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.

Input: Consider Input: Well I received this product Monday, it’s friday and won’t turn on anymore. It was wonderful for 4 days, but like I didn’t spend 30-40 bucks on this for it to stop working. I’d like my money back, considering my old heating pad lasted 3 years.

Output: negative


Input: Consider Input: Love the product but sellers need to pack it properly. One bottle's cap was destroyed and the product was all over the box and the other bottles. I lost about 50% of the product in one bottle so instead of a deal, this turned out to be an expensive item. Simple fix - tape the tops down. Wrap vertically - not horizontally.

Output: negative


Input: Consider Input: I've tried a few different whitening products which are not only quite pricey but don't actually give me any results and on top of that are full of chemicals; after only a week of using this product I've definitely noticed my teeth to be whiter, not that much but for the price and for the time it is worth trying it. I would recommend it.


Output: positive
