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

using System.Collections.Generic;

namespace Atcoder
{
    class Program
    {
        static void Main(string[] args)
        {
            var x = InputNumList();
            var a = new List<int> { 0, 2, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0 };

            WriteLine(a[x[0] - 1] == a[x[1] - 1] ? "Yes" : "No");
        }

        static int InputNum()
        {
            return int.Parse(ReadLine());
        }
        static List<int> InputNumList()
        {
            return ReadLine().Split(' ').Select(int.Parse).ToList();
        }
