Problem Statement

An integer X is called a Harshad number if X is divisible by f(X), where f(X) is the sum of the digits in X when written in base 10.

Given an integer N, determine whether it is a Harshad number.

Constraints

1?N?10^8

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

Print Yes if N is a Harshad number; print No otherwise.

Sample Input 1

12

Sample Output 1

Yes

f(12)=1+2=3. Since 12 is divisible by 3, 12 is a Harshad number.

Sample Input 2

57

Sample Output 2

No

f(57)=5+7=12. Since 57 is not divisible by 12, 12 is not a Harshad number.

Sample Input 3

148

Sample Output 3

No

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.*;
 
public class Main{
  public static void main(String[] args){
    
    Scanner sc = new Scanner(System.in);
    
    String N = sc.next();
    int sum = 0;
 
    for(int i = 0; i < N.length(); i++){
      int a =Integer.parseInt(N.substring(i, i+1)); 
      sum += a;
    }
    
    int total = Integer.parseInt(N);
    String output = null;
    
    output = (total % sum == 0) ? "Yes":"No";
    System.out.println(output);
  }
}
