Shift-up: Move a node up in the tree, as long as needed (depending on the heap condition: min-heap or max-heap) Shift-down: Move a node down in the tree, similar to Shift-up 二叉堆(Binary heap) Abinary heapis a heap data structure created using a binary tree. It can be seen ...

A binary heap is a heap data structure created using a binary tree. It can be seen as a binary tree with two additional constraints: Shape property: A binary heap is a complete binary tree; that is, all levels of the tree, except possibly the last one (deepest) are fully filled, and...

A binary heap is acomplete binary treearranged in heap ordering property. There are two types of ordering: 1. min-heap The value of each node >= the value of its parent. Root is minimum-value element. 2. max-heap The value of each node <= the value of its parent. Root is maximum...
Approximately half of the nodes in the heap will be on the bottom level, because such is the structure of a complete binary tree; they will therefore not be swapped down at all. Then approximately one fourth of the nodes will be on the second level from the bottom, and will be swapped...

Binary Tree Heap 1. Overview Heap is a special type of balanced binary tree data structure. A very common operation on a heap is heapify, which rearranges a heap in order to maintain its property. In this tutorial, we’ll discuss a variant of the heapify operation: max-heapify. We’ll...
