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 g = new[] { 0, 1, 3, 1, 2, 1, 2, 1, 1, 2, 1, 2, 1 };
    var a = Console.ReadLine().Split().Select(int.Parse).ToArray();
    Console.WriteLine(g[a[0]] == g[a[1]] ? "Yes" : "No");
  }
}
