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>
#include<string.h>

int judge_group(int a){
    int group;

    switch (a){
    case 1:
    case 3:
    case 5:
    case 7:
    case 8:
    case 10:
    case 12:
        group = 1;
        break;

    case 4:
    case 6:
    case 9:
    case 11:
        group = 2;
        break;

    case 2:
        group = 3;
        break;
    }

    return group;
}

int main(void){

    int x,y,x_group,y_group;

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

    x_group = judge_group(x);
    y_group = judge_group(y);

    (x_group == y_group) ? printf("Yes\n") : printf("No\n");
    return 0;
}
