Hello MikeMirzayanov, Hope you all are fine, me too. My previous account : https://mirror.codeforces.com/profile/S9M0N_R3L3Y_GH05T got disabled, I am extremely sorry, I did take help for solving my C to get less negative delta which I shouldn't have. I will never ever do this again.I beg apology. Kindly let me use my previous account. Sincere apologies once again. Also this is not my alternate account , I just wanted to make my little brother enthusiastic about problem solving and made this account for him, unfortunately he isn't into these. Thanks for reading.
