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 handan(int i);
 
int main(void)
{
   int x,y;
 
   scanf("%d%d",&x,&y);
 
   x=handan(x);
   y=handan(y);
 
   if(x==y)
      printf("Yes\n");
   else
      printf("No\n");
   return 0;
}
 
int handan(int i)
{
   int a;
 
   if(i==2) a=2;
   else if((i==4)||(i==6)||(i==9)||(i==11)) a=1;
   else a=0;
   return a;
}
