Land of Lisp

What You've Learned

In this chapter, we’ve used graph utilities with Lisp to make a more sophisticated game. Along the way, you learned the following:

• The loop function allows us to loop across various types of data. It will be discussed in more detail in Chapter 10.

• The set-difference function tells you which items are in one list but not in another list.

• The intersection function tells you which items are shared by lists.

• The remove-duplicates function removes duplicate items from a list.
