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 Program
{
	static void Main()
	{
		var groupA = new[] { 1, 3, 5, 7, 8, 10, 12 };

		var n = Array.ConvertAll(Console.ReadLine().Split(new[] { ' ' }), number => int.Parse(number));

		var groups = Array.ConvertAll(n, num => {
			if (num == 2) {
				return 3;
			} else if (groupA.Contains(num)) {
				return 2;
			} else {
				return 1;
			}
		});

		Console.WriteLine(groups[0] == groups[1] ? "Yes" : "No");
	}
