public class Example Problem {
}
public static int multiplyDigits (int n)
{
}
if (n == 0)
else
return 1;
return ((n % 10) * multiplyDigits (n / 10));
public static void main(String[] args)
{
int num = 44;
int result = multiplyDigits (num);
System.out.println(result);
1) How many arguments/parameters the recursive function takes?
2) Write the base case and briefly explain its logic.
3) Write the recursive function call statement and briefly explain its logic.
4) How many total steps are present for function call of 'num(44)' ?
