Imagine an infinite chess board. The cell on the bottom-left most corner is labelled (0,0)(0, 0). The cell on the right of it is labelled (1,0)(1, 0). The cell above (0,0)(0, 0) is labelled (0,1)(0, 1).

The colors of the cells alternate such that no two adjacent cells share the same color. The cell is colored either blank or white. The bottom-left most cell is black.

Given the label of a cell, you have to determine whether whether it is black or white.

Input

The input will contain two integers AA (0A10100000000 \le A \le 10^{10000000}) and BB (0B10100000000 \le B \le 10^{10000000}) representing the cell labelled (A,B)(A, B).

Output

If the cell (A,B)(A, B) is colored black, print “Black”. If it is colored white, print “White”.
