Hi! I'm really lost on the Practice Makes Perfect exercises. They are quite nerve-wrecking. Could anyone suggest what to practice before doing these or help me out? I'm on 'reverse'... Thanks.
One approach is to think of a way to iterate backwards through a list. Can you come up with any ideas?
Another approach might be to iterate the list (the string in this case) and insert each character to the front of a new string. Can you think of how this might be done?
