During the last contest (Codeforces Round #634 div3) for the solution of ques D, I submitted multiple solutions which differ from each other very slightly (in order to micro -optimize code to reduce execution time). Now I recieved an email from codeforces that I have cheated. This feels very wrong as I never cheat. Please look into the matter @MikeMirzayanov
As you can see the notification in the top of the site
Some participants received an erroneous notification that their code matches their own code, this will be fixed.
, your case also could be one of those cases.
