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 = Seq(1,3,5,7,8,10,12)
  val b = Seq(4,6,9,11)
  val c = Seq(2)

  val res = if(isSameGroup(x,y)) "Yes" else "No"

  println(res)

  def isSameGroup(x: Int, y: Int): Boolean ={
    ( a.contains(x) && a.contains(y) ) ||
    ( b.contains(x) && b.contains(y) ) ||
    ( c.contains(x) && c.contains(y) )
  }

}
