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) {
		// TODO 自動生成されたメソッド・スタブ
		Scanner scan = new Scanner(System.in);
		int x = scan.nextInt();
		int y = scan.nextInt();
		int groX=0;
		int groY=0;

		if(x==4||x==6||x==9||x==11) {
			groX=2;
		}else if(x==2) {
			groX=3;
		}else {
			groX=1;
		}

		if(y==4||y==6||y==9||y==11) {
			groY=2;
		}else if(y==2) {
			groY=3;
		}else {
			groY=1;
		}

		if(groX==groY) {
			System.out.println("Yes");
		}else {
			System.out.println("No");
		}
	}
