Given a non-empty binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some ...
题目: Binary Tree Maximum Path Sum Given a binary tree, find the maximum path sum. The path may start and end at any node in the tree. For example:Given the below binary tree, Return . 节点可能为负数,寻找一条最路径使得 ...

问题 给出一个二叉树,找到其中的最大路径和。 路径可以从树中任意一个节点开始和结束。 例如: 给出如下二叉树, 1 / \ 2 3 返回6。 初始思路 为了简化分析,我们先假设二叉树中所有节点的值都是正数。通过观察可以发现,一棵 ...
Given an integer array with no duplicates. A maximum tree building on this array is defined as follow: The root is the maximum number ...
们一个二叉树,让我们返回所有根到叶节点的路径,跟之前那道Path Sum II很类似,比那道稍微简单一些, ...
Given a binary tree and a sum, determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given ...
If the depth of a tree is smaller than 5, then this tree can be represented by a list of three-digits integers. For each integer in this list ...
二叉树的深度的概念最值得注意的地方,在于 到"叶子"节点的距离。 一般来说,如果直接说“深度”,都是指最大深度,即最远叶子的距离。 这里放两道例题,最小深度和最大深度。 1. 二叉树的最小深度 Given a binary tree, find its minimum depth. ...
在写这篇文章之前说一下数据结构和算法这个系列,这个系列包含了很多东西,比如啥子排序,线性表,广义表,树,图这些大家都是知道的,但是这些东西我们学了之后工作中能用到的又有多少呢,据我所知绝大部分公司,一线码农,屌丝,程序猿是用不到这些东西,既然这样为啥子我还要强调这个系列呢,本人觉得算法和数 ...
