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) = scala.io.StdIn.readLine.split(" ").map(_.toInt)

	val a1 = Set(1,3,5,7,8,10,12)
	val a2 = Set(4,6,9,11)
	val a3 = Set(2)

	if(a1.contains(x) && a1.contains(y)){
		println("Yes")
	}else if(a2.contains(x) && a2.contains(y)){
		println("Yes")
	}else if(a3.contains(x) && a3.contains(y)){
		println("Yes")
	}else{
		println("No")
	}
