Think back to second year of college, when you took that Algorithms course.

A good sort such as quick sort is O( N logN ), poor ones such as bubble sort are O( N^2 ). A max() function requires a single pass through the list, and so is O( N ). It would be silly to do N log N - N ( i.e. N (log N - 1) ) operations more than you need to.
