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(void)
{
    int x,y,a=0,b=0;
    scanf("%d%d",&x,&y);
    if(x==4||x==6||x==9||x==11)a++;
    else if(x==2)a+=2;
    if(y==4||y==6||y==9||y==11)b++;
    else if(y==2)b+=2;
    puts(a-b?"No":"Yes");
    return 0;
}
