When we add the elements in a heap one by one and keep satisfying the heap property (max heap or min heap) at every step, then the total time complexity will be O(nlogn). Because the general structure of a binary heap is of a complete binary tree. Hence the … See more Often, answers to these questions focus on the difference between siftUp and siftDown. Making the correct choice between siftUp and … See more Both of these solutions will produce a valid heap. Unsurprisingly, the more efficient one is the second operation that uses siftDown.
