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.

Ex Input:
Produce pieces did not match up. Asked for new product, they said they sent but it never left the warehouse. Asked for refund, they subtracted shipping which was substantial, had to make Amazon cover the shipping costs. Customer service for this company is only available in the middle of the night. Not worth the few dollars saving. Ordered off Josh and Main.

Ex Output:
negative


Ex Input:
These bracelets work fantastic. I can't see mosquitos around me while i wear them. So great experience for me as a terrible mosquito magnet. Thanks. I would buy again.

Ex Output:
positive


Ex Input:
I got it today. I'll put it on the front porch and the back yard and the garbage can. It's very good. It's light, sensitive, convenient, very practical.

Ex Output:

positive
