二叉搜索树(BST,Binary Search Tree),也称二叉排序树或二叉查找树. 二叉搜索树:一棵二叉树,可以为空:如果不为空,满足以下性质: 非空左子树的所有键值小于其根结点的键值: 非空右子树的所有键值大于其根结点的键值: 左右子树都是二叉搜索树: Wiki中的定义: The left subtree of a node contains only nodes with keys less than the node's key. The right subtree of a nod…
You need to construct a string consists of parenthesis and integers from a binary tree with the preorder traversing way. The null node needs to be represented by empty parenthesis pair "()". And you need to omit all the empty parenthesis pairs t…
1053 Path of Equal Weight(30 分) Given a non-empty tree with root R, and with weight Wi assigned to each tree node Ti. The weight of a path from R to L is defined to be the sum of the weights of all the nodes along the path from R to any leaf no…
1110 Complete Binary Tree (25 分) Given a tree, you are supposed to tell if it is a complete binary tree. Input Specification: Each input file contains one test case. For each case, the first line gives a positive integer N (≤20) which is the total nu…
翻译 给定一个二叉树,返回从下往上遍历经过的每一个节点的值. 从左往右,从叶子到节点. 比如: 给定的二叉树是 {3,9,20,#,#,15,7}, 3 / \ 9 20 / \ 15 7 返回它从下往上的遍历结果: [ [15,7], [9,20], [3] ] 原文 Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, lev…
[104-Maximum Depth of Binary Tree(二叉树的最大深度)] [LeetCode-面试算法经典-Java实现][全部题目文件夹索引] 原题 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. 题目大意 给…
