代码很久以前写，不太简洁

因此再贴一个刘汝佳代码

#include<iostream>
#include<cstring>
using namespace std;
const int N=26;
int vis[10][N];
bool flag;
bool sum(int *a)
{
    for(int i=0;i<N;i++)
    if(a[i]) return false;
    return true;
}
int main()
{
    int loop,ans=0,cnt;
    string str;
    while(cin>>loop&&loop>0)
    {
        flag=false;
        memset(vis,0,sizeof(vis));
        cin>>str;
        for(int i=0;i<str.length();i++)
        {
            vis[0][str[i]-‘a‘]=1;
            vis[1][str[i]-‘a‘]=1;
            vis[2][str[i]-‘a‘]=1;
        }
        cin.clear();
        cin>>str;
        cnt=0;

        for(int i=0;i<str.length();i++)
        {
            if(vis[1][str[i]-‘a‘]) vis[1][str[i]-‘a‘]=0;
            if(vis[2][str[i]-‘a‘]==0) cnt++,vis[2][str[i]-‘a‘]=1;
            if(cnt==7) {
                cout<<"Round "<<loop<<endl;
                cout<<"You lose."<<endl;
                flag=1;break;
            }
            if(sum(vis[1])) {
                cout<<"Round "<<loop<<endl;
                cout<<"You win."<<endl;
                flag=1;break;
            }
        }
        if(!flag)
        {
            cout<<"Round "<<loop<<endl;
            cout<<"You chickened out."<<endl;
        }
    }
}
