I think it would be considered very bad code habit to hardcode values that are dependent of the database used. This is true generally and in this case specifically since it�s highly likely that the database file could be expanded with more destinations/origins; possibly even by the examiner when
testing!
So in my opinion: don�t hardcode these values. It could probably result in a penalty since it's bad coding style and the assignment hints that we should have the expansion possibilities in mind.
