In fact, I have done a modification to my version, to generalize that
thing: instead of assuming we have keys from min to max I actually get
an array with all the possible key lengths with:

key_lengths = letters.keys.map {|x| x.length}.uniq

and then modify the min_length.upto(up_to) with key_lengths.each

which optimizes the loop for arbitrary key lengths... but haven't been
able to test my code yet.

Thanks, I'm in complete love with the language, and the community is
great. Ruby Quiz is a great tool to learn.
