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 {
	public static void main(String[] args){
		Scanner in = new java.util.Scanner(System.in);
		int x = in.nextInt();
		int y = in.nextInt();
		int xg=1, yg=1;
		int[] g2 = {4,6,9,11};
		if(x == y){
			System.out.println("Yes");
			System.exit(0);
		}
		if(x == 2 || y == 2){
			System.out.println("No");
			System.exit(0);
		}
		for(int i=0; i<g2.length; i++){
			if(x == g2[i]){
				xg = 2;
			}
			if(y == g2[i]){
				yg = 2;
			}
		}

		if(xg == yg){
			System.out.println("Yes");
		}else{
			System.out.println("No");
		}
		
	}
