Imagine an infinite chess board. The cell on the bottom-left most corner is labelled . The cell on the right of it is labelled . The cell above is labelled .
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.
The input will contain two integers () and () representing the cell labelled .
If the cell is colored black, print “Black”. If it is colored white, print “White”.
