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 f(x int) int {
	switch x {
	case 1, 3, 5, 7, 8, 10, 12:
		return 31
	case 2:
		return 28
	default:
		return 30
	}
}

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