So there is this guy tensorcore that he did E in 41 minutes, nothing special. The only thing is that it was his first problem done. After that, I decided to check all his submissions, an he has no WAs or TLEs, all AC. Like all 6 problems from the Educational Codeforces Round 185 (Rated for Div. 2), done in like 25 minutes. He wrote all his submissions (all of them) with a lot of comments, and after solving E in 41 minutes he's done C in 4 minutes, B in 6 minutes, A in 3 minutes (nothing special here), D in 7 minutes and F in 5.

Here is his submission for F: 351039844. I mean it looks hella suspicious, like describing every point of the solution, even the complexity and the fact that you are outputting all the answers seems a lot like AI work.

If anyone knows anybody that deals with cheaters on here, please announce them abt this.
