题目 Sample Input: 5 7 5 1 2 3 4 5 6 7 3 2 1 7 5 6 4 7 6 5 4 3 2 1 5 6 4 3 7 2 1 1 7 6 5 4 3 2 Sample Output: YES NO NO YES NO 基本思路 先把输入的数列用数组保存,然后依次将1,2,3...N入栈,每次入栈判断栈顶是否与数组中当前要输出的元素相等,如果相等则出栈(循环).如果遇到栈满或无法输出数组所有元素的情况则输出No. 代码 #include <iostream> #i…

一.线性结构和非线性结构 线性结构: 1)线性绪构作为最常用的数据结构,其特点是数据元素之间存在一对一的线性关系 2)线性结构有两种不同的存储结构,即顺序存储结构和链式存储结构.顺序存储的线性表称为顺序表,顺序表中的存储元素是连续的3)链式存储的线性表称为链表,链表中的存储元素不一定是连续的,元素节点中存放数据元素以及相邻元素的地址信息4)线性结构常见的有:数组.队列.链表和栈,后面我们会详细讲解. 非线性结构: 非线性结构包括:二维数组,多维数组,广义表,树结构,图结构 二.稀疏数组 基本介绍…

线性结构的定义:若结构是非空有限集,则有且仅有一个开始结点和一个终端结点,并且所有结点都最多只有一个直接前驱和一个直接后继. 线性结构的特点: 只有一个首结点和尾结点 除首尾结点外,其他结点只有一个直接前驱和一个直接后继 简言之,线性结构反映结点间的逻辑关系是一对一  的 线性结构包括: 线性表.堆栈.队列.字符串.数组等等,其中,最典型.最常用的是线性表 线性表的基本操作 1.  初始化线性表L  InitList(&L) 2.  销毁线性表L  DestoryList(&L) 3. …

一.数据结构 数据结构由数据和结构两部分组成,就是将数据按照一定的结构组合起来,这样不同的组合方式有不同的效率,可根据需求选择不同的结构应用在相应在场景.数据结构大致 分为两类:线性结构(如数组,链表,队列,栈等),非线性结构(如树,图,表等).本文介绍下线性结构,下章介绍非线性结构. 二.数组 数组表示一组有限个相同类型的数据的集合,顺序存储,下标从0开始,其特点是可以根据下标快速的查找到元素,但在增加和删除元素时会导致大量的数据位置的变动,即这 种情况下性能不高,故数组一般多用于查找频繁,增…

我们知道,在内存中的空间都是连续的.也就是说,0x00000001下面的地址必然是0x00000002.所以,空间上是不会出现地址的突变的.那什么数据结构类型是连续内部空间呢,其实就是数组,当然也可以是堆.数组有很多优势,它可以在一段连续空间内保存相同类型的数据,并且对这些数据进行管理.所以从这个意义上说,掌握了数组才能说明你数据结构入门了. 那么,在实际开发中,我们对线性结构应该注意些什么呢?我个人的观点: (1)数组的资源是有限的,必须确定资源的范围 (2)数组中资源的申请和释放必须一一对应…

前言 当树形结构的层级越来越深时,操作某一节点会变得越来越费劲,维护成本不断增加.所以线性结构与树形的相互转换变得异常重要! 首先,我们约定树形结构如下: node = { id: number, // 数值 parentId: number, // 数值 name: string, children: [] || null, // 用数组的方式保存子节点,适合更多业务场景 }   线性结构: list = [ { id: number, parentId: number, name: stri…

说到线性结构,我们应该立马能够在脑子里蹦出"Array数组"这个词.在Java当中,数组和对象区别基本数据类型存放在堆当中.它是一连串同类型数据存放的一个整体.通常我们定义的方式为: Object[] objs = new Object[n] //n为数组大小 而顺序表的底层便是数组.在Java当中顺序表比较常用的有:ArrayList.Vector等.下面我们通过代码实现我们自己的SequenceList. 首先定义List接口: package com.chen.arithmeti…

线性结构是什么? 线性结构是一种数据结构,它有一对一的关系,就像一个长对,一个接一个,特点是,除第一个元素和最后一个元素外,其它元素前后只有一个元素. 简单示例1: static void Main(string[] args) { //使用BCL中的List线性表 List<string> strList = new List<string>(); strList.Add("123"); strList.Add("456"); strLis…
