Give detail to which code for which box

3. (13 points) Write a function chessBoard(m, n) that takes as input two integers m and n, and returns a 100 x 200 NumPy array that represents an mx n black and white chessboard image. We assume that each pixel in the image is represented by a single real number between 0 and 1, representing the gray scale from black to white. Note: You should only use Numpy and Matplotlib for this problem. To get full credits, you should avoid using any explicit for/while loops.
