https://leetcode.com/problems/maximum-depth-of-binary-tree/ 题目: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 思路: 递归左右子树高度 算法: public int maxDepth(TreeNode ro...
LeetCode 111 题,Minimum Depth of Binary Tree 解题思路 1、读题,求解二叉树的最小Depth。 2、用bfs 去解决,队列带上每层的层数。当有一个节点的左右子树都为空时,返回当前层数,就找到解。 Python 代码 # De…
Leetcode:minimum_depth_of_binary_tree解决问题的方法,一、称号并寻求最深的二元相似。给定的二进制树。求其最小深度。最小深度是沿从根节点,到叶节点最短的路径。二、分析当我看到这个题目时。我直接将最深二叉树的代码略微改了下,把max改成min。本以为应该没有问题,
题目:找出二叉树的最大深度 Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Note: A leaf is a node with no children. ...
