For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. 这道题根节点和儿子节点的关系理解: 算法视频QQ_1603159172 1.左子树是平衡的 2.右子数是平衡的 3.左右高度差≤1 divide and conquer...
The idea is to traverse the tree in apostorder fashionand calculate the height of the left and right subtree. The height of a subtree rooted at any node will be one more than the maximum height of its left and right subtree. Recursively apply this property to all tree nodes in a bottom...
AVL tree: a balanced binary tree where the heights of the two subtrees rooted at a node differ from each other by at most one. The structure is named for the inventors, Adelson-Velskii and Landis (1962). Height-balanced tree: a tree whose subtrees differ in height by no more than one...
A perfect binary tree of height h has 2h + 1 –1 node. A perfect binary tree with n nodes has height log(n + 1) – 1 = Θ(ln(n)). A perfect binary tree of height h has 2h leaf nodes. The average depth of a node in a perfect binary tree is Θ(ln(n))....

Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. 解题思路: 先明白最小路径的定义:从根结点到最近叶子结点的所包含的结点个数(包括根)。 举个例子: Example1: 代码语言:javascript 代码...
