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: I have been using this exact brand and item but bought at Ulta. They are great. I got months of wear out of them. When they no longer carried it I ordered it from here. I got 2 pairs. They both did not stick to my skin at all. They couldn't be worn.....fell right off. I found them at CVS and did not have a problem with those. This was supposedly the same exact product. I'm not sure what to think but I would not recommend buying from here.
Example Output: negative

Example Input: Great book...really many tasty recipes are there in this book..which keeps you fit and healthy..I like this helpful guide very much..author explained very well..highly recommended
Example Output: positive

Example Input: We ordered this for work and once it got placed on the door you can barely see it, the white border somehow needs to be brighter, it's very dull and almost transparent.
Example Output:
negative
