TestDome's AI reviews your code formatting. Use:

public static DatabaseConnection getInstance() if (instance == null) synchronized (DatabaseConnection.class) if (instance == null) instance = new DatabaseConnection(); However, note that ways(1) = 1 and ways(2) = 2

Thus, ways(n) = ways(n-1) + ways(n-2) , which is identical to the Fibonacci series. However, note that ways(1) = 1 and ways(2) = 2 . This means ways(n) = Fibonacci(n+1) .
