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()

    int a[7]={1,3,5,7,8,10,12};
    int b[4]={4,6,9,11};

    int p=5,q=6,r=5,s=6;
    scanf("%d %d",&x,&y);
    for (i=0;i<7;i++){

        if (x==a[i])
        {

        }
        if (y==a[i])

        }
    }
    if (p==q)
    {
