C-5.1 Consider a modification of the selection-sort algorithm where instead of finding the smallest element in the unsorted part of the array and swapping it to be in its proper place, as given in Algorithm 5.3, we instead perform a sequence of swaps to move the smallest element to its proper location, as shown in Algorithm 5.20 Show that this algorithm, which is known as bubble-sort, runs in e(n2) time. Algorithm BubbleSort(A): Input: An array A of n comparable elements, indexed from 1 to n Output: An ordering of A so that its elements are in nondecreasing order. fori1 to n 1 do // Move the smallest element in Ai1.. n to Ai by swaps for j n down toi+1 do if Alj -1> Aljl then Swap Aj 1 and A] return A Algorithm 5.20: The bubble-sort algorithm
