LeetCode: Maximum Depth of Binary Tree 题目如下: 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. 即求二叉树的(最大)深度。 有两种思路: 一是使用递归, 二是使用二叉树层序遍历。
题目描述 求给定二叉树的最大深度, 最大深度是指树的根结点到最远叶子结点的最长路径上结点的数量。 Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longe

The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Show Tags Have you met this question in a real interview? Discuss 这道题和Minimum Depth of Binary Tree类似,仅仅只是这个是求最大深度的。解法也和Minimum Depth of Binary Tree一...
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. Example: Given binary tree [3,9,20,null,null,15,7], ...
return its depth = 3. 题目大意 要求输出一棵树的最大高度。 解题思路 这一题递归遍历就可,遍历根节点的左孩子的高度和根节点右孩子的高度,取出两者的最大值再加一即为总高度。 参考代码 packageleetcodeimport("/halfrost/LeetCode-Go/structures")// TreeNode definetypeTreeNode=structures.TreeNode/** ...
Given a n-ary 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. Nary-Tree input serialization is represented in their level order traversal, each group of children is separated by the null value...
