Discussion of Problem 1830. Help in the RNOSmomo WA 29 test [3] // Problem 1830. Help in the RNOS 17 Jun 2011 17:33 Does anybody know what is so special about test no 29? I am positive that my solution is correct (which is obviously not the case) but it gets WA 29. I even compared it with a slow solution (BFS) but I did not find any differences. momo Re: WA 29 test [2] // Problem 1830. Help in the RNOS 17 Jun 2011 19:02 Please, I would really appreciate some help because I have tested all possible input combination for length 8 and the slow and fast solution produce the same answers.

I don't know what's wrong but the 3-d test fails my program with "Wrong answer". Well, I have checked it manually and everything is OK, answers are right. Is this a problem with your checking system?
