I think this solution is faulty? Because according to title case some words should be kept lower case like "of" for example. But according to camelCase all subsequent words of the first one should be kept uppercase. Now this is a problem with the Kata as well since it actually test PascalCase, not camelCase. But the problem still stands as PascalCase should uppercase each new word.

The kata is called CamelCase but expects to produce PascalCase text
