Hello, I see this submission 255358007 and 258452885 (these are from 2 different round)

This submission clearly obfuscate the code. He put 30 DFS function into his code, plus a unnecessary segment tree

He also obfuscate every code in every round he participate in.

This prevent people from hacking the code, which make the round unfair. Also, the plagiarism checker can't check their submission.

I request MikeMirzayanov to ban this account.
