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...

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.

Given a binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The path does not need to go through the root. ...
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...
