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 Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.Scanner;

public class Main {

    private static boolean grouped(int[] grp, int x, int y) {
        boolean bx = false;
        boolean by = false;

        for (int i = 0; i < grp.length; i++) {
            if (grp[i] == x) {
                bx = true;
            }
            if (grp[i] == y) {
                by = true;
            }
        }

        return bx && by;
    }

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int x = sc.nextInt();
        int y = sc.nextInt();

        int[] grp1 = {1, 3, 5, 7, 8, 10, 12};
        int[] grp2 = {4, 6, 9, 11};
        int[] grp3 = {2};

        System.out.println( (grouped(grp1, x, y) || grouped(grp2, x, y)) ? "Yes" : "No" );
    }
