Problem Statement

La Confiserie d'ABC sells cakes at 4 dollars each and doughnuts at 7 dollars each.
Determine if there is a way to buy some of them for exactly N dollars. You can buy two or more doughnuts and two or more cakes, and you can also choose to buy zero doughnuts or zero cakes.

Constraints

N is an integer between 1 and 100, inclusive.

Input

Input is given from Standard Input in the following format:

N

Output

If there is a way to buy some cakes and some doughnuts for exactly N dollars, print Yes; otherwise, print No.

Sample Input 1

11

Sample Output 1

Yes

If you buy one cake and one doughnut, the total will be 4 + 7 = 11 dollars.

Sample Input 2

40

Sample Output 2

Yes

If you buy ten cakes, the total will be 4 \times 10 = 40 dollars.

Sample Input 3

3

Sample Output 3

No

The prices of cakes (4 dollars) and doughnuts (7 dollars) are both higher than 3 dollars, so there is no such way.

Solution in C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<bits/stdc++.h>
using namespace std;
int N;

int ans() {
  int count = 0;
  for (int i = 0; i <= N / 4; i++) {
    for (int j = 0; j <= N / 7; j++) {
      int sum = i * 4 + j * 7;
      if (sum == N) {
        count++;
      }
    }
  }
  return count;
}


int main(void) {
  cin >> N;
  int res = ans();
  if(res > 0 ){
    cout << "Yes" <<endl;
  } else {
    cout << "No" <<endl;
  }
  return 0;
}
