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 9.2.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main(void)
{
    int x,y;
    int a=0,b=0;
  
    scanf("%d%d",&x,&y);
    if((x==1)||(x==3)||(x==5)||(x==7)||(x==8)||(x==10)||(x==12))
      a++;
    if((y==1)||(y==3)||(y==5)||(y==7)||(y==8)||(y==10)||(y==12))
      b++;
    if((a==1)&&(b==1)) { printf("Yes\n"); return 0; }
    
    if((x==4)||(x==6)||(x==9)||(x==11))
      a++;
    if((y==4)||(y==6)||(y==9)||(y==11))
      b++;
    if((a==1)&&(b==1)) { printf("Yes\n"); return 0; }
    
    if((x==2)&&(y==2)) { printf("Yes\n"); return 0; }
  
    printf("No\n");
    
    return 0;
}
