I already have AC for this task with two different solutions. Now I submited new optimal n^3 solution, but it has WA5. Help me please.

It is my solution. It built on Preflow-Push algorithm.

When I wrote Preflow-Push algo (it got WA at first time)
simple tester which uses AC solution momently helped me...

Thank you. I correct my solution, and now it gets AC in 0.031 sec. http://acm.timus.ru/status.aspx?space=1&num=1421&author=44762

Can you tell me (elmariachi1414(at)mail.ru) how to implement solution, that works for 0.031 sec?
My implementation of Relabel-To-Front works for 0.25
Thank you!
