You are given a rectangle, which is defined by its width w and height h, both positive integers. We allow a rectangle to be cut into two smaller rectangles with either a straight horizontal or a straight vertical cut at any integer position. For example, one of the possible ways to cut the rectangle (5, 8) in two pieces would be to cut it into (2, 8) and (3, 8). Another way would be to cut it into two pieces is (5, 4) and (5, 4) etc. The resulting smaller pieces can then be further cut into smaller pieces, as long as the length of the side being cut is at least two to allow a cut. You are NOT allowed to cut multiple pieces in one motion of the blade by stacking pieces on top of each other.

Your task is to keep cutting the given rectangle into smaller pieces until each piece is a square, that is, the width of each piece equals its own height. This is always possible, since you could just keep cutting until the size of each piece has become 1-by-1. However, this function...
