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)

public class Hello{
    public static void Main(){

        string[] num = System.Console.ReadLine().Split(' ');
        int[] group ={1,3,1,2,1,2,1,1,2,1,2,1};
        int x = int.Parse(num[0]);
        int y = int.Parse(num[1]);

        if(group[x - 1] == group[y - 1]){
            System.Console.WriteLine("Yes");
        }else{
            System.Console.WriteLine("No");
        }
    }
}
