Hi, This concerns two solutions of the same problems (problem D round 136 div 2 Link: http://www.codeforces.com/problemset/problem/221/D ).

The player, zhaozhiyun, submitted a code VERY similar to mine. His got accepted while mine got TLE'd. Here are the links to the two solutions.

His, Link 1: (Accepted one) http://www.codeforces.com/contest/221/submission/2081857 Mine, Link 2: (TLE one) http://www.codeforces.com/contest/221/submission/2078483

Can anyone tell why mine got TLE'd while his accept even though we have almost the same codes ?

Is it because of different server load during system test, etc ?
