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, y = sc.nextInt()

  val S = Set(4, 6, 9, 11)

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