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 ...
543. 二叉树的直径 Diameter of Binary Tree 题目https://leetcode-cn.com/problems/diameter-of-binary-tree/submissions/ 路径是三选一,左子树->root->右子树、左子树->root->root.parent、右子树->root->root.parent 1、root==NULL 0 2、root-&......
也可以在迭代每一个node的时候,记录下其diameter,ans就是所有node diameter最大值: #Definition for a binary tree node.#class TreeNode(object):#def __init__(self, x):#self.val = x#self.left = None#self.right = NoneclassSolution(object):defdiameterOfBinaryTree(self, root):""":type root:...
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...
