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

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

namespace Beginner101
{
    class Program
    {
        static void Main(string[] args)
        {
            var hoge = Console.ReadLine();
            var ans ="";
            
            var sum = 0;
            for(int i=0; i < hoge.Length; i++) {
                sum += int.Parse(hoge[i].ToString());
            }
            ans = (int.Parse(hoge) % sum== 0)?"Yes":"No";
            Console.WriteLine(ans);
        }
    }
}
