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 Ruby (2.3.3) (judge verdict: Accepted)

a=gets.split("").map(&:to_i)
a=a[0..-2]

b=0

i=-1
loop{
  unless a[i]  
    break
else
    k=10**(-i-1)
    b+=a[i]*k
end
i-=1
    
}

sum=a.inject(:+)


if b%sum==0
    puts "Yes"
else
    puts "No"
end
