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

#include <bits/stdc++.h>
using namespace std;

int main()
{
	int n;
	cin>>n;
	int t=n;
	int ans=0;
	while(t)
	{

		ans+=t%10;
		t/=10;
	}
	if(n%ans==0)
	{
		puts("Yes");
	}
	else
	{
		puts("No");
	}


	return 0;
