Problem Statement

Let S(n) denote the sum of the digits in the decimal notation of n.
For example, S(101) = 1 + 0 + 1 = 2.

Given an integer N, determine if S(N) divides N.

Constraints

1 \leq N \leq 10^9

Input

Input is given from Standard Input in the following format:

N

Output

If S(N) divides N, print Yes; if it does not, print No.

Sample Input 1

12

Sample Output 1

Yes

In this input, N=12.
As S(12) = 1 + 2 = 3, S(N) divides N.

Sample Input 2

101

Sample Output 2

No

As S(101) = 1 + 0 + 1 = 2, S(N) does not divide N.

Sample Input 3

999999999

Sample Output 3

Yes

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        int result = 0;
        if(1<=Integer.parseInt(a)&&Integer.parseInt(a)<=(Math.pow(10,9))){
            for (int i = 1; i<(a.length()+1); i++){
                int kekka = Integer.parseInt(a.substring(i-1, i));
                int hai = 0;
                result += kekka;
            }
            if((Integer.parseInt(a)%result) == 0){
                System.out.println("YES");
            }else{
                System.out.println("NO");
            }
        }
    }
