I have written code of this problem. Than i send it for proving. I've got a time limit. In half hour I send once more and got AC. Somthing wrong with computer timer.

1. As for timelimits in general. If your solution works almost as long as timelimit permits, sometimes you may receive TLE, and sometimes you may receive AC. Execution time depends on many reasons and may vary within several percents.

2. As for your very case. Your solution has get AC within 0.17 sec. It is not very fast, but fast enough to get AC. If your AC and TLE solutions were the same, we are sorry for TLE. But it may happen, and nothing else can be done against it.
