Rating count had changed after rejudgement of some contest including Pinlay Round 3. But some remained uncaught.
Solution of Problem B :1909B - Make Almost Equal With Mod of a user during contest is exactly same, just changed the variable name {rem1 , rem 2} to {r1, r2}.
After analyzing the two submission, I realized the contestants are exactly one person. He uses one CF handle to backup his wrong submission penalty and use other handle to submit the accepted solution.
This guy has cheated in 5 contest in this way and having a good time now. /predownloaded/1a/62/1a62c882a3434276bf39870d6130c0f10f970f8f.png
A request to codeforces authority to rejudge the previous rounds once again if possible. If not possible , please make a solution to prevent cheating.
Happy New Year and Best of luck codeforces.
