I have no idea how to solve this problem. I even don't find any other way. my submission: https://codeforces.com/contest/1618/submission/249522519 my other submission that might have more optimization:https://codeforces.com/contest/1618/submission/249523839

Hello code forces, this is my first blog entry as a newbie and I hope it'll be answered (I don't become surprised if nobody answers me! the problem I have is a misjudging happening in my code's judging. I noticed while reading the first test cases that my code returns something else that what is written there as "output", I mean when I give the very same test to console it returns the right answer nevertheless it shows my code outputs something else. if needed https://codeforces.com/contest/1894/submission/237543088 Sub no.237543088 who should I go to?
