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 main() {
	var x, y int
	fmt.Scan(&x, &y)
	if x == 4 || x == 6 || x == 9 || x == 11 {
		if y == 4 || y == 6 || y == 9 || y == 11 {
			fmt.Println("Yes")
			return
		}
	}
	if x == 1 || x == 3 || x == 5 || x == 7 || x == 8 || x == 10 || x == 12 {
		if y == 1 || y == 3 || y == 5 || y == 7 || y == 8 || y == 10 || y == 12 {
			fmt.Println("Yes")
			return
		}
	}
	fmt.Println("No")
}
