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: Accepted)

#include <bits/stdc++.h>
using namespace std;

int group(int n)
{
  if (n == 2) return 0;
  if (n == 4 || n == 6 || n == 9 || n == 11) return 1;
  return 2;
}

int main()
{
  int x, y;
  cin >> x >> y;
  
  string ans = "No";
  if (group(x) == group(y)) ans = "Yes";
  
  cout << ans << endl;
}
