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 Go (1.6) (judge verdict: Wrong Answer)

package main 

import (
        "fmt"
)


func main (){
        var a, b, d, e ,f   int
        fmt.Scan(&a)
        if  a % 7 == 0{
                fmt.Println("YES")
        } else if a % 4 == 0 {
                fmt.Println("YES")
        } else if a % 7 != 0 && a % 3 != 0 {
                 a = a / 7
                 b = a
                 for i := 0 ; i < a ; i++{
                         d += 1
                         e = 7 * b
                         f = 3 * d
                         if a % e / f ==0 {
                                 fmt.Println("Yes")
                         }
                         a -=1

                 }
         } else {
                 fmt.Println("No")
         }
 }
