A binary tree is a tree where each node may only have up to two children. These children are stored on theleftandrightproperties of each node. When traversing a binary tree, we have three common traversal algorithms: in order, pre-order, and post-order. In this lesson, we write each o...

For this problem, a height-balanced binary tree is defined as: a binary tree in which the depth of the two subtrees ofeverynode never differ by more than 1. Example 1: Given the following tree[3,9,20,null,null,15,7]: 代码语言:javascript ...
A binary tree is a tree data structure in which each parent node can have at most two children. Also, you will find working examples of binary tree in C, C++, Java and Python.

二叉树的后序遍历(Binary Tree Postorder Traversal) lintcode:题号——68,难度——easy 2 描述 给出一棵二叉树,返回其节点值的后序遍历。 名词: 遍历 按照一定的顺序对树中所有节点进行访问的过程叫做树的遍历。 后序遍历 在二叉树中,首先遍历左子树,然后遍历右子树,最后访问根结点,在遍历左右...
