The maximum width of a tree is the maximum width among all levels. The width of one level is defined as the length between the end-nodes (the leftmost and rightmost non-null nodes), where the null nodes between the end-nodes that would be present in a complete binary tree extending down...
原题链接在这里:https://leetcode.com/problems/maximum-width-of-binary-tree/ 题目: Given a binary tree, write a function to get the maximum width of the given tree. The width of a tree is the maximum width among all levels. The binary tree has the same structure as a full binary tree...

Given a binary tree, write a function to get the maximum width of the given tree. The width of a tree is the maximum width among all levels. The binary tree has the same structure as afull binary tree, but some nodes are null. ...
Leetcode 94 Binary Tree Inorder Traversal binarynodesreturntraversaltree Given a binary tree, return the inorder traversal of its nodes' values. For example: Given binary tree [1,null,2,3], 1 \ 2 / 3 return [1,3,2]. 二叉树中序遍历。 先贴一个递归的做法, /** * Definition for a ...
662. Maximum Width of Binary Tree Difficulty: Medium Given a binary tree, write a function to get the maximum width of the given tree. The width of a tree is the maximum width among all levels. The binary tree has the same structure as a full binary tree, but some nodes are null. ...
Leetcode 543. Diameter of Binary Tree 题目描述:找出二叉树的最长直径(也就是所以节点连成最长的路径长度) 题目链接:Leetcode 543. Diameter of Binary Tree 题目思路:用到的就是经典的递归返回值的形式,不断返回左子树和右子树的深度,然后过程中更新最长的路径。 代码如下 参考链接 543. Diameter of Binary Tr...
