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 bought these in Sep. and these racks burned and melted on the bacon. So you will have to throw away the food you have cooked and the racks. I cook bacon maybe 3 times a week. Do not waste your money
Example Output: negative

Example Input: Love the locks! Very easy to setup and 100% serve their purpose. I have a very curious 10 month old little girl who is starting to get into anything and everything which was why I purchased this item. Very pleased at how well they prevent her from getting into things she shouldn't be getting into.
Example Output: positive

Example Input: This will become my go to pack, definitely the best pack I've owned. Lots of pockets and lots of room for a day pack, and well constructed. Not cheap, but I won't be replacing it any time soon.
Example Output:
positive
