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 {
  def main(args:Array[String]): Unit = {
    val groups:List[List[Integer]] = List(List(1, 3, 5, 7, 8, 10, 12), List(4, 6, 9, 11), List(2))
    val sc = {
      new Scanner(System.in)
    }
    val x, y = sc.nextInt

    var answer = "No"

    groups.foreach( group => {
      if (group.contains(x) && group.contains(y)) {
        answer = "Yes"
      }
    })

    println(answer)
  }
}
