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>

int main(){
   int x,y;
   scanf("%d%d",&x,&y);
   if(x==2 || y==2){
    printf("No\n");
    return 0;
   }
  else 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){
        printf("Yes\n");
        return 0;
    }
    else{
        printf("No\n");
        return 0;
    }
   }
   else if(x==4 ||x==6 ||x==9 || x==11){
    if(y==4 ||y==6 ||y==9 || y==11){
        printf("Yes\n");
        return 0;
    }
    else{
        printf("No\n");
        return 0;
    }
   }
   else return 0;
