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 a,b;
scanf ("%d%d",&a,&b);
  if (a==2 || b==2){
  printf ("No");
  }
  else {
  if (a==4 || a==6 || a==9 || a==11){
  if (b==4 || b==6 || b==9 || b==11){
  printf ("Yes");
  }
  else {printf ("No");}
  }
  else{
  if(b==4 || b==6 || b==9 || b==11){
  printf ("No");
  }
    else{
    printf ("Yes");
    }
  }
  }
return 0;
}
