Hello guys, I found out that Problem H at ICPC 2021 (which was yesterday) is not an original problem which sounds very weird, i wonder how such an event does not have its own original problems.

ICPC problem set: https://icpc.global/worldfinals/problems/icpc2021.pdf (problem H)

The original problem: https://codeforces.com/gym/101341/problem/A

Today while i was hacking some solutions i've found a code from dark web and this guy's submissions are the same here's one of them i think he's a cheater and only doing this for avoiding plagiarism https://codeforces.com/contest/1744/submission/176588974

Update: His solutions got skipped
