Can Someone Draw this image using procesing?

Write a program that draws a chess board as shown below. Assume that the size of the window is 400 by 400 pixels. Each square in the checkerboard is 50 by 50 pixels. The checkerboard contains 8 rows of squares and 8 columns. The squares are red and black. Here is a tricky way to determine whether a given square is red or black: If the row number and the column number are either both even or both odd, then the square is red. Otherwise, it is black. Use the conditional and iterative flow control to finish this drawing. Here is an image of the checkerboard:
