when using this method, I got an error message that says:
poem_program2.rb:7:in `block in <main>': undefined method
`reverse_words' for main:Object (NoMethodError)
  from poem_program2.rb:7:in `each'
  from poem_program2.rb:7:in `<main>'

Is there another way to approach the method using string and how would I
go about it to reverse and go from last line to first in reverse order?
