力扣leetcode-cn.com/problems/diameter-of-binary-tree/ 题目描述 给定一棵二叉树,你需要计算它的直径长度。一棵二叉树的直径长度是任意两个结点路径长度中的最大值。这条路径可能穿过也可能不穿过根结点。 示例: 给定二叉树 1 / \ 2 3 / \ 4 5 返回3, 它的长度是路径 [4,2,1,3] 或者 [5...
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 thelongestpath between any two nodes in a tree. This path may or may not pass through the root. Example: Given a binary tree 1 / \ 2 3 / \ 4 5 R...

543. Diameter of Binary Tree(二叉树的最长直径) 给定二叉树,您需要计算树直径的长度。二叉树的直径是一棵树中任何两个节点之间的最长路径的长度。此路径可能会也可能不会通过根。 思路: 要计算二叉树的最长直径,肯定需要遍历树,而最长直径肯定有一个相对的root节点,所以可以后序遍历了,每到达一个节点就要计算...
LeetCode 543. Diameter of Binary Tree 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 longest path between any two nodes in a tree. This path may or may n......
Can you solve this real interview question? Diameter of Binary Tree - Given the root of a binary tree, return the length of the diameter of the tree. The diameter of a binary tree is the length of the longest path between any two nodes in a tree. This p
Given the root of a binary tree, return the length of the diameter of the tree. The diameter of a binary tree is the length of the longest path between any two nodes in a tree. This path may or may not pass through the root. The length of a path between two nodes is represented ...
