Maze with the stack to achieve the basic idea for solving the problem: If the current position can be adopted, in pressure, otherwise the next location to explore, if a dead end, then back to New Moon, the size of the maze: M* N. maze set up a custom. A simple maze to solve the problem is: starting from the entrance, along a certain direction to explore, can walk, then continue to move forward otherwise return along the same route, a direction for further exploration, until all possible pathways are exploring to date. In order to avoid going back to have access points (including the current path and current path in the point), all the points should be entered mark.
