Hi!↵
↵
i am trying to solve this problem [KPMAZE-Maze](https://www.spoj.com/problems/KPMAZE/) on spoj .. which i could summarize to count the number of spanning trees in a small graph (at most 25 nodes)...i tried Kirchhoff Theorem but i couldn't calculate the cofactor of Laplacian matrix..any ideas or code.
