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.*;
public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        String ns =String.valueOf(n);
        int len = ns.length();
        int num = 0;

        for(int i = 0;i<len;i++){
            num = num + (Character.getNumericValue(ns.charAt(i)));
            //System.out.println(Character.getNumericValue(ns.charAt(i)));
        }
        //System.out.println(num);
        if(n%num==0){
            System.out.println("Yes");
        }else{
            System.out.println("No");
        }
        
        
    }
}
