##### DWITE Online Computer Programming Contest, October 2010, Problem 3

You are given a rectangular floor that is to be tiled with square tiles. The tiles come in a variety of sizes, but they all measure in some power of two: , , , , etc. A space can be tiled with of the smallest tile, but the minimum number of tiles required is only . Refer to the pattern below.

The input will contain 5 lines, a pair of integers , separated by a space.

The output will contain 5 lines, the minimum number of tiles necessary to exactly cover the by space.
