A has a large chessboard. There is only a "bishop" on it. He wants to know if the bishop can jump from the starting point(x1, y1) to the ending point(x2, y2) using one jump.

The "bishop" moves like this: it can move from (x,y) to (x+2, y+2), (x-2, y+2), (x+2, y-2), (x-2, y-2).

Inputs four integers(x1, y1, x2, and y2) that represent the position of the starting point and the ending point.

If the "bishop" can jump from the starting point to the ending point using one jump, output "Yes", otherwise output "No".
