Problem Statement

Let S(n) denote the sum of the digits in the decimal notation of n.
For example, S(101) = 1 + 0 + 1 = 2.

Given an integer N, determine if S(N) divides N.

Constraints

1 \leq N \leq 10^9

Input

Input is given from Standard Input in the following format:

N

Output

If S(N) divides N, print Yes; if it does not, print No.

Sample Input 1

12

Sample Output 1

Yes

In this input, N=12.
As S(12) = 1 + 2 = 3, S(N) divides N.

Sample Input 2

101

Sample Output 2

No

As S(101) = 1 + 0 + 1 = 2, S(N) does not divide N.

Sample Input 3

999999999

Sample Output 3

Yes

#include<stdio.h>
#include<string.h>
#include<math.h>
int main (){
	long long int a=0,b,i,c=0,f;
	scanf("%lld",&a);
	b=a;
	while(a!=0){
    c=c+a%10;
    a=a/10;	
	}
	
	if(b%c==0){
		printf("Yes\n");
		}
	else printf("No\n");
	return 0;
