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>
int main() {
long long a, i, x = 0;
scanf("%lld", &a);
for (;;) {
i = a % 10;
x = i + x;
if (a / 10 < 10) {
break;
} 
a = a / 10;
} if (a % x == 0) {
printf("Yes\n");
} else {
printf("No\n");
}
return 0;
}
