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[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)
            {
                count++;
                if(a[i]==y);
                count++;
            }
