C++数据结构二叉搜索树的实现应用与分析

[LeetCode] 108.Convert Sorted Array to Binary Search Tree 将有序数组转为二叉搜索树 Given an array where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in wh

[LeetCode] 96. Unique Binary Search Trees 独一无二的二叉搜索树 Given n, how many structurally unique BST's (binary search trees) that store values 1 ... n? Example: Input: 3 Output: 5 Explanation: Given n = 3, there are a total of 5 unique BST's: 1         3  

[LeetCode] 98. Validate Binary Search Tree 验证二叉搜索树 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 ri

[LeetCode] 173.Binary Search Tree Iterator 二叉搜索树迭代器 Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST. Calling next() will return the next smallest number in the BST. Note: next() and

废话不多说了,直接给大家贴代码了,具体代码如下所示: class BST { public: struct Node { int key;//节点的key int value;//节点的value Node* left; Node *right; int N;//节点的叶子节点数目 Node(int _key, int _value, int _N) { key = _key; value = _value; N = _N; } }; BST(); ~BST(); void put(int ke

[LeetCode] 99. Recover Binary Search Tree 复原二叉搜索树 Two elements of a binary search tree (BST) are swapped by mistake. Recover the tree without changing its structure. Example 1: Input: [1,3,null,null,2]    1 / 3 \ 2 Output: [3,1,null,null,2]    3 / 1

[LeetCode] 109.Convert Sorted List to Binary Search Tree 将有序链表转为二叉搜索树 Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary

[LeetCode] 95. Unique Binary Search Trees II 独一无二的二叉搜索树之二 Given an integer n, 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],

目录 概念 二叉搜索树的实现

本文实例讲述了javascript二叉搜索树实现方法.分享给大家供大家参考,具体如下: 二叉搜索树:顾名思义,树上每个节点最多只有二根分叉:而且左分叉节点的值 < 右分叉节点的值 . 特点:插入节点.找最大/最小节点.节点值排序 非常方便 二叉搜索树-javascript实现 <script type="text/javascript"> // <![CDATA[ //打印输出 function println(msg) { document.write(msg

本文实例讲述了Python二叉搜索树与双向链表实现方法.分享给大家供大家参考,具体如下: # encoding=utf8 ''' 题目:输入一棵二叉搜索树,将该二叉搜索树转换成一个排序的双向链表. 要求不能创建任何新的结点,只能调整树中结点指针的指向. ''' class BinaryTreeNode(): def __init__(self, value, left = None, right = None): self.value = value self.left = left self.

什么是二叉树 二叉树就是树的每个节点最多只能有两个子节点 什么是二叉搜索树 二叉搜索树在二叉树的基础上,多了一个条件,就是二叉树在插入值时,若插入值比当前节点小,就插入到左节点,否则插入到右节点:若插入过程中,左节点或右节点已经存在,那么继续按如上规则比较,直到遇到一个新的节点. 二叉搜索树的特性 二叉搜索树由于其独特的数据结构,使得其无论在增删,还是查找,时间复杂度都是O(h),h为二叉树的高度.因此二叉树应该尽量的矮,即左右节点尽量平衡. 二叉搜索树的构造 要构造二叉搜索树,首先要构造二叉树
