Cyber_haiku_dictionary Challenge Solution

for arg in ARGV
   file = File.open(arg)

   file_data = file.read

   hash = eval(file_data)

   fixed = hash.sort_by { |num, word| num[/\d+/].to_i }

   sanitize = fixed.map {|row| row[1]}

   puts sanitize.join(' ').gsub(" \\n ","\n").sub(" \\n","")
end

Solution Notes:

After the .sort_by method, the hash has now become an array for some reason. Since the hash has been turned into an array, we used the “map” method to extract the 2nd column values using row[1] to produce a single row array that has the each row value as an element in the new array./ The single row array is then separated by the .join(‘ ‘) method which as delimeted by a space and sanitized further with the .gsub and .sub methods.
