http://mirror.codeforces.com/contest/242/submission/39896396 why my soltion gives TLE while other solution with same approach got accepted Can anyone help me out .Please Don't Downvote i already got -23 Contributions.
UpD:with use of treemap it got accepted but with AbstractMap.SimpleEntry it get tle is it bcz of bad hash function implemented in AbstrtactMap.SimpleEntry ?
