DWITE 2008-2009 Round 4

Today is the 4th round of the 2008-2009 DWITE contest and we have 385 students and 171 teams from 38 different schools participating in today's contest.

We are still having an issue with Google Chrome and Safari (and probably all webkit based browsers) uploading files so please use IE, firefox, mozilla or another none webkit based browser for the contest.

Also a note on line breaks. Our input files will be using the Windows line break format of \r\n and not the *nix format of \n so please make sure to take this in to account in your solutions (tho the best bet would be to account for both possibilities). The judge should be able to read either format for your output.

Good luck and have a great time!
