#When a challenge asks for an array as input/output, you may use a list instead, and vice-versa

Note that some languages may lack one of these concepts. For example, TI-Basic does not have an array datatype (but has lists) and C does not have a list in its standard library, but has arrays as part of the language.

In keeping with the general flexibility of I/O formats, I suggest we allow to use them interchangeably for all languages.
