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 scan = new Scanner(System.in);
            
        String a = scan.next();
        String cnt;
        
        int sum = 0;
        
        for( int i = 0 ; i < a.length() ; i++ ){
          int s2integ = Integer.parseInt(a.substring(i,i+1));
          sum += s2integ;
        }
        
        int s_num = Integer.parseInt( a );
        
        if( s_num % sum == 0 )cnt = "Yes";
        else cnt = "No";
            
        System.out.println(cnt);
	  }
