Was already working on a fork. Unfortunately there's no way to fix the description without making this Kata an "educational" freebie kata, but i guess that's better than the 54% it has racked so far. Also upgraded to Chai

Description code examples have missing commas and misspelled function name.

i dont understand the description... what the heck are you asking for?

Your code is incorrect, you changed the function prototype in a way which made it wrong.

It's not a kata issue, you need to keep the original signature, or change it in a compatible way.

test does not compile in c++

I don't think you need two ifs for that. They are mutually exclusive

I had practically the same solution. Why did you include algorithm and iostream?
