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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int group(int x){
  if(x==2)
    return 1;
  else if(x==4||x==6||x==9||x==11)
    return 2;
  else
    return 3;
}

int main(void){
  int x,x1,y,y1;

  scanf("%d %d",&x,&y);

  x1=group(x);
  y1=group(y);

  if(x1==y1)
    printf("Yes\n");
  else
    printf("No\n");

  return 0;
}
