I know this has been put up many times by other Codeforces users, but I need to write this blog using some proofs that there are many cheaters that use ChatGPT during contest. Old Codeforces users can see that number of Div2 C and D submissions have been increased post AI boom.

Now let's discuss about the last round i.e. Codeforces Round 1101(div 2). I figured out that there are many users that simply put question in the prompt and write the code provided by GPT. For example, let's take the Div 2-C1 Seating Arrangement (Easy version). I couldn't solve the question, so I was checking some solutions of other users and figured out that many of them has exact same solution for this problem. Then I went to chatGPT and pasted the question. Guess what, it gave me exact same solution.

You can see that these users — (krish_patel20, Bugs_Bunni, InvernoFrio, maverick_kb) have the same solution for C1 and if you use the AI model, you will get the same exact solution for this problem.

Submissions — 376670029, 376674270, 376664822, 376664639.

I want to ask these users that what you get ruining others hardwork and what you will do with your rank which you achieved by cheating.
