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: 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've been looking for a nice casual dress like this for a long time and finally found it! It fits me perfectly and I'm really happy I've accidentally trapped on it!
Example Output: positive

Example Input: The bottle was unsealed in the package, nozzle and top were not screwed on and upon arrival almost all the liquid had spilled out into the plastic packaging. Absolute mess.
Example Output:
negative
