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: Worked 45 days and died. Asked for a replacement or a refund. Told it was outside of return period. I see no return period listed. Amazon is not able to do anything because of 3rd party SELLER item. I was ripped off. DO NOT BUY FROM BIG D DISCOUNT!!!!!!
Example Output: negative

Example Input: I bought this to test it out since I needed to buy several solar lights. The detachable solar panel was a huge plus. I left this out sitting along with another unit from a separate company for a few months I got busy/forgot these were out there. Well I went out today to install it and this unit is dead. I popped the battery compartment no seal in the lid. one of the batteries corroded. So Im going to see if I can bring it back to life with a little cleaning. for now 1 star because it died after a few months of rain.
Example Output: negative

Example Input: Great quality, really nice. Got money back for a shade that was bent in the shipping process. But a couple of weeks later a sticker came off of the bottom claiming there was lead in them!
Example Output:
negative
