I was asked whether it's ok to use a loop instead of recursion in Lab 3. Before answering I'd like to know what sort of loop you would use. Many loop options are covered in Chapter 9 of the text if you want to look ahead.

Apparently there is a package of code that implements loops. You can import it into Racket. I don't want you to do that unless you have read and can explain how the code works.

That's a good example to look at to review your understanding of recursion. Also, look at the additional hint on the web page.
