In the recent Codeforces Round 897 Div.2, I have discovered that many of my friends have copied the exact code for questions A, B, and C from a publicly available Telegram channel. They then modified the variable names using ChatGPT before submitting the code.
MikeMirzayanov my concern is whether there will be any plagiarism checks for questions A, B, and C. None of these questions were simple formula-based (like a*b), so, in my opinion, there should be checks in place. If there are plagiarism checks, how confident are we that they will detect such cases (where only variable names were changed)? So far, no action has been taken against them, and I wonder how many others have done the same thing.
