WebThe first recursive technique creates one heap by stacking the first n-1 elements in ascending order, and then it moves the nth element to the top of the heap. The second recursive technique begins by constructing two heaps, one for each of the root's subtrees, and then proceeds to move the root further down the heaps. WebThe recursive call HEAPIFY(A, 4) now sets i = 4. After swapping A[4] with A[9], as shown in (c), node 4 is fixed up, and the recursive call HEAPIFY(A, 9) yields no further change to the data... northaw cofe primary school https://1stdivine.com
