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 Python (3.4.3) (judge verdict: Accepted)

import sys
import math

n = int(input())

# str_n = str(n)

# harshad = 0
# for i in range(len(str_n)):
#     harshad += int(str_n[i])

# print("Yes") if n%harshad == 0 else print("No")

harshad = 0
num = n
for i in range(len(str(n))):
    harshad += num % 10
    num = math.floor(num / 10)

print("Yes") if n%harshad == 0 else print("No")
