WebApr 25, 2024 · binary heaps can be efficiently implemented on top of either dynamic arrays or pointer-based trees, BST only pointer-based trees. So for the heap we can choose the more space efficient array implementation, if we can afford occasional resize latencies. binary heap creation is O (n) worst case, O (n log (n)) for BST.
