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-...
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...
For a binary tree to be a binary search tree, the data of all the nodes in the left sub-tree of the root node should be≤the data of the root. The data of all the nodes in the right subtree of the root node should be>the data of the root. ...

【浅谈数据结构】《数据结构》Data Structure 《数据结构》60’ 一、栈(stack)、队列(Queue)、向量(Vector) 1、链表 带哨兵节点链表了解清楚 链表要会写,会分析。各种链表。 2、栈 LIFO(last in first out)先存进去的数据,最后被取出来,进出顺序逆序。即先进后出,后进先出。
The basic purpose and idea behind such a data structure are to have a storing mechanism that provides a way for efficient sorting, searching, traversing, insertion and deletion operations. Working of Binary Search Tree: The Binary search tree works in a manner where every element that is to be...

Non-Linear Data Structure Elements are arranged in one-many, many-one and many-many dimensions Example: tree, graph, table, etc. 数据结构的种类: 线性数据结构 元素在一个维度之内排列,这个维度也叫做线性维度 例子:列表,栈,队列,等等 非线性数据结构 ...
