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 Go (1.14.1) (judge verdict: Accepted)

package main

import "fmt"

func main() {
	// Code for B - Digit Sums
	var N int
	fmt.Scanf("%d", &N)

	var NN int = N
	var S int
	for {
		S += NN % 10
		A := NN / 10
		if A == 0 {
			break
		} else {
			NN = A
		}
	}
	if N%S == 0 {
		fmt.Println("Yes")
	} else {
		fmt.Println("No")
	}
}
