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;
    scanf("%d%d",&x,&y);
    if(x==2||y==2) printf("No\n");
    else if((x<8&&x%2==1)&&((y<8&&y%2==1)||(y>7&&y%2==0))) printf("Yes\n");
    else if(x>7&&x%2==0&&y%2==0) printf("Yes\n");
    else if((x<7&&x%2==0)&&((y<7&&y%2==0)||(y>8&&y%2==1))) printf("Yes\n");
    else if(x==9&&y==11) printf("Yes\n");
    else printf("No\n");
    return 0;
}
