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: Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.
Example Output: negative

Example Input: Loved the shirt. Fit was as expected, not too tight or loose. First time I wore it, after a few hours, I noticed that there were holes where the stitching was across the front of the shirt. Very disappointed as I really liked the shirt.
Example Output: negative

Example Input: Finally sheets that actually fit the Cal. King and are deep enough for a pillowtop mattress. Getting 4 pillow cases was a huge benefit because when you have a king you always use at least four pillows, a practical and nice looking set of sheets
Example Output:
positive
