Interesting method/name: #clamp.

5 kyu, really? This is a trivial kata.

This is a very nice kata. Though my solution is shit :)

Under Ruby, my 10s of tests all pass. Then, when I submit, I get this:

page_index returned incorrect value when provided a item_index argument that was out of range

The tests provided in the discription pass too.

From the instructions:

Write a function that will convert a string into title case, given an optional list of exceptions (minor words).

It should be added that exceptions do not apply to the first word.
