UPD: it seems that the problems are visible now.

This is a reminder that USACO January contest starts soon on January 15 and lasts till January 18.

UPD: Contest is over. Feel free to discuss the problems.

The same code for 580D - Кефа и блюда is accepted using GNU 13170436 and gets TLE using Microsoft compiler 13156910 . I do not know the reason for this, but I think GNU optimizes recursion more than Microsoft.

Anybody knows the reason for this ?
