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 <bits/stdc++.h>
using namespace std;
 
int main(){
  int x,y,z;
  cin>> x>>y;
  if((x==1)||(x==3)||(x==5)||(x==7)||(x==8)||(x==10)||(x==12)){
    x=1;
  }
  if((x==4)||(x==6)||(x==9)||(x==11)){
    x=4;
  }
  if((y==1)||(y==3)||(y==5)||(y==7)||(y==8)||(y==10)||(y==12)){
    y=1;
  }
  if((y==4)||(y==6)||(y==9)||(y==11)){
    y=4;
  }
  if(x==y){
    cout<<"Yes"<<endl;
    return 0;
  }
  cout<<"No"<<endl;
  
}
