Hints and Clarifications

• Regular expressions are not necessary all the time

• stringr functions are handy

• str_view() vs str_view_all()

• Step 3: Any time you see the word “ugh”, with any number of h’s, followed by a punctuation mark, delete this.

  • ugh, ugh! ughh! ughhhh should be deleted

• Step 4: Replace all instances of exactly 2 a’s with exactly 2 e’s.

  • “baa” –> “bee” but nothing should happen to “baaa”

• Step 6 Every word that ends in b, change that to a y. Hint: punctuation!

  • either “b!” or “b” is changed to y, no need to keep punctuation

• By the end of step 7, you should see individual words that make sense.
