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,M,x=0,y=1,i,j;
  cin >>N ;
  M=N;
 
 for(i=7;i>=0;i--){
    for(j=i;j>0;j--){
      y*=10;
    }
    x+=M/y;
    M=M%y;
    y=1;
  }

  
  if(N%x==0){
    cout <<"Yes";
  }
  else{
    cout <<"No";
  }
