102. 二叉树的层序遍历 - 给你二叉树的根节点 root ,返回其节点值的 层序遍历 。 (即逐层地,从左到右访问所有节点)。 示例 1: [https://assets.leetcode.com/uploads/2021/02/19/tree1.jpg] 输入:root = [3,9,20,null,null,15,7] 输出:[[3],[9,20],[15,7]]
http://bangbingsyb.blogspot.com/2014/11/leetcode-balanced-binary-tree.html 我想说明的是,什么 depth of tree and height of tree depth of node n: length of path from n to root. 所以说, depth of subtree 指的应该就是 这棵subtree最大的深度,以该subtree结点为root。
