(3) image the body of the maze is completely filled with walls - you can start at any location with both odd value coordinates as an open location and systematically eliminate wall locations (opening paths), always beginning with an open location and going two squares at a time in any direction to an untouched location provided that location is within the grid when you can no longer eliminate any, you will have a maze where all open locations will be reachable and it will have one path from the starting point to the end point - guaranteed.After modifying the Greenfoot book Ch. In Greenfoot, the Run button repeatedly executes all of the programming statements in the classs act method in sequential order until the pause button is clicked.
