Recursion - digits in reverse order

Question

I need to implement a recursive method printDigits that takes an integer num as a parameter and prints its digits in reverse order, one digit per line.

This is what

Answer 1

I came looking for a more elegant version than mine, but perhaps this just requires a bit of a messy algorithm. Mine also returns the actual integer value which I agree is much more useful than only printing the string: Mine:

public static int reverse(int n){
        if(n<10)return n;
        return  n%10*(int)Math.pow(10,(int)Math.log10((double)n)) + reverse(n/10);
    } 

so this returns the last digit, multiplied by 10^current power + (recursive call)
