Using CultureInfo.CurrentCulture.TextInfo.ToTitleCase is a good attempt to simplify capitalization, but it won’t fully work for Jaden Case in this context. ToTitleCase capitalizes the first letter of each word but does not affect subsequent letters. For example, ToTitleCase("hELLO wORLD") would result in "HELLO WORLD", which isn’t what Jaden Case requires. Jaden Case should only capitalize the first letter of each word and keep the rest in lowercase.

To fix this, you can convert the phrase to lowercase first, ensuring only the first letter of each word is capitalized:

CultureInfo.CurrentCulture.TextInfo.ToTitleCase(phrase.ToLower());

A faster approach would be to just use two for loops and have loop 'j' run when j < i. Then, you'd keep the logic of your if statement for the hyphen.

I love this solution

Would this not work with words like "of" or "the"?

The most concise version!

Pretty, kind of clever, but not the cleverest nor very performant. Why iterate twice when you can have a single for loop?

Instead of one run in search of the maximum and minimum , it is run twice here.

The solution is not suitable for cases where the user suddenly wants to write a word through Caps Lock

I think that's what they meant, it would be more performant to use a StringBuilder in this case.

Hm, very very clever.
