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 PHP (5.6.30) (judge verdict: Accepted)

<?php
$N = trim(fgets(STDIN));

if ($N % 4 == 0 || $N % 7 == 0)
{
    echo 'Yes';
}
else
{
    $i = 1;
    do 
    {
        $tmp = $N - 7 * $i;
        if ( $tmp < 0)
        {
            echo 'No';
            break;
        }
        if ( $tmp % 4 == 0 )
        {
            echo 'Yes';
            break;
        }
        else
        {
            $i++;
        }
    } while($i <= 14);
}
?>
