　　题目具体描述见：https://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&page=show_problem&problem=430

C++11代码如下：

 #include<iostream>
 #include<string.h>
 using namespace std;
 char ans[], test[];

 int main() {
     int rnd;
     while ((cin>>rnd>>ans>>test)&&rnd!=-) {
         cout << "Round " << rnd << endl;
         int chance = ;
         int left_ch = strlen(ans);
         for (int i = ; i < strlen(test); i++) {
             bool bad = true;
             for (int j = ; j < strlen(ans); j++) {
                 if (ans[j] == test[i]) {
                     ans[j] = ' ';
                     left_ch--;
                     bad=false;
                 }
             }
             if (bad) --chance;
             if (!(left_ch && chance)) break;
         }
         if (!left_ch) cout << "You win."<<endl;
         else if (!chance) cout << "You lose."<<endl;
         else cout << "You chickened out."<<endl;
     }
     return ;
 }
