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 Go (1.6) (judge verdict: Accepted)

package main

import "fmt"

func getGroup(a int) (b int){
  switch a{
  case 1,3,5,7,8,10,12: b = 0
  case 4,6,9,11: b = 1
  case 2: b = 2
  }
  return
}

func main(){
  var x, y int
  fmt.Scan(&x, &y)
  if getGroup(x) == getGroup(y){
    fmt.Println("Yes")
  }else{
    fmt.Println("No")
  }
}
