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: The shell is flimsy and brittle with flaps that don't sit flat and a shape that doesn't sit square. The design relies on single snap-button connections on each side and pop-out hangers for the fabric liner. To much glare for what I needed.
Example Output: negative

Example Input: Thanks for another great story line and giving the military experience to a woman! YES! Finally the woman isn't there just to can and care for the little ones. Although they can do that too
Example Output: positive

Example Input: This does not work. I used a big potassium pill and it did nothing. I read another review said break in half so I tried that and it still did not work!
Example Output:
negative
