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: With only a couple of swims under my belt, there is a marked improvement in leakage and fogging. Comfortable on my eye socket/face and the goggles come with additional nose pieces. Product is 'hair friendly' and attractive. It took me a while to figure out the straps, but I 'get it now' and like them.
Example Output: positive

Example Input: I was sent 1 black docker pants - wrong brand - the other pair of haggar slacks(blue) fits great, I am giving the others (black dockers) away to charity
Example Output: negative

Example Input: Last night, I set out all eight traps using peanut butter as bait. Tonight the results are in: 8 traps triggered, 0 critters caught. That’s right, 0% effective. Unless you like providing safe haven for mice to snack, look elsewhere. These traps were a complete waste of time and money.
Example Output:
negative
