Use the same approach from the following website (https://www.raywenderlich.com/4946/introduction-to-a-pathfinding) and as illustrated in the class to show how the cat Moody can use the A* algorithm to get to the bone. Use the same approach to show the results of each step, including the open and closed list (you can use different colors of lists and pictures to show intermediate steps), as well as the use of arrows to indicate the movement direction to get to a square. Use also the same movement cost and heuristic computation approach. When choosing elements from the open list to process, if there are multiple elements with the same scores, choose the element that was most recently added to the list.
