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 sc = new Scanner(System.in);
		int x = sc.nextInt();
		int y = sc.nextInt();
		int a = 0;
		int b = 0;

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

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


		if ( a == b) {
			System.out.println("Yes");
		} else {
			System.out.println("No");
		}
	}
