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 ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(Console.ReadLine().Split(' ').Select(w => int.Parse(w)).Aggregate((n, m) => (n == 2 || m == 2 ? 0 : ((n == 4 || n == 6 || n == 9 || n == 11) ? ((m == 4 || m == 6 || m == 9 || m == 11) ? 1 : 0) : ((m == 4 || m == 6 || m == 9 || m == 11) ? 0 : 1)))) == 0 ? "No" : "Yes");
        }
    }
