title: Cover large rectangles with identical small rectangles
body: <p>The problem states that I have a big rectangle, with dimension L and W, and unlimited number of identical small rectangles, with dimension l and w. L * W is guaranteed to be larger than l *w. So I want to find out the maximum number of small rectangles that I can put into the big rectangle, without overlapping. You can put the small rectangles in any orientation you like.</p>
