Each operation has its own runtime complexity. Maybe you were thinking of the runtime complexity of heapsort which is a sorting algorithm that uses a heap. In that case, the runtime complexity is O (n*log (n)). Share Improve this answer Follow Building a binary heap will take O(n) time with Heapify(). 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.
