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(void){
    int A,B;
    scanf("%d %d",&A,&B);
    if((A==2)&&(B==2)){
        printf("Yes");
    }else if(((A==4)||(A==6)||(A==9)||(A==11))&&((B==4)||(B==6)||(B==9)||(B==11))){
        printf("Yes");
    }else if(((A==1)||(A==3)||(A==5)||(A==7)||(A==8)||(A==10)||(A==12))&&((B==1)||(B==3)||(B==5)||(B==7)||(B==8)||(B==10)||(B==12))){
        printf("Yes\n");
    }else{
        printf("No\n");
    }
    return 0;
}
