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)

object Main extends App {
  val Array(x, y) = io.StdIn.readLine.split(" ").map(_.toInt)
  def f(n:Int):Int = {
    if(n == 2) 3
    else if(n == 4 || n == 6 || n == 9 || n == 11) 2
    else 1
  }
  val ans = if(f(x) == f(y)) "Yes" else "No"
  println(ans)
}
