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

#include <stdio.h>

void main()
{
  int x = 0;
  int y = 0;
  
  scanf("%d%d", &x, &y);
  
  int grp2[5] = {4, 6, 9, 11};
  
  if(2 == x || 2 == y) {
	printf("No");
 	return;
  }
  
  int yes_flg = 0;
  for(int loop = 0; loop < 4; ++loop) {
    if(x == grp2[loop]) {
      yes_flg = 1;
      break;
    }
  }
 
  for(int loop = 0; loop < 4; ++loop) {
    if(y == grp2[loop]) {
        if(1 == yes_flg) {
			printf("Yes");
	        return;
        } else {
		  printf("No");
          return;
        }
    }
  }
  
  if(0 == yes_flg){
