I'm just now seeing this! I was very new to ruby and programming haha. I flinched and then smiled looking at this code just now ;)

Wow this is hard to read! Your brain is better than mine!

I don't see how this would be better than recursion and how you can put the characters in the middle of the string, if you ask me, but ok :)

Found a small problem in the template solution. Fixed!

Fixed!

My failing tests are expecting a joined string of the possibilities.

e.g. Testing for "?10011000"

Expected: "010011000110011000",

instead got: ["010011000", "110011000"]

For ruby..

How would this work if the number has a zero in it, e.g. "404" => 44

Ok, thanks

I'm not sure what your question is. It's specified clearly in the description it's the first character that you are looking for. Any unicode character counts. (Though, technically, I suppose the term codepoint would be more accurate, but I think enough people understand what a character is to get it.)

I keep get this error -> Expected: ",", instead got: ""
Why would the test expect a non-word character?
