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: Been a long time since a book has held me so captivated & enthralled. Deep, exciting, moving & Inspiring, Mitchell's command of the English language is unparalleled. Never wanted this book to end.
Example Output: positive

Example Input: Clip is smaller than OEM, they also don't expand nearly as well as the original and don't have a relief cut into them for easy removal... Half the installed clips have fallen out in less than 500 miles so I guess that relief isn't really needed. These are far less superior that the OEM clips. Buyer beware, you get what you pay for...
Example Output: negative

Example Input: This smart plug works exactly as described. This is the second set of 2 smart outlets I have used for several months. Mostly used to control lamps and Christmas lights, the outlets are simple to add to the free Smart Life app. The schedule function triggers on/off of the outlet exactly when set. Multiple methods exist to override the schedule and also an on/off button on the outlet itself allows local control when needed.
Example Output:
positive
