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

#include<stdio.h>
int main(void)
{
    int a[10]={1,3,5,7,8,10,12};
    int b[10]={4,6,9,11};
    int c[10]={2},x,y,i,count=0,count2=0;
    scanf("%d %d",&x,&y);
    if(x,y>=1&&x,y<=12){
        for(i=0;i<7;i++){
            if(a[i]==x|a[i]==y){
                count++;
            }
        }
        for(i=0;i<4;i++){
            if(b[i]==x|b[i]==y){
                count2++;
            }
        }
        if(count==2|count2==2){
            printf("Yes");
        }
        else{
            printf("No");
        }
    }
    return 0;
