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 Java7 (OpenJDK 1.7.0) (judge verdict: Accepted)

import java.util.*;

public class Main {

  public static void main(String[] args) {
    Main m = new Main();
    m.exec();
  }

  private void exec() {
    Scanner scan = new Scanner(System.in);

    int n = scan.nextInt();
    int sum = 0;
    int tmp = n;
    do {
      sum += tmp % 10;
      tmp = tmp / 10;
    } while (tmp != 0);

    if (n % sum == 0) {
      System.out.println("Yes");
    } else {
      System.out.println("No");      
    }

    scan.close();
  }
