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 ary = scala.io.StdIn.readLine().split(" ")
    val l1 = List(1,3,5,7,8,10,12)
    val l2 = List(4,6,9,11)
    val l3 = List(2)
    val a = ary(0).toInt
    val b = ary(1).toInt
    
    if (isExist(l1,a,b) || isExist(l2,a,b) || isExist(l3,a,b)) {
        println("Yes")
    } else {
        println("No")
    }

    def isExist(list: List[Int], a: Int, b: Int): Boolean =
        list.exists(_==a) && list.exists(_==b)
}
