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

int main(void)
{
    int a, b;

    scanf("%d  %d", &a, &b);
    if (check(a) == check(b))
        printf("YES");
    else
        printf("NO");

    return 0;
}
