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<iostream>
#include<cstring>
using namespace std;
int main(){
	string a;
	int x=0,y=0,i;
	cin>>a;
	for(i=0;i<a.length() ;i++){
		x+=a[i]-48;
		y+=a[i]-48;
		if(i!=a.length()-1){
			y*=10;
		}
	}
	if(y%x==0){
		cout<<"Yes";
	}
	else cout<<"No";
	return 0;
