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 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main(void)
{
    int n, i, j,total = 0;
    scanf("%d", &n);

    for (i = 0; (4 * i) < n; i++)
    {
        for (j = 0; ((7 * j) < n); j++)
        {
            total = (4 * i) + (7 * j);
            if (total == n) goto yes;
            else if (4 * i == n || 7 * j == n) goto kaihi;
        }
    }

    printf ("No");
    return (0);

    yes:
        printf("Yes");
        return (0);

    kaihi:
        printf("Yes");
        return (0);

}
