Leetcode98.Validate_Binary_Search_Tree 对于二叉搜索树的任意一个节点,其值应满足:向上回溯,第一个向左的节点,是其下界;第一个向右的结点,是其上界。 例如: 从‘14’向上回溯,第一个向左的结点是‘13’,第一个向右的结点是‘14’,所以‘14’的位置正确。 那么,我们反过来,从上向下看,就有:左儿子的父...

2二叉排序树(binary search tree) 之前我们遇到的 vector list queue 这都是线性结构。 也就是从头到尾,逻辑上一个挨着一个的结构。 这种结构最大的缺点就是元素数量变的很多之后,就像一个很长的绳子,或者钢筋,中间插入元素和删除元素都非常的费劲。

A binary search tree is a tree-like data structure where each node represents a token. The tree follows two simple rules:All nodes in the left subtree of a node contain values smaller than the node’s value. All nodes in the right subtree of a node contain values larger than the node...
This is a Java Program to implement Binary Search Tree. A binary search tree (BST), sometimes also called an ordered or sorted binary tree, is a node-based binary tree data structure which has the following properties: i) The left subtree of a node contains only nodes with keys less ...
