Can someone please identify the problem with the submission 24848243 . It got hacked during the contest by Endagorion and I resubmitted it by removing the floor which I had used unnecessarily while computing total range for a given n. I don't think it should make a difference though. Resubmission ID : 24860951

Thanks in advance.

Thank you codeforces for adding magic into our lives.

Good luck to everyone! Hope we achieve new heights in 2017 .
