In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: So far we really like it! We need to buy another since this one is short, but we are pleasantly surprised with how well this hose works. There's no complaint here on leaks. It does drip very slightly but our regular hose was much worse, a constant leak ( we have very hard water) so we think this is a great change!
Example Output: positive

Example Input: Lauren Carr really impressed me with The Last Thing She Said. I loved how she wove characters from previous books and series together, and tied them into a cold case mystery. The humor in this book is laugh out loud. There are plenty of cameo appearances by Gnarly, Sterling, Storm, Thor, Traveler to keep the animal lovers happy. The references to Robin Spencer, Mac Faraday, Archie, the Geezer Squad, Chris Matheson and his family all kept me happy. The book is a gem with so many facets. I loved the mystery of Mercedes Livingston and her husband, the romance, the twists, and of course the canine crime boss!
Example Output: positive

Example Input: Unit switches off whenever it feels like it. No matter how long you set the timer for, it will randomly just turn off and then yogurt cultures get cold. The dome is also shaped to have condensation drop into the center glass container. Pretty poor design. The rest of the condensation runs down the dome, and instead of draining into the base unit, it just runs onto your countertop. Can't wait to send it back !!
Example Output:
negative
