Chess

Mr. Fuad loves chess so much. He only knows king's move. Now he has K kings and a "special" chess board with size N X M. He wants to know the number of ways to put K kings so that none of them attack each other.

OutputTo the standard output write one number that is the number of ways to put K kings on the chess-board so that none of them attack each other. As this number can be very big print it with modulo 1000007.
