Please note that the user I am referring to is [user:nihaaleee,2026-03-22].↵
↵
After briefly reviewing his/her submissions, I suspect that this user may be using a "high-tech assistant" (a.k.a. an LLM), which I will explain with a few pieces of evidence that I have collected:↵
↵
1. All of his/her submissions are commented very carefully and neatly. (For more details, check his/her submission page.)↵
↵
2. Even though of his/her great performance in the round, he/she still received some "WA on test 1" on some very trivial problems, for instance, Problems A and B ([submission:367607999], [submission:367607609], and [submission:367620091]). Moreover, after each failed submission, the comments kept getting more and more detailed.↵
↵
3. After switching from Python to C++ after Problem B, we can see that he/she used "if (cin >> t)" ([submission:367643392], [submission:367648870], [submission:367651867]) and "if (!(cin >> n)) return;" ([submission:367643392]), which is a very significant sign of the use of LLMs.↵
↵
These are all of the signs that raised my suspicion about this user. Thank you for reading.↵
↵
If I have falsely accused or caused any inconvenience for [user:nihaaleee,2026-03-22], I sincerely apologize in advance.↵
↵
I hope to help Codeforces become a better and fairer place to compete and learn for everyone.↵
