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 Scala (2.11.7) (judge verdict: Accepted)

import java.util.Scanner

object Main extends App {
  val sc = new Scanner(System.in)
  val x = sc.nextInt()
  val y = sc.nextInt()

  val a = Set(1, 3, 5, 7, 8, 10, 12)
  val b = Set(4, 6, 9, 11)

  println(if (x != 2 && y != 2 && (a.contains(x) && a.contains(y) || b.contains(x) && b.contains(y))) "Yes" else "No")
}
