For this boot up your goal is to draw a NxN checkerboard that is sized to be
90% of the smaller dimension of the drawing area (width or height) and
centered within the drawing area horizontally and vertically. Your image
should look something like the picture to the right.
Writing this method will require using a loop, probably two. You will also need to get the computer to do some math for you to figure out how big the board and squares should be and where to draw it so it’s centered.
