For the Codeforces Round 725 (Div. 3), check these two submissions: 119070732 and 119073742. These two codes are 99% similar. These guys are new type of cheaters. They cheat by exchanging codes and this is not the first time. So would you like to explain your actions, lordgavy01 and zoldyck. For further proof, check these two as well: 119047376 and 119057342 (the function is same and only variables are changed).
They have also plagiarised in Codechef contests as well (obviously). What do you gain from this?
