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 am so disappointed with this product I was very pleased with my previous vivoactive I just wanted a different style of watch to look more feminine while still having a Garmin. And that is about the only good thing about this particular watch it's battery life is horrible any little bump will have the thing flying to a whole different screen I would never buy this product again
Example Output: negative

Example Input: Look out. I’ve used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn’t going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.
Example Output: positive

Example Input: Don’t do it. Just pass. Three of the five were broken and the quality was incredibly cheap. I bought these as a gift for a child’s birthday as she wanted fun craft supplies. I returned this promptly.
Example Output:
negative
