Do they have the same color?
Given a standard chessboard, we would like to know if two coordinates have the same color.
The input first lists the first coordinates - r1 (row) and c1 (column), and then lists the second coordinates - r2 (row) and c2 (column). Print Yes if they have the same color, and No otherwise.
Hint question
Can you think of a smart way of detecting the color of the current position? Do you notice a pattern when rows and columns change?
