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,c1,c2;
  scanf("%d%d",&x,&y);
  if((x==4||x==6)||(x==9||x==12))
    c1=2;
  else if(x==2)
    c1=3;
  else
    c1=1;
  if((y==4||y==6)||(y==9||y==12))
    c2=2;
  else if(x==2)
    c2=3;
  else
    c2=1;
  if(c1==c2)
    printf("Yes\n");
  else
    printf("No\n");
  return 0;
}
