Here's an algorithm:

1) Find the smallest integer in the list, this is A.
2) Find the largest integer in the list, this is B.
3) Return the range A-B.

One way of doing steps 1 and 2 is to sort the list. Then the smallest 
integer will be the first element and the largest integer will be the last 
element in the list.
