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++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <bits/stdc++.h>
using namespace std;
#define rep(i, n) for (int i = 0; i < (int)(n); i++)
 
int main(){
  int a, b;
  int x, y;
  cin >> a >> b;
  if(a==2)x=1;
  else if(a==4||a==6||a==9||a==11){x=2;}
  else{x=3;}
  
  if(b==2)y=1;
  else if(b==4||b==6||b==9||b==11){y=2;}
  else{y=3;}
  
  if(x=y)cout << "Yes" << endl;
  else{cout<<"No" << endl;}

  return 0;
