 Sum of digits (Recursion)

Problem Statement

Given a number N, find the sum of all the digits of the number

Note: Use a recursive method to solve this problem.

static long  Sum(long  n) 

    {   long sum = 0;

 

        while (n != 0) {

            sum = sum + n % 10;

            n = n / 10;

        }

 

        return sum;

        }
