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;
using System.Collections.Generic;
class Program
{
    static void Main(string[] args)
    {
        int[] A = { 1, 3, 5, 7, 8, 10, 12 };
        int[] B = { 4, 6, 9, 11 };
        int[] C = { 2 };
        int[] n = Console.ReadLine().Split(' ').Select(int.Parse).ToArray();
        if ((A.Contains(n[0]) && A.Contains(n[1])) ||
            (B.Contains(n[0]) && B.Contains(n[1])))
            Console.WriteLine("Yes");
        else
            Console.WriteLine("No");

    }
