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;

int main() {
  int x, y;
  cin >> x >> y;
  bool b1, b2 = false;
  if(x == 4 || x == 6 || x == 9) {
    if(y = 6 || y == 9 || y == 11) {
      cout << "Yes";
    }
  }
  else if(x == 1 || x == 3 || x == 5 || x == 7 || x == 8 || x == 10) {
    if(y == 12 || y == 3 || y == 5  || y == 7 || y == 8 || y == 10) {
      cout << "Yes";
    }
  }
  else {
    cout << "No";
  }
}
