Ozan Playlist Not Using Sets

[ievgenk]

Heya good people of Exercism,

Was just doing Ozan Playlist exercise and noticed that even though concept linked is "Sets" the exercise is using arrays instead. Is this intentional or has not been converted to sets yet?

Maybe I could help with that ?

Thanks for wonderful learning resource !

Or I guess, looking at other peoples' solutions they should be converted back to arrays?

No, I agree with your initial assessment. I have apparently "mastered" sets without actually using a set.

For me it boiled down to:

• use arrays, which I already understood and the exercise seemed to require; or
• use sets internally, then convert the sets back to arrays for the return. (But I didn't see anything in the lesson explaining how to convert from one to the other.) (Edit: The conversion instructions are there; I just didn't see 'em. Whoops.)

That said, I've been finding Exercism a very, very useful online resource.
