Sokoban
You are encouraged to solve this task according to the task description, using any language you may know.
Find a solution to a given Sokoban level. While move-optimal or push-optimal (or any other -optimal) solutions are better, this task only requires finding a solution.
Sokoban levels are usually stored as a character array where
- space is an empty square
- # is a wall
- @ is the player
- $ is a box
- . is a goal
- + is the player on a goal
- * is a box on a goal
Sokoban solutions are usually stored in the LURD format, where lowercase l, u, r and d represent a move in that, (left, up, right, down), direction and capital LURD represents a push.
Please state if you use some other format for either the input or output, and why.
