You can even leave the "self." out. :-)

I can think of several approaches to solve this:

1. order the array and do a second iteration where each item is
checked against the last seen prefix; the idea is that every string
comes before the strings that contain it as prefix.

2. insert names into a tree and output only prefixes during a tree walk.

B�vue, the only issue I see with your method naming is that in Ruby
methods typically use under_scores and not CamelCase as in Java.

Kind regards
