示例1: primeCount

if(lst.empty()){ //base case
return 0; //empty list has no (prime) numbers
}
if(isPrime(lst.front())){ //check if first item is prime
cout << lst.front() << endl;
lst.pop_front(); //can do this bc lst is passed by value
return 1 + primeCount(lst); //recursive call
}
else{ //first number isnt prime
lst.pop_front(); //dont output, just delete it
return primeCount(lst); //dont add 1 to primecount
}
