栈的应用——Rails

一.题目描述 某城市有一个火车站,有n节车厢从A方向驶入车站,按进站顺序编号为1~n,经中转站C驶向B.中转站C,这是一个可以停放任意多节车厢的车站,但由于末端封顶,驶入C的车厢必须以相反的顺序驶出C.你的任务是判断它能否按某种顺序进入B方向的车站. 二.解题思路 中转站C就相当于一个栈,可以随时入栈和出栈. 三.代码实现 #include<stdio.h> #include<iostream> #include<stack> #include<cstdbool&…

SCSS学习笔记（一）

SCSS的由来 SCSS就是加强版的CSS,要讲SCSS那就一定要从SASS讲起 SASS Sass(英文全称:Syntactically Awesome Stylesheets)是一个最初由Hampton Catlin设计并由Natalie Weizenbaum开发的层叠样式表语言.2007年发行,2016年版本稳定,设计和开发分开进行,让这个语言的功能相当完善. Sass是像CSS一样的层叠样式表语言,但是它并不是由前端社区发明的,而是由Ruby社区发明创造,为什么Ruby社区要为前端创造语…

POJ 1363 Rails(栈)

思路:将出车站的顺序存入数组train,由于入车站的顺序是固定的,为1~N,所以用P表示进站的车,初始为1. 接下来举例说明吧: 原来入站顺序:    1 2 3 4 5 读入的出战顺序: 3 4 2 5 1 按照train数组的顺序来执行, 1.一开始p=1,i=1: p与train[i]=3不相等,将p(1)入栈,p++:再比较不相等,将p(2)入栈,p++: p=train[3],则i++,p++: 2.i=2: 先比较train[i]与栈顶元素2是否相同,不相同,则与p比较. train…

UVa514 Rails (栈)

题意:一列有n节车厢的火车按顺序进站,给你一个出站顺序,问你该火车的车厢能否以该顺序出站? 分析:出站的车厢满足后进先出的关系,所以我们考虑采用栈s 假设车厢一共有n节,n = 5: 进站顺序A:1 2 3 4 5 出站顺序B/target: 2 3 4 5 1 如果进站的车厢没有立马出站,则将该车厢入栈s.push(A++) 判断栈里面车厢的顺序是否和出站顺序一致 s.top()==  target[B] #include<cstdio> #include<stack> usin…
