16

|
* |
|
17

18

* their actual event state) whether they should be deemed as matching a search |
|
19
|
|
|
* based on the dates of the search. For example, a hotel room can declare that it |

|
* should be unavailable if the check-in time is not at least 2 days away from the |
|
21
|
|

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
You can also find more detailed suggestions in the “Code” section of your repository.
