2Yes any language is fine. Sorry I am new to this. Thank you! – Arlene – 2018-05-29T22:06:43.093
@Arlene Thank you and welcome to PPCG! – JayCe – 2018-05-30T00:01:14.243
@Arlene Please edit your question to reflect the fact that all languages are allowed. Also if you are interested in the shortest solution, I suggest you tag your question [tag:code-golf] – JayCe – 2018-05-30T00:04:22.833

Welcome to PPCG! That's a nice challenge, but unfortunately, we don't like challenges that allow only one language. This challenge is also missing a winning criteria. I'd recommend you to look at few other of challenges there and use our sandbox next time.
– RedClover – 2018-05-28T17:56:06.663I'm guessing this must be code golf as I can't see any other reasonable criteria. (I added the code golf tag, but if that is wrong feel free to specify the correct winning criteria and remove it.) – Jonathan Allan – 2018-05-28T18:09:43.360
6@Arlene what should we return for

@JonathanAllan Please stop editing programming questions to make them on-topic. Either OP edit the winning criteria in themselves or we close (and optionally someone else repost) it.

I think the challenge is too easy – mbomb007 – 2018-05-30T14:33:17.337
