I'm assuming we started with an ordered BST. If not, then sort the list. If you want a max-heap instead of a min-heap, then reverse the list at this point, too. WebFor this approach, we will first copy the elements of the min-heap array to a soon-to-be-max-heap array using a for-loop. After copying each element to the max-heap array, we will heapify it to move it to its correct position. Following is the procedure for heapifying: 1. For every index in the heap, find its left child and right child. tabletop turkey decorations
