104. 二叉树的最大深度 - 给定一个二叉树 root ,返回其最大深度。 二叉树的 最大深度 是指从根节点到最远叶子节点的最长路径上的节点数。 示例 1: [https://assets.leetcode.com/uploads/2020/11/26/tmp-tree.jpg] 输入:root = [3,9,20,null,null,15,7] 输出
地址:https://leetcode-cn.com/problems/maximum-width-of-binary-tree/ 给定一个二叉树,编写一个函数来获取这个树的最大宽度。树的宽度是所有层中的最大宽度。这个二叉树与满二叉树(full binary tree)结构相同,但一些节点为空。 每一层的宽度被定义为两个端点(该层最左和最右的非空节点,两端点间的null节点...
