I know I'm 2 years late, but his code is about ~3 faster. Tested it with 1 and 10 million executions.

Oh, yes... I see...

but the return value will be retuned as an integer. it won't convert to a char. that's not what you want the function to do

Yeah

Since the return value of the function is char, you can simply replace char(i) with i.

You could have used init(repeating: String, count: Int) -> String in place of repeatElement

nice outside the box thinking

This is a less than ideal solution because it would count words that have "good" as a substring, but this isn't tested.

👍

clever!

Me too - just remove 'characters' from 'return str.characters.enumerated().map ' and it works ;)

This solution shows me the error "Value of type 'String' has no member 'capitalized'"

Thanks, the problem is on my side then

390 guys passed the C++ kata (see the top of the page), I just tried a few solutions and all worked fine. I don't see any mix in the vectors.

C++ :

The answer can't be right no matter what you do. The "cd" and "art" vectors are mixed up in the tests. So the "&lstOfArt" and "&categories" vectors get to the function in the wrong order.
