double find(int total, int n) {
     int number, score,  average;
     scanf(”%d”, &number);
     if(number != 0) {
         scanf(”%d”, &score);
         average = find(total+score, n+1);
         if(score >= average)
              printf(”%d:%d\n”, number, score);
         return average;
     } else {
         printf(”Average=%d\n”, total/n);
         return total/n;
     }
}
int main(int argc, char* argv[]) {
     find(0, 0);
}
