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 scala.io.StdIn

object Main extends App {
  val a = StdIn.readLine().split(" ").map(_.toInt)

  def gr2(n: Int) = n == 4 || n == 6 || n == 9 || n == 11
  
  val r = if(a(0) == 2 || a(1) == 2) "No"
  else if(gr2(a(0)) && gr2(a(1))) "Yes"
  else if(gr2(a(0)) || gr2(a(1))) "No"
  else "Yes"
  
  println(r)
  
}
