Given two integers x and y (1 ≤ x < y ≤ 12), determine whether they belong to the same group.

Constraints

x and y are integers.

1 ≤ x < y ≤ 12

Input

Input is given from Standard Input in the following format:

x y

Output

If x and y belong to the same group, print Yes; otherwise, print No.

Sample Input 1

1 3

Sample Output 1

Yes

Sample Input 2

2 4

Sample Output 2

No

Solution in PHP7 (7.0.15) (judge verdict: Wrong Answer)

<?php

$line = fgets(STDIN);
$arr = explode("　", $line);

$group = [];
foreach ($arr as $val) {
    switch ($val) {
      case 1:
      case 3:
      case 5:
      case 7:
      case 8:
      case 10:
      case 12:
        array_push($group, 1);
        break;
      case 4:
      case 6:
      case 9:
      case 11:
        array_push($group, 2);
        break;
      case 2:
        array_push($group, 3);
        break;    
    }
}

if($group[0] == $group[1]) {
    echo "Yes";
} else {
    echo "No";
}
