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: Wrong Answer)

#include<stdio.h>
int main(void){
  int x,y,a,b,c;
  scanf("%d %d",&x,&y);
  if(x < y){
    if(x == 2){
      printf("no\n");
    }else{
      if(x == 4 || x == 6 || x == 9 || x == 11){
	if(y == 4 || y == 6 || y == 9 || y == 11){
	  printf("yes\n");
	}else{
	  printf("no\n");
	}
      }
      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");
	}else{
	  printf("no\n");
	}
      }
    }
  }
  return 0;	     
}
