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 haven't used these products yet, the raincoat used before was very heavy. It's very inconvenient to put on. So I tried this raincoat, it feels great to put on. There is no sense of obstructing action. When I opened the package, I found a variety of raincoats in different colors, each of us can choose the color we like. I think we can take it with us on the field trip. Because it was raining hard days ago, it was I who carried a raincoat like this I won't get caught in the rain, I don't even feel it. It's a great feeling. A raincoat is long enough, it won't get your knees wet. That's not what other raincoats can do. So I suggest you take a raincoat like this. It won't take up your space and it will bring you convenience.
Example Output: positive

Example Input: I’ve used this product two times. The first it was really nice to sleep on and no air leaked, the second it deflated before we even laid on it to sleep. It’s too late to return it now or else I would. I do not recommend this product.
Example Output: negative

Example Input: LOVE this color! It’s perfect. When I got it, it did look way too light, but after applying it - it’s perfect. Looks even prettier in person. The two fingers with the lighter color in the picture are after dusting off the excess powder - the index finger (darker blue) is after applying seal protect - it’s just perfect and is the final shade. It has lighter occasional flecks that make it resemble stars - it’s beautiful. Definitely recommend!
Example Output:
positive
