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: Never received the lights. Email said they were undeliverable? Which is odd because i received other packages from Amazon that day and someone was home all day. Ill look elsewhere.
Example Output: negative

Example Input: Literally not the same bag. No pocket for credit cards and keys, no side pockets for umbrella/water bottles. No mesh inside pocket. It's the same shape and color that I ordered with none of the features. So annoying, I ordered this bag to hold specific items during a flight TOMORROW, and now I have to rethink my options. Thanks for the quality control, Amazon.
Example Output: negative

Example Input: Did not lose any weight & I had horrible abdominal pain throughout. I took it for 3 weeks because I was hopeful. Within 2 days of stopping, the abdominal pain completely subsided. Very disappointing.
Example Output:
negative
