题目大意】两人玩牌,每次比较第一张牌的大小,放到底部,问最后谁赢,如果一直循环,则输出-1

解题思路】设置两个队列,按照题目意思模拟一下即可,注意在循环一定次数下仍然没有结果,则无解

代码:

<span style="font-family:SimSun;font-size:14px;">#include <bits/stdc++.h>
using namespace std;
const int N=1e6;
queue <int>va,vb;
int main()
{
    int t,a,b,n,m;
    scanf("%d",&t);
    scanf("%d",&n);
    for(int i=0; i<n; i++)
    {
        scanf("%d",&a);
        va.push(a);
    }
    scanf("%d",&m);
    for(int i=0; i<m; i++)
    {
        scanf("%d",&b);
        vb.push(b);
    }
    int s=0;
    while(!va.empty()&&!vb.empty())
    {
        s++;
        if(s>N) break;
        int vah=va.front();
        int vbh=vb.front();
        va.pop();
        vb.pop();
        if(vah<vbh)
        {
            vb.push(vah);
            vb.push(vbh);
        }
        if(vah>vbh)
        {
            va.push(vbh);
            va.push(vah);
        }
    }
    if(va.empty()||vb.empty())
    {
        if(va.empty())
        {
            printf("%d 2\n",s);
        }
        else printf("%d 1\n",s);
    }
    else puts("-1");
    return 0;
