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

		String in = scanner.nextLine();
		int a = Integer.parseInt(in);
		
		int base = a;
		int sum = 0;
		int dig = 0;
		while (a > 0) {
			dig = a % 10;
			sum += dig;
			a = a / 10;
		}
		
		if (base % sum == 0) {
			System.out.println("Yes");
		} else {
			System.out.println("No");
