Two people are playing a game with a string ss, consisting of lowercase latin letters. On a player's turn, he should choose two consecutive equal letters in the string and delete them. For example, if the string is equal to "xaax" than there is…

请用LinkedList模拟栈数据结构的集合,并测试 题目的意思是: 你自己的定义一个集合类,在这个集合类内部可以使用LinkedList模拟. package cn_LinkedList; import java.util.LinkedList; public class MyStack { //定义一个LinkedList类的成员变量 private LinkedList list = null; /** * 构造方法 * @list 调用LinkedList类的方法 */ public M…

一.编写一个酒店管理系统 1.直接上代码 package com.bjpowernode.java_learning; ​ public class D69_1_ { //编写一个程序模拟酒店的管理系统:预定房间.退房....... public static void main(String[] args) { } } class Room{ String no; String type;//“标准间”“双人间”“豪华间” boolean isUse;//true表示占用,false表示空闲…

栈是一种有序列表,可以使用数组的结构来储存栈的数据内容 思路 1. 创建一个栈类StackArray 2. 定义一个top来模拟栈顶,初始化为-1 3. 入栈: 当有数据加入到栈的时候 top++ stack[top] = data 4. 出栈 int value = stack[top]; top--, return value 代码实现 //定义一个类来表示栈 class ArrayStack{ private int maxSize; //栈的大小 private int[] stack;…

Stack is one of the most fundamental data structures, which is based on the principle of Last In First Out (LIFO). The basic operations include Push (inserting an element onto the top position) and Pop (deleting the top element). Now you are supposed…

题意:有一个\(01\)串,两个相邻的\(0\)可以变成一个\(1\),两个相邻的\(1\)可以直接消除,问操作后的字符串. 题解:数组模拟栈直接撸,上代码吧. 代码: class Solution { public: /** * * @param str string字符串 初始字符串 * @return string字符串 */ string solve(string str) { // write code here char stk[1000010]; int cnt=0; for(in…

本篇用双向链表和模拟栈混洗过程两种解答方式具体解答“栈混洗”的应用问题 有关栈混洗的定义和解释在此篇:手记-栈与队列相关 列车调度(Train) 描述 某列车调度站的铁道联接结构如Figure 1所示. 其中,A为入口,B为出口,S为中转盲端.所有铁道均为单轨单向式:列车行驶的方向只能是从A到S,再从S到B:另外,不允许超车.因为车厢可在S中驻留,所以它们从B端驶出的次序,可能与从A端驶入的次序不同.不过S的容量有限,同时驻留的车厢不得超过m节. 设某列车由编号依次为{1, 2, ..., n}…
