Problem Statement

Based on some criterion, Snuke divided the integers from 1 through 12 into three groups as shown in the figure below.
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

            var x = inputs[0];
            var y = inputs[1];
            Console.WriteLine(x == 2 || y == 2 ? "No" : ((x == 4 || x == 6 || x == 9 || x == 11) ? ((y == 4 || y == 6 || y == 9 || y == 11) ? "Yes" : "No") : ((y == 4 || y == 6 || y == 9 || y == 11) ? "No" : "Yes")));
