Given a binary tree, you need to compute the length of the diameter of the tree. The diameter of a binary tree is the length of the longestpath between any two nodes in a tree. This path may or may not pass through the root. Example:Given a binary tr…

二叉树天然的递归特性,使得我们可以使用递归算法对二叉树进行遍历和重建.之前已经写过LeetCode二叉树的前序.中序.后序遍历(递归实现),那么本文将进行二叉树的重建,经过对比,会发现二者有着许多相似之处. 准备工作 二叉树节点定义: //Definition for a binary tree node. public class TreeNode { int val; TreeNode left; TreeNode right; TreeNode(int x) { val = x; } }…
