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: Product was exactly as described, worked like a charm. Good quality material does what I want to do, and looks great. I would like to see a few more aluminum crimps in the bag to do multiple loops on the cable in the future. Overall great product.
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: I bought 2 of these in hopes of what all other reviews said.. Charged them on the original charger and went to fly. Both of them within 5 mins dropped down immediately. Went from full whem I lifted up. Accelerated forward about 30 yards and the low battery warning popped up. Brought it back to land and when touched the ground it said they were full again. I requested a refund and will be purchasing the originals.
Example Output:
negative
