Unpublishing as a task similar to existing kata.
Please consider adding a translation to Strings: starts with (check for prefix), Did you mean ...? (filtering of a list of words), or other, similar kata.
I just translated Strings: starts with. Check it out.
Trivial map/filter/reduce is not a novel kata idea.
It's almost a duplicate of Strings: starts with.
The description should state clearly what to do in case there's no match (and this case should always appear in a battery of tests).
Done
It looks like a duplicate of similar katas that ask to find a matching word from a dictionary.
Also, I doubt that returning different data types is appropriate: IDK whether it's acceptable in Lua, but this requirement would make it harder to translate to other languages.
It would be more coherent to return both the number of matches and the words matching in all cases.
I changed the return data type to a single one.
