Hello, I see this submission 245823897 from One_Last_Trie.2 .

This submission clearly obfuscate the code.

This prevent people from hacking the code, which make the round unfair for contestants in room 538. Also, the plagiarism checker can't check their submission.

I request MikeMirzayanov to ban this account.
