Problem Statement

An integer X is called a Harshad number if X is divisible by f(X), where f(X) is the sum of the digits in X when written in base 10.

Given an integer N, determine whether it is a Harshad number.

Constraints

1?N?10^8

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

Print Yes if N is a Harshad number; print No otherwise.

Sample Input 1

12

Sample Output 1

Yes

f(12)=1+2=3. Since 12 is divisible by 3, 12 is a Harshad number.

Sample Input 2

57

Sample Output 2

No

f(57)=5+7=12. Since 57 is not divisible by 12, 12 is not a Harshad number.

Sample Input 3

148

Sample Output 3

No

Solution in Scala (2.13.1) (judge verdict: Accepted)

object Main {
  def main(args: Array[String]): Unit = {
    val num = scala.io.StdIn.readInt
    if( isHarshadNumber( num ) ) println( "Yes" )
    else                         println( "No" )
  }

  def isHarshadNumber( input: Int ): Boolean = {
    var num = input
    var sum = 0
    while( num > 0 ) {
      sum += num%10
      num /= 10
    }

    if( input%sum == 0 ) return true
    else                 return false
  }
}
