Hi Chris, really like this example. I have a couple of pieces of feedback since I tried to run it and encountered issues. Line 19 needs to be str = i instead of str += i. Since str is started as a string, I get "no implicit conversion of Integer into String" when I try to add the i. Also, str.blank? works if you are in an ActiveSupport context. Otherwise, str.empty? is available.

Found this very useful, thank you! If you have any more patterns wisdom, please bring it on :)

Thank Chris, I found this useful.
