Can you solve this real interview question? Maximum Sum BST in Binary Tree - Given a binary tree root, return the maximum sum of all keys of any sub-tree which is also a Binary Search Tree (BST). Assume a BST is defined as follows: * The left subtree
functioninOrderWithoutRecursion(root){if(!root)returnvar parentNode = root var stack =newStack()while(parentNode || !stack.isEmpty()) {// 一直遍历到左子树的最下面,将一路遍历过的节点push进栈中if(parentNode) { stack.push(parentNode) parentNode = parentNode.leftNode }// 当parentNode为空时,说...

二叉树binary tree,则加了“二叉”(binary),意思是在树中作区分。每个节点至多有两个子(child),left child & right child。二叉树在很多例子中使用,比如二叉树表示算术表达式。 如图:1/8是左节点;2/3是右节点; 二、二叉搜索树 BST 顾名思义,二叉树上又加了个搜索的限制。其要求:每个节点比其左子树元素大...
B-tree is a special type of self-balancing search tree in which each node can contain more than one key and can have more than two children. It is a generalized form of thebinary search tree(BST). It is also known as aheight-balanced m-way tree. ...
二分搜索树(Binary Search Tree,简称BST)是一种特殊的树形数据结构,它的左子树上所有节点的值都小于根节点的值,而右子树上所有节点的值都大于根节点的值。二分搜索树在数据查找、插入和删除操作中有着广泛的应用。深度优先遍历(Depth-First Search,简称DFS)是一种用于遍历或搜索树或图的算法。在二分搜索树中,深...
Given a binary tree, find the size of the largest BST (Binary Search Tree) in it. The largest BST in the following binary tree is 3, formed by a subtree rooted at node 15.
二叉查找树(BST:Binary Search Tree),又称二叉排序树是一种特殊的二叉树,它改善了二叉树节点查找的效率。二叉查找树有以下性质: 简单概况:小的放左边,大的放右边 对于任意一个节点 n, 其左子树(left subtree)下的每个后代节点(descendant node)的值都小于节点 n 的值; ...
二叉树也有链式实现和顺序实现两种方式。顺序存储极大的浪费存储空间,除非是完全二叉树或者满二叉树。但是相比于链式结构同时也能够省下申请新节点的时间。而二叉搜索树Binary Search Tree(BST)几乎是最常见的应用,BST有可能是空树,否则它应该满足如下几点要求: ...
