Howdy,
New to Ruby and looking for some help.
I would like to prompt the user for input String of single [0 - 9 incl]
digits e.g 57
and convert these to word format and store as a single string e.g
fiveseven
What way is best to go about doing this.
Should I create a hash of {1 => "one".....} and then iterate through the
input, swapping digits that match a key with the key's value.
Thanks a lot

yes but... gsub is much easier

I'd rather use an array than a hash in this case:
>> numbers = %w(zero one two three four five six seven eight nine)
=> ["zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"]
>> 2009.to_s.gsub(/\d/) { |n| numbers[n.to_i] }
=> "twozerozeronine"
