WebCHAPTER 7: HEAPSORT. In this chapter, we introduce another sorting algorithm. Like merge sort, but unlike insertion sort, heapsort's running time is O(n lg n).Like insertion sort, but unlike merge sort, heapsort sorts in place: only a constant number of array elements are stored outside the input array at any time. WebHeapsort is a much more efficient version of selection sort. It also works by determining the largest (or smallest) element of the list, placing that at the end (or beginning) of the list, then continuing with the rest of the list, but accomplishes this task efficiently by using a data structure called a heap , a special type of binary tree .
