Scala translation

Approved

Nice!

Funny kata, congratulations.

the ambiguity imo comes from the fact that the input string is 'meaningless', so to speak, it's not already ordered in some format or case. therefore the case of the input is not important, and "JavaScript" would be translated into "Javascript" because it has no separators

So are you saying Mp3file/MP3file is correct and Mp3File/MP3File is incorrect? Then, at the very least, the expected behavior should be specified, I wouldn't expect it to be like this by default.

I dont think that's an issue, even though it might look a bit werid, it follows the rule of PascalCase / camelCase:
digits are valid components of a 'word', e.g. apply_rot13_func converted to PascalCase becomes ApplyRot13Func

JS:

camelize("SwIQKr2s23 zzyZy/dox") should equal "Swiqkr2s23ZzyzyDox"
expected 'Swiqkr2S23ZzyzyDox' to equal 'Swiqkr2s23ZzyzyDox'

That looks incorrect to me...

Approved :)

C translation (author gone)

it's still important to instill those concepts so that when you get to the more difficult, complicated real world problems, those concerns are on your mind.

nice kata
