Same! Add in some Infinity, NaN, 'More please' etc. into the tests as well to get some basic validation and a bit of fun

PascalCase not camelCase
When will people learn?

I'm amazed to see so few approaches like this... memoization was my first thought!

Case

This would be nice if the kata description were more complete
Looking over the solutions, almost none are approaching production quality. You don't need regexes or some byzantine logic. The time available is easily adequate as your select should complete in << 1 second.
Real incoming data has Mr, Dr etc. in (as this has), with all sorts of separators from commas to slashes. Some at work includes 'MRS DR PROF' and such, sometimes as a prefix, sometimes as a suffix.

I like ur solution, need to keep in mind it

+1 to "too simple" (python)

There is a concept of lower camel case, and of upper camel case. Upper camel case is also known as Pascal case, but not exclusively known as Pascal case. Your own article that you linked indicates this in the top section of the document. This kata doesn't not specificy upper or lower, it just says "camel case", but specifically states that it should be upper if the original source was capitalized, and lower in all other cases.

Some programming styles prefer camel case with the first letter capitalised, others not

From your own wikipedia link. Your absolutist opinion that "camel case" is and only is the lower camel variant is just wrong.

Some people and organizations, notably Microsoft, use the term camel case only for lower camel case. Pascal case means only upper camel case.

Also from your article. You clearly are one of these people, but as you can see here, its not a universal opinion.

The tricky, and beautiful, task here is to figure out that this is the case.

Nicely written kata. It feels like it could be built upon to make a higher tier kata with multiple rolls / battles quite easily.

If you can find some examples that would result in floating point errors, that would be a good test, many of the current solutions would fail such a test.
