8 Puzzle
8 puzzle is a sliding puzzle that consists of a frame of randomly ordered,
numbered square tiles with one missing tile. The object of the puzzle is to
place the tiles in the right order (see picture) by using sliding moves to utilize the
empty space.
You can read more about this kind of puzzle on Wikipedia.
Our puzzle is presented as a 3x3 matrix with numbers from 1 to 8. Zero is the empty cell. You can "move" the empty cell in four directions: up--"U", down--"D", left--"L", and right--"R". You need to return a sequence of moves to solve the puzzle....
