Unfortunately the section on runtime complexity has a mistake.

Constant runtime is O(1) ... O(n) is linear runtime. Summing the elements of an array would be linear, since you have to access each element of the array one time.

Great catch, I made the update right away! The add function given would run in O(1) time, not O(n) time.
