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: DON'T purchase candles or BREAKABLE items from Amazon. They don't bubble wrap or protect products. You pay high shipping fee, wait long periods and receive BROKEN products. DO NOT TRUST AMAZON..YOU'VE BEEN WARNED !!
Example Output: negative

Example Input: I bought these to use around the house instead of carpet slippers as they were making my feet sweat, and after being in work boots all day a bit of fresh air would not go a miss.
Example Output: positive

Example Input: I open the blue ink and before I could put it in the printer it dripped on computer chair, my pants and my carpet. I had to rush and get some alcohol that removed most of the ink from my chair and carpet. Really disappointed. Cannon is always saying to order authorized ink and when I did it leaked all over. I would have been better off ordering a different ink cartridge rather than the authorized Cannon ink. Less problems.
Example Output:
negative
