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 ordered this, got a cool color pink vinyl, played the b-side and it skipped several times. Well, bummer. I called amazon, got a replacement sent, same color vinyl arrived with the same skipping in the same places. Had another replacement sent. Same color, same... you get the point.
Example Output: negative

Example Input: Don't waste your money on these. Sound quality is good for the price, but the headband broke within a month. I am extremely careful with my electronics, and barely even used these things... maybe a dozen or so times before the headband broke. Too bad, I thought I finally found a quality pair of BT headphones at a decent price.
Example Output: negative

Example Input: I hardly ever leave reviews but I've been using this product for almost a month and my skin has improved TREMENDOUSLY! My pores have shrunk, my skin is glowing and my hyperpigmentation/old acne marks have improved. I've never been one to leave the house without foundation and I'm still a little self conscious about that but lately, I've found myself heading out the house without wearing any and feeling great!! I started using it only once a day, but now I use it both day and night and that's when i started seeing the real changes. It's a must try !
Example Output:
positive
