I am getting runtime error on this problem https://codeforces.me/contest/3/problem/B on some ending test cases. My soultion is https://codeforces.me/contest/3/submission/55215191

I don't know what is right place to ask help regarding questions. I am solving http://codeforces.me/contest/1100/problem/B I read tutorial which solves it in O(m), but my solution is also of O(m), and I am getting TLE. Can someone suggest me the improvements? This is my solution:http://codeforces.me/contest/1100/submission/48488959

I got this error while solving 988B — 28. Is there a problem in my code or there is problem in server?
