I am currently trying to solve Problem E Croc Champ 2013 Qualification Round, 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 1: try to copy and resubmit some accepted codes (sorry guys) and all of those solutions also time out at test 30 :(
Update 2: Finally get it accepted, thank you Mike for your help :)
Auto comment: topic has been updated by alibaba (previous revision, new revision, compare).
It means that some tests have been added after the round.
The most recent solution (for Java) is on 08-April-2015, and it only contains 28 test cases, and when I resubmit this solution, it's also time out. I don't think Java user can get this accepted without increasing time limit.
It means that I've added a test later. You are wrong about Java solutions (3524569), your algorithm seems to be unefficient.
Thank you for your effort Mike :) I will improve my solution.
