Subject: How to create an Array in a Hash

Hi,

I am new to Ruby and am working on Anagram. So in anagram for the input
below

# input: ['cars', 'four','scar', 'creams', 'scream', 'scream']

I want an output like this
# output: [ ["cars","scar"],
#           ["four"],
#           ["creams", "scream", "scream"] ]

But i am getting an output like
# output: [ ["cars","scar"],
#           ["four"],
#           ["creams", "scream"] ]

because of Hash property.

This is my code.

sorted_words = Hash.new(0)
words.each { |word| sorted_words[word]=word.downcase.chars.sort { |a, b|
a.casecmp(b) }.join
}
sorted_hash = {}
sorted_words.each_pair do |key, value|
  (sorted_hash[value] ||= []) << key
end

anagram_array = sorted_hash.values

Please advice me (with some code) how to solve this. Thankyou for taking
you time out and helping with this amazing language
