Subject: Re: How to create an Array in a Hash

Ok, I did what you proposed

sorted_words = words.uniq.group_by{|w| w.downcase.each_char.sort}.values
p sorted_words

results in

[["cars", "racs", "scar"], ["for"], ["potatoes"], ["four"], ["creams",
"scream"]]

Its way simpler than what i was doing previously but still the result is
the same. I do not have two scream
