Write a recursive function that returns the sum of the digits of a given integer.
Input format :
Integer N
Output format :
Sum of digits of N
Constraints :
0 <= N <= 10^9
Sample Input 1 :
12345
Sample Output 1 :
15
Sample Input 2 :
9
Sample Output 2 :
9

Solution://///////////

public class solution {

    public static int sumOfDigits(int input){
        int sum;
        if(input<10){
            return input;
        }
        sum = (input % 10) + sumOfDigits(input / 10);
        return sum; 

    }
}..
