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

using System;

using System.Collections.Generic;

public class Hello
{
    static void Main()
    {
        int num = int.Parse(Console.ReadLine());
        int fx = num;
        int amari = 0;


        while (num > 0)
        {
            amari += num % 10;
            num /= 10;
        }

        if (fx % amari == 0) Console.WriteLine("Yes");
        else Console.WriteLine("No");
    }
}
