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: Look out. I’ve used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn’t going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.
Example Output: positive

Example Input: Company sent round knob and not the lever as advertised. Company told me to uninstall to send back instead of sending me the correct lever instead offered me 20 rebate, smh smh
Example Output: negative

Example Input: Adhesive completely gave out within 8 days of application, just fell off phone and won't adhere now. When it was on phone the glare off of this was horrible. Phone was almost unusable in car or outside because glare obscured phone. Would not have purchased if not for the "Amazon's Choice", feel like Amazon should refund everyone who purchased this especially since they have since removed the "Amazon Choice" designation. Horrible product give us our money back.
Example Output:
negative
