Or, do what Eric says in the … Webbexample of an iterative algorithm, called “selection sort.” In Section 2.5 we shall prove by induction that this algorithm does indeed sort, and we shall analyze its running time in Section 3.6. In Section 2.8, we shall show how recursion can help us devise a more efficient sorting algorithm using a technique called “divide and conquer.”

Again n log b a is n 2, and f(n) is thus Θ(n 2), so Case 2 applies. Thus T(n) is Θ(n 2 log …
