题目大意: 给你一个n 代表有n列 火车,  第一个给你的一个字符串 代表即将进入到轨道上火车的编号顺序, 第二个字符串代表的是 火车出来之后到顺序, 分析一下就知道这,这个问题就是栈, 先进后出吗, 就是问你这个编号有没有可能出现, 有可能的话输出顺序,没可能直接输出No 题目分析: 我们用栈进行模拟, 先判断是否有这种出栈的可能, 假如有这种可能的话我们在模拟 一遍出栈的顺就行了. 每一次有新元素入栈我们就判断他是否雨 第二个字符串的第一个元素是否相等, 假如一样, 就让次元素出栈. 代码…

题目大意:有n辆火车,按一定的顺序进站(第一个字符串顺序),问是否能按规定的顺序出站(按第二个字符串的顺序出去),如果能输出每辆火车进出站的过程. 题目思路:栈的特点是先进后出,和题意类似,还有有一种情况是:开进来立马有开出去.并用vis[]数组的0,1标记进出站情况. 具体看代码 #include<cstdio> #include<cstring> #include<cmath> #include<queue> #include<algorithm&…

火车进站,模拟一个栈的操作,额外的栈操作,查看能否依照规定顺序出栈. 数据量非常少,故此题目非常easyAC. 直接使用数组模拟就好. #include <stdio.h> const int MAX_N = 10; char inOrder[MAX_N], outOrder[MAX_N], stk[MAX_N]; bool rs[MAX_N<<2]; int n; int main() { while (scanf("%d", &n) != EOF)…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1022 题目大意: 车的进出站问题,先给出N个火车,再按序列一的方式进站,判断能否以序列二的方式出站,若能先输出"Yes.",再输出出站步骤,以FINISH结束,若不能,输出"No.",仍以FINISH结束. 思路: 直接模拟栈,注意细节! #include<iostream> #include<cstdio> #include<cstrin…

这道题是道简单的栈模拟题,只要按照真实情况用栈进行模拟即可: #include<stdio.h> #include<string.h> #include<stack> using namespace std; int main() { ]; ], s2[]; stack <char> s; while(~scanf("%d %s%s",&n,s1,s2)) { while(!s.empty()) s.pop(); //也可以不写这…
