// CPP implementation of above approach

  

#include <bits/stdc++.h>

using namespace std;

  

// Function to check

// if the given number is divisible

// by sum of its digits

string isDivisible(long long int n)

{

    long long int temp = n;

  

    // Find sum of digits

    int sum = 0;

    while (n) {

        int k = n % 10;

        sum += k;

        n /= 10;

    }

  

    // check if sum of digits divides n

    if (temp % sum == 0)

        return "YES";

  

    return "NO";

}

  

// Driver Code

int main()

{

    long long int n = 123;

  

    cout << isDivisible(n);

  

    return 0;

}
