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 (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <stdio.h>

int main(void){
    int x,y;
    
    scanf("%d %d",&x,&y);
    
    if(y<=7 || x>=8){
        if((y-x)%2==0 && x!=2)
            printf("Yes\n");
        else
            printf("No\n");
    }
    else
        if((y-x)%3==0)
            printf("Yes\n");
        else
            printf("No\n");
}
