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"
//	"strconv"
//	"sort"
//	"math"
//	"regexp"
)


var x,y int

func main(){
	fmt.Scan(&x,&y)

	if x == 2 && y==2 {
		fmt.Println("Yes")
	}else if (x == 4 ||x == 6||x == 9||x == 11) && (y == 4||y == 6||y == 9||y==11){
		fmt.Println("Yes")
	}else if (x == 1 ||x == 3||x == 5||x == 7||x == 8||x == 10||x == 12) && (y == 1 ||y == 3||y == 5||y == 7||y == 8||y == 10||y == 12){
		fmt.Println("Yes")
	}else{
		fmt.Println("No")
	}
}
