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"
)

var group = []int{1, 3, 1, 2, 1, 2, 1, 1, 2, 1, 2, 1}

func main() {
  var x, y int; fmt.Scan(&x, &y)
  ans := "No"; if group[x-1] == group[y-1] {ans = "Yes"}
  fmt.Println(ans)  
}
