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 C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>
#include<stdlib.h>
#include<math.h>
int main(){
   int x , y  ;
   scanf("%d%d",&x , &y);

   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)){
    printf("Yes");
   }else if((x==4 || x==6 || x==9 || x==11)&& (y==4 || y==6 || y==9 || y==11)){
    printf("Yes");
   }else if(x==2 && y ==2){
    printf("Yes");
   }else{
    printf("No");
   }
