If what you explain is right, how come I get 'AA' when I add a line 
here:
def table(array,word_size=1,word='')
  hash_table=Hash.new(0)

  array.each do |e|

    if word_size==1
       puts  "#{word+e}"############# add a line to see if 'AA' is 
created
             hash_table["#{word+e}" ]=0

  else
      table(array,word_size-1,word+e )
  end
 end

return  hash_table
end
