Snake

Snake is a video game in which the player controls a snake-like creature that grows longer as it consumes objects scattered on the screen. When the ever-growing creature collides with obstacles, terrain boundaries, or itself, the game is over.

Each argument is a series of the creature's movements: left, right, and forward, denoted by L, R, and F respectively. The snake always starts its track in the upper left corner, facing east. Furthermore, it never intersects itself and leaves no terrain along the north and west sides, both of which would end the game.

For example, FFFRFFLFFFFLFLFF indicates the snake's movements are:

• Move three cells forward
• Turn right, facing south
• Move two cells forward
• Turn left, facing east
• Move four cells forward
• Turn left, facing north
• Move one cell forward
• Turn left, facing west
• Move two cells forward

Using hashes, the aforementioned trail is visualized as follows:

   # ###

For each argument, print the creature's trail, separated by newlines, and print an additional hash on the terrain square that concludes each trail.
