1. Question: 95. Unique Binary Search Trees II Given an integern, generate all structurally unique BST's (binary search trees) that store values 1 ...n. Example: Input: 3 Output: [ [1,null,3,2], [3,2,null,1], [3,1,null,null,2], [2,1,3], [1,null,2,null,3] ] Explan...
Question: C++ problem Part 1: Building Your Binary Search Tree Using the header file provided in class, create a templated Binary Search Tree data structure. Your Binary Search Tree class must contain the following public constructors and destructors: Defau...
Successor is the node which will replace the deleted node. Now the question is to how to find it and where to find it. Successor is the smaller node in the right sub tree of the node to be deleted. Display(): To know about how we are displaying nodes in increasing order, Click Here...

二分搜索（binary search），又称折半搜索（half-interval search）、对数搜索（logarithmic search）、对半搜索（binary chop），是一种在有序数组中查找特定元素的搜索算法。此算法原理简单，从数组中间元素开始，通过比较元素与目标值的大小，不断缩小搜索范围。具体步骤如下：给定有序数组A及其目标值T，...
Question: BINARY SEARCH TREE EASY Suppose a binary search tree property is that each node’s value is a letter of the alphabet, and the comparison between two letters is based on alphabetical order. Recall that the relevant portion of alphabetical order...
二叉搜索树是一种节点值之间具有一定数量级次序的二叉树，对于树中每个节点：示例：观察二叉搜索树结构可知，查询每个节点需要的比较次数为节点深度加一。如深度为 0，节点值为 “6” 的根节点，只需要一次比较即可；深度为 1，节点值为 “3” 的节点，只需要两次比较。即二叉树节点个数确定的情况下，...
Question Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node's key. The right subtree of a node contains only nodes with keys greater than the node...
