设有n*m个方格的棋盘（1<=m,n<=100），求出该棋盘中包含多少个正方形、多少个长方形（不包括正方形）。

例如：当n=3，m=2 时

正方形的个数有8个；即边长为1的正方形有6个；边长为2的正方形有2个。

-with n * m box at the chessboard (1LT; = M, 4; = 100), obtained the chessboard includes the number of square, the number of rectangular (including square). For example : when n = 3, m = 2 square with the number 8; That is a side length of the square is 6; Side 2 is the square two.
