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 Kotlin (1.0.0) (judge verdict: Accepted)

import java.util.*

val sc = Scanner(System.`in`)
val N = sc.nextInt()

fun main(args: Array<String>) {
    print(if (N % f(N) == 0) "Yes" else "No")
}

fun f(X: Int): Int {
    var x = X
    var result = 0
    repeat(x.toString().length) {
        result += x % 10
        x /= 10
    }
    return result
}
