1. In your own words, compare the design of the iterative method with the design of the recursive method. What equivalent things are happening and where do they happen in each solution?
2. Why did the iterative version of your Applet produce the same drawing with a Stack and also with a Queue?
3. Explain what did happen differently when you used a Queue instead of a Stack.
4. Did you introduce any kind of delays? If so, what did you observe for recursive vs. iterative and stack vs. queue?
