Exercises with yank and nthcdr

• Using C-h v (describe-variable), look at the value of your kill ring. Add several items to your kill ring; look at its value again. Using M-y (yank-pop), move all the way around the kill ring. How many items were in your kill ring? Find the value of kill-ring-max. Was your kill ring full, or could you have kept more blocks of text within it?
• Using nthcdr and car, construct a series of expressions to return the first, second, third, and fourth elements of a list.
