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

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Linq;
class A{
  static void Main(){
    var arr = new int[] { 4, 6, 9, 11 };
    var s = Array.ConvertAll(Console.ReadLine().Split(' '), int.Parse);
    Console.WriteLine(!s.Contains(2) && arr.Contains(s[0]) == arr.Contains(s[1])?"Yes":"No");
  }
}
