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 in = new Scanner(System.in);
		
      long nam = in.nextLong();
      int cnt = String.valueOf( nam ).length();
      int sum = 0;
      
      long memo = nam;
      for(int i = 0;i < cnt;i++){
      		sum += memo%10;
        	memo /=10;
      }
      
      if(nam%sum==0){
         System.out.print("Yes"); 
      }else{
         System.out.print("No");
      }
