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>

void main(int argc, char *argv[])
{
    int N, Sn, x, y;
    scanf("%d", &N);
    if (N < 1 || N > pow(10, 9))
        exit(1);
    y = N;
    while (y)
    {
        x = y % 10;
        Sn = Sn + x;
        y = y / 10;
    }
    if (Sn != 0 && N % Sn == 0)
        printf("Yes");
    else
        printf("No");
