed at making the code difficult to read and understand the principle of its work."
Hmmm, I didn't see that post, only saw the general rule book
I want to clarify that I am not a cheater. Similarities in code can happen naturally, especially when solving well-known problems with standard approaches. It’s important to remember that having a lower rank doesn’t automatically make someone a cheater—many factors contribute to rank, including experience and the learning process. I’ve always followed the rules and approach challenges honestly. Let’s avoid jumping to conclusions and ensure that accusations are based on solid evidence, rather than assumptions.
This is an AI-generated response, isn't it?
Nope, wdym?
I mean, I may be wrong, but it feels unnecessarily formal
Nah, It’s just a habit of mine to write like this
it's definitely AI generated.
Bro can’t even defend himself without cheating, this is crazy level of shamelessness
Definitely. Only AI would use — instead of — (they former is not even on most keyboards). It also sounds so AI generated.
firstly, i didnt cheat and i can prove it. secondly, i used this time not ideone.com, i used this time for compiler onecompiler.com and i didnt know that its opened for everyone. i really didnt. but i can prove whenever you want. which question you want. if you couldnt solve the problem D and E, it doesnt mean that everyone who solved, cheater. but i know every contest has a cheater, but not only <=500, you should also check >=500, so after that would be fair.
Saying that other cheaters exist outside of the top 500 doesn't alleviate any of your guilt
And there is not enough time to check tens of thousands of submissions from low rated users
The only solution to this cheating problem is Phone Verification and IMMEDIATE BAN on the account caught in cheating. or atleast Red mark their profile to indicate as cheater so that it become useless for them otherwise codeforces will lose credibility.
This person is the stupidest cheater. He has submissions in java,c++,ruby. Doesnot even bother to remove the comments. And he is a university student. I don't understand how these morons even get an admission.
This guy sarthak1221 solved from A to D in a very small interval of time and also has a very strange solution for D, I've never seen anything like his code.
It's not strange — it's an almost exact replica of this one: comment
im sorry to say , but there is no point of reporting cheaters, ive done it for the last round and previous rounds , except the author chromate00 , no other author or whoever is incharge took care of removing the cheaters. Especially in the 1007 div2 round and the other recent one. Rollback already happened and everyone turned a blind eye to this.
I believe cry and the team was able to remove cheaters from a former contest
Cheater demolition. Nice work man.

ok i swear im like pretty sure more than half of the ACs on E is cheated
Computing bitwidth using temp variable is standard suggestion using github copilot and I would consider boilerplate code. Furthermore, given two long integers, it is norm to compute the max bitwidth. See full video with suggestion here: https://www.youtube.com/shorts/tTiqiVYTA7U
Furthermore, chatgpt's latest versions (atleast as of o3 mini to date) cannot solve problem E (I have tried this multiple times after the contest). It is possible future versions do. The core idea is to break down the problem into a digit dp version which is non-trivial. Once the digit dp part is identified, the rest is standard.
example suggestion
Update: Seems like o3 mini high could solve after several attempts. However, many of these solutions are still not considered cheating as long as the primary method involves using the variable name temp to compute bit widths.
