[Solved] SOLVED:MazeGenerator and MazeTraversal

I 8.20 (Maze Traversal Using Recursive Backtracking) The grid of #s and dots (.) in Fig. 18.22 is a two-dimensional array representation of a maze. The #s represent the walls of the maze, and the dots represent locations in the possible paths through the maze. A move can be made only to a lo cation in the array that contains a dot. Write a recursive method (mazeTraversal) to walk through mazes like the one in Fig. 18.22 The method should receive as arguments a 12-by-12 character array representing (he maze and h current location in the maze (the first time this method is called, the current location should be the entry point of the maze). As mazeTraversal attempts to locate the exit, it should place the character x in each square in the path. Theres a simple algorithm for walking through a maze that guarantees finding the exit (assuming theres an exit). If theres no exit, youll arrive at the starting location again. The algorithm is as follows: From the current location in the maze, try to move one space in any of the possible directions (down, right, L1 or left). If its possible to move in at least one direction, call mazeTraversal recursively, passing the new spot on the maze as the current spot if its not possible to go in any direction, back up to a previous location in the maze and try a new direction for that location (this is an example of recursive bacbracldng). Program the method to display the maze after each move so the user can watch as the maze is solved. The final output of the maze should display only the path needed to solve the mazeif going in a particular direction results in a dead end, the xs going in that direction should not be displayed. [Hint: To display only the final path, it may be helpful to mark off spots that result in a dead end with another character (suchas o).) 18.21 (Generating Mazes RaidomIy) Write a method mazeGenerator that takes as an argument a two-dimensional 12-by-12 character array and randomly produces a maze. The method should also provide the starting and ending locations of the maze. lest your method mazeTraversal from Exercise 18.20, using several randomly generated mazes. 18.22 (Maze.c of Any Size) Generalize methods mazeTraversal and mazeGenerator of Exercise 18.20 and Exercise 18.21 to process mazes of any width and height.
