Web31. mar 2024 · 1 The 'build-heap` method (what you call top-down building) is O (n). So every insertion into the heap would be an O (n) operation. Contrast that to inserting at the bottom and sifting up, which is O (log n) in the worst case, but closer to O (1) in practice. See Argument for O (1) average-case complexity of heap insertion.

WebHeap data structure is a complete binary tree that satisfies the heap property, where any given node is. always greater than its child node/s and the key of the root node is the largest among all other nodes. This property is also called max heap property.; always smaller than the child node/s and the key of the root node is the smallest among all other nodes.
