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 use this weekly or even more. Cooking is a chore, so using the crock to make meals for the week is a plus. The item is nice to look at, so doesn't take away from the room, and easy to use. I'd recommend for anyone who is a lazy cooker like myself!
Example Output: positive

Example Input: I really like Pippa's writing. This sci-fi slash fantasy combination has me hooked. Cannot wait til the third book is released. Plot keeps you guessing about what challenge will come next, and how will the character grow with it. Please keep this series coming...quickly preferred. ;-)
Example Output: positive

Example Input: I bought two of these calendars - I had one sent to my daughter and bought one for myself. If my daughter lived closer I would pick it up from her and return both of the calendars. The quality is something you'd expect from the 99 cent store. The pictures are fine but the quality of the calendar itself is not what I expected.
Example Output:
negative
