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# (.NET Core 3.1.201) (judge verdict: Accepted)

using System;
namespace b
{
  class program
  {
    static void Main()
    {
      var n= Console.ReadLine();
      int ln=n.Length;
      var n1= Convert.ToInt32(n);
      int n2=0;
      for (int i =0;i<ln;i++)
      {
        var an = Convert.ToString(n[i]);
        var a = int.Parse(an);
        n2+=a;
      }
      if (n1%n2==0)
      {
        Console.WriteLine("Yes");
      }
      else
      {
        Console.WriteLine("No");
      }
    }
  }
