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)…

题意:给我们两个序列,看能否通过压栈,出栈将第一个序列转换成第二个. 思路:将序列 1 依次压栈,同时看是否和序列 2 当前元素相同 代码如下: #include<iostream> #include<stack> #define max 100 using namespace std; int main() { stack<char>s; int n,i,j,k,result[max]; char str1[max],str2[max]; while(cin>&…

#include<stdio.h> int main() { int n,i,j,k; ],]; ]; while(scanf("%d %s %s",&n,in,out)!=EOF) { ];//stack维持着正常的进出栈 ;//栈顶 i=j=k=; &&i<n) { if(top!=-1&&stack[top]==out[i]) { top--; flag[k]=; k++; i++; } else { top++; fla…

题意: 给出一个数字n,假设火车从1~n的顺序分别进站,求有多少种出站序列. 思路: 卡特兰数的经典例子.n<101,用递推式解决.需要使用到大数.n=100时大概有200位以下. #include <bits/stdc++.h> using namespace std; ; vector<string> vect; void _mult(string num1, string num2, string &result ) { reverse(num1.begin()…

题意: 给出两个串,串中的数字i 代表编号为i的火车进入车站的顺序,车站如桟一样,先进后出.第二个串是火车出站的顺序,问若按照第一个串那样进站,是否有可能如第二个串一样的出站顺序?火车顶多9辆,即1-9. 思路: 用桟模拟,每进入一辆火车就加到桟顶,判断第二个串中开头是否是此车,若是,两者都删掉,若不是,继续添加火车进桟,继续判断.直到判断匹配了,将桟顶出桟,串头删除,继续匹配桟顶和串头,直到不匹配了,继续进桟.这样一直反复,直到最后,桟中一定为空,第二个串也一定为空.以此判断是否符合条件. #…

一个出栈有多少种顺序的问题.一般都知道是Catalan数了. 问题是这个Catalan数非常大,故此须要使用高精度计算. 并且打表会速度快非常多.打表公式要熟记: Catalan数公式 Cn=C(2n,n) / (n+1); 递推公式 C(n ) = C(n-1)*(4*n-2) / (n+1) 高精度乘以一个整数和高精度除以一个整数的知识.这样还是使用整数数组比較好计算,假设使用string那么就不太好计算了,由于整数也可能是多位的. const int MAX_N = 101; short…
