I had a issue today in div2 Round 872 (Div. 2) solving problem A,B,C and Codeforces Round 871 (Div. 4) solving A,B,C,D,E. I didn't cheat and got a skipped . I think this is unfair, say in div. 4 problem A is even less than 20 lines of code . I wanna point out that similar ideas may imply codes that are somehow having nearly same implementation especially this problem doesn't need anything beyond an idea and a short code. . I request an appeal from Codeforces Lord
