This is an implementation of the kata08 (http://codekata.com/kata/kata08-conflicting-objectives/)

Note:

I solved the kata08 (by Dave Thomas) thinking about the readability of the code, in fact at the end was readable but really slow. To easily improve the performance I used the Set data structure instead of simple array to check the inclusion of the words (see Combiner class). Now it is very fast too.

How to run it:

ruby find_words.rb

How to run the tests:

bundle

rspec
