This is like your program 1, but just slightly different. You will need to
write the reverse_words function yourself, try writing it separately from
the rest of the program, and then when you are satisfied it is correct, use
it as shown below.




def reverse_words(line)
end

contents = File.read("poem")
puts contents

my_file = File.new("poem")
line_array = my_file.readlines()
line_array.reverse!
line_array.each { |line| puts reverse_words(line) }

my_file.close
