Chapter 8 Project 2 - Reversal (Alice Progamming)


2. Reversal In the world below, the row of skeletons (Graveyard folder on the web gallery) are guarding the gate. Every so often in this world, the row of skeletons is to reverse order. This project is to animate the skeleton chain reversal using structural recursion. The storyboard goes something like the following: Reverse method: If the row of Skeletons is not yet reversed is more than one then Reverse the row of Skeletons starting with the 2nd Skeleton (by recursively calling Reverse Move the Head Skeleton to the end of the list The base case is when there is just one Skeleton in the row (that has not yet been reversed). Of course, a row of 1 Skeleton is already reversed! The recursive case (for n Skeletons, where n is larger than 1) says to first reverse the last n-1 Skeletons, and then move the first Skeleton to the end of the list. Implement the Skeleton reversal storyboard given above. Attachments
