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: Live in TN. Bugs galore. ONLY thing I recommend, is that you safety pin it at the top of your hat so it doesn't slide off when you bend over. Due to ticks in our area, I spray it all over with DEET spray before putting it on when I'm clearing brush on the side lot. Lots of room, so if you're a big person, this will fit. Great Price/Value!
Example Output: positive

Example Input: My cats are indoor, but I keep the windows and doors open, so fleas do have the ability to get in the house. One of my cats was starting to show symptoms of having fleas, and I opted to try this vs a visit to the vet to tell me he has fleas. Did some research, and gave this a try. I'm still on the first application, but flea issue has subsided. Also, not as smelly or greasy as other flea medicines.
Example Output: positive

Example Input: I used two pods at the beginning of the summer and they bloomed beautifully, all summer long. However, the last 4 that I've put into the unit, did nothing. Not even a bud.
Example Output:
negative
