While she is bored, an idea appears in his mind, she just playes the checkerboard game.The size of the chesserboard is n*m.First of all, a coin is placed in the top right corner(1,m). Each time one people can move the coin into the left, the underneath or the left-underneath blank space.The person who can’t make a move will lose the game. kiki plays it with ZZ.The game always starts with kiki. If both play perfectly, who will win the game?

Input

5 3
5 4
6 6
0 0

设p为后手赢的情况，n为先手赢的情况。在棋盘上画出走的情况，易得m==1,n==1时，只有一个p，当n==2,m==2时，除了右上角为p,其余全为n，因为只要走一步就到达终点
