Hello Codeforces community, Recently I have started to notice that many solutions that I write are pretty slow, although it's always right solutions (they were intended by problemsetters). I've tried to look at code of red participants but didn't find any crucial difference in style of writing. There is one example of problem which I've tried to solve many times, but it didn't pass all the tests (due to TLE) http://codeforces.com/contest/719/submission/21066177 (the problem is http://codeforces.com/problemset/problem/719/E) Could you help me with it? If yes, please, could you tell me what makes my code so slow?
Thanks in advance for any help.
