WebFigure 7.4 shows an example of the operation of heapsort after the heap is initially built. Each heap is shown at the beginning of an iteration of the for loop in line 2. The HEAPSORT procedure takes time O(n lg n), since the call to BUILD-HEAP takes time O(n) and each of the n - 1 calls to HEAPIFY takes time O(lg n). Figure 7.4 The operation ... Web26 de mar. de 2024 · Heap sort makes use of max-heap or min-heap to sort the array. The first step in heap sort is to build a min or max heap from the array data and then delete the root element recursively and heapify the heap until there is only one node present in the heap.
