I am currently trying to solve [Problem E Croc Champ 2013 Qualification Round](http://codeforces.net/contest/291/problem/E), and there is strange thing happen:↵
↵
My solution time out at test 30, but when I opened other's solutions, their solutions only have 27 tests, some have 28 tests, but none have more than 28 tests. Any body know why? ↵
↵
Update: try to copy and resubmit some accepted codes (sorry guys) and all of those solutions also time out at test 30 :(
