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==1 || x==3 || x==5 || x==7 || x==8 || x==10 || x==12){
                if(y==4 || y==6 || y==9 || y==11)
                        printf("No\n");
                else
                       printf("Yes\n");
        }
        else{
                if(y==4 || y==6 || y==9 || y==11)
                        printf("Yes\n");
                else
                        printf("No\n");
        }

        return 0;
