最小深度是指树的根结点到最近叶子结点的最短路径上结点的数量。 Given a binary tree, find its minimum depth.The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. 示例1: 输入: (1,2,3,4,5) 输出:2 代码: 1/**2* struct Tr...
Minimum Depth of Binary Tree 二叉树的最小深度: 给定一个二叉树,找出其最小深度。 最小深度是从根节点到最近叶子节点的最短路径上的节点数量。 解答: 原本如果求二叉树的高度的话,直接求两个子树的高度即可。但此时求二叉树的最小深度的话,应该要求 两个子树当中深度较低的一个,但是需要考虑的特殊情况是子...
public int maxDepth(TreeNode root) { if (root == null) { return 0; } return Math.max(maxDepth(root.left), maxDepth(root.right)) + 1; } 这道题是不是只要把Math.max,改成Math.min就够了。 public int minDepth(TreeNode root) { if (root == null) { return 0; } return Math.min...
【题目】 Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. 【分析】 类似于:LeetCode之Maximum Depth of LeetCode 111. Minimum Depth of Binary Given a binary tree, find its min...
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…
int mright=minDepth(root->right); if(mleft==0) return 1+mright; else if(mright==0) return 1+mleft; else return min(mleft,mright)+1; } }; 二、 * Definition for binary tree * struct TreeNode { * int val; * TreeNode *left; ...
The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. Note:A leaf is a node with no children. Example: Given binary tree[3,9,20,null,null,15,7], 3 / \ 9 20
class TreeNode { public int val; public TreeNode left, right; public TreeNode(int x) { val = x; left = null; right = null; } } C# Copy The code is a C# function that returns the minimum depth of a binary tree. The depth of a tree is the number of nodes along the longest ...
