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

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var g = new int[] { 0, 1, 3, 1, 2, 1, 2, 1, 1, 2, 1, 2, 1 };

            var ss = Console.ReadLine().Split();
            var x = int.Parse(ss[0]);
            var y = int.Parse(ss[1]);

            Console.WriteLine(g[x] == g[y] ? "Yes" : "No");
        }
    }
}
