Escape a Maze
Let's get some more practice with algorithms by escaping from a maze!
Implement a public class
MazeEscape that provides a single public class method named
escape accepts a single parameter, a
Maze object with methods explained below.
Your goal is to manipulate the maze until you reach the exit, and then return it when you are finished.
If the passed
null, throw an
To navigate the maze, using the following
truewhen you have reached the exit of the maze
turnRight()rotates your character 90 degrees to the right
turnLeft()rotates your character 90 degrees to the left
trueif you can move one cell forward,
falseotherwise. Your path may be blocked by a wall!
move()moves your character one cell forward and increases the step counter
Maze object represents a simply-connected or perfect maze: one that contains no loops. As a result,
we suggest that you pursue a classic maze escape algorithm: wall following. Simply put, in a maze that contains no
loops, as long as you continue following a wall you will eventually reach the exit. In a corn maze, you might
implement this by simply maintaining contact with a wall (right or left) until you complete the maze. However,
you'll need to think a bit about how to implement this algorithm to finish this problem.
