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…

题目链接:http://poj.org/problem?id=1363 题意:有一列火车,车厢编号为1-n,从A方向进站,向B方向出站.现在进站顺序确定,给出一个出站的顺序,判断出站顺序是否合理. 实际上是模拟栈的过程,而栈的特点是先进后出.另外一个麻烦的地方就是输入输出格式问题. 本题实现提供两种方法:没有用到STL栈和有用到STL栈 #include <iostream> // 法二:头文件多包含一个 #include <stack> using namespace std;…
