Discussion of Problem 1369. Cockroach Race

How to pass test #32
Posted by Sid 21 Aug 2006 10:22
As I know author supposed to use quadro-tree structure for solving this problem. But in fact the may exist non-random tests that solving this problem such a way is impossible. For example a large circle of cockroaches and a lot of sweets in center. My problem stucks on such tests so I suspect that test#32 is something like that. So how to pass such tests?
