Figure 1: A properly formatted encoding
2 One Player, One Move
The first part (onePlayerOneMove in the file csce322homeWork02part01.js) will take in one (1)
argument (a maze) and return a function that takes in one (1) argument (a move), and returns the
maze that is the result of moving Player 1 in the given direction.
The rules for moving are
? If a player is immediately blocked by a wall (x) or another player, they do not move
? A player continues to move in a given direction as long as “forward” and “backward” are
their only options to move in
“forward” is in the direction of travel and “backward” is opposite the direction of travel
? If a player encounters an obstacle (a wall or another player) while moving, they will attempt
to change their direction (with priority given to up, down, left, and right in that order), but
will not reverse their direction.
? A player will stop moving once they reach the goal (g), a dead-end where their only option
is to reverse their direction, or when they reach a location where they have more options for
travel than just “forward” and “backward”.

3 One Player, Many Moves
The second part (onePlayerManyMoves in the file csce322homeWork02part02.js) will take in one
(1) argument (a maze) and return a function that takes in one (1) argument (an array of moves),
and returns the maze that is the result of Player 1 making all of the moves. If the maze is solved
before the list of moves is completely processed, the resulting maze is returned.

one (1) argument (a maze) and return a function that takes in one (1) argument (a list of moves),
and returns the maze that is the result of each player making the next move in the list in turn
(starting with Player 1). If the maze has already been solved, the maze is returned in that state.
