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 buying these candies for years and years, and now it is so convenient to buy them online. Great flavors. Love that the cinnamon has a "little burn" to it.
Example Output: positive

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: I bought another one of these with no back sliding cover and it was total garbage. Bad fit, scratched my Hero 6 just trying to get it in the case. THIS case is 100% perfect! Slides in easily, without rattling around. Back cover fit perfect... battery door opens easily... all buttons and lights easily accessible and easily seen.the lens area does cover the LCD slightly, but it's a small trade off to pay so that you can use standard size lens filters. I highly recommend this case as long as you don't have an issue adding a little weight to your GoPro.
Example Output:
positive
