// precondition: n >= 0 and n <= 20
public static long factorial(long n) {
if (n < 0) throw new RuntimeException("Underflow error in factorial");
else if (n > 20) throw new RuntimeException("Overflow error in factorial");
else if (n == 0) return 1;
else return n * factorial(n-1);
}

public static void main(String[] args) {
