template <typename T>                   //LINE-1
 
double product(T num){  return num; }    //LINE-2
 
template <typename T, typename... Tail>         //LINE-3
 
double product(T num, Tail... nums){ 
 
    return num * product(nums...);         //LINE-4
}

int main(){
    int a, b, c;
    double d, e, f;
    std::cin >> a >> b >> c;
    std::cin >> d >> e >> f;
