Example Input: These notepads are difficult to write on with a Fisher Space Pen. It does work, but the writing is rather splotchy. Works great with gel ink (but may smear), and is alright with regular ballpoints. It repels water on the surface, but the edges allow water to seep in, so underwater writing may not be a good idea.
Example Output: 3

Example Input: I was a loyal TurboTax user until they no longer supported my Mac operating system. I figured I'd give this software a try. It's almost same process as TurboTax but cheaper. Just follow the questions, fill in your info (or import it), and everything is calculated.I read a review about the update that doesn't update. It's true but a minor annoyance. A very good tax software alternative.
Example Output: 4

Example Input: Putting it quite bluntly, this book was just no good. By the end of the book I wasn't even sure who the murderer was. I know his name but there were so MANY names, I'm not really sure who he was or how he fit into the story. There were dozens of names of people connected to the story. To complicate matters even more, sometimes they were called by their first name and sometimes they were called by their last name. I had a very hard time remembering who was who and what part they played in the story. In the end I just gave up on trying to keep every name, first and last, straight. The author wrote this book like it was a novel with imagined conversations, thoughts, and movements. It was enough to make a real true crime buff crazy! It all sounded so fake and made up! With a complexity of characters and the imagined conversations it was just not a fun book to read. Also, there was NOTHING about the trials other than the results. Had this been my first true crime book, I probably would have never read another one. I have read hundreds and this was one of the worst. Friends often want me to recommend a "good true crime book" to them. This will NOT be one of my recommendations! There was nothing about it that I enjoyed. No good!
