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...

5. 二叉搜索树不仅支持搜索操作,还支持查找最小值、最大值、后继节点( successor )、前驱节点( predecessor ) 搜索,通过递归能轻易实现搜索操作. TREE-SEARCH(X)ifx == NIL or k ==x.key return xifk <x.key return TREE-SEARCH(x.left)elsereturn TREE-SEARCH(x.right) 迭代版代码如下 ITERATIVE-TREE-...

Binary search tree is a data structure that quickly allows us to maintain a sorted list of numbers. It is called a binary tree because each tree node has a maximum of two children. It is called a search tree because it can be used to search for the presence of a number inO(log(n)...
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。

In computer science, 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: The left subtree of a node contains only nodes with keys less than the node's key. ...
left.search(e, isMulti, cmp) } //n中承载元素等于e,直接返回结果 return n.num } 使用示例 package main import ( "fmt" "github.com/hlccd/goSTL/data_structure/bsTree" "sync" ) func main() { bs := bsTree.New(true) wg := sync.WaitGroup{} for i := 0; i < 10; i++ { wg...
