Commentary

• The explanation is the code I wrote, so if you have a better algorithm, please share it!

public class Solution {
    public int solution(int n) {
        //For saving totals
        int sum = 0;
        while(n > 0) {
            sum += n % 10; //Divide by 10 and add the remainder.
            n /= 10;  //Substitute in n to use the result of division by 10 for the next calculation.
        }

        return sum;
    }
}
