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: Bought this after reading good reviews. But it’s not water proof at all. If my son has even a little accident in bed, it goes straight to mattress. I don’t see a point in having this. So I have to purchase another one.
Example Output: negative

Example Input: Bought this for a 2017 Ford F-350. Terrible product. Followed instructions exactly. Vent shades do not sit correctly so that when you put your window up it keeps going back down. Returned them and the company Auto Truck Toys only refunded 50% for a restocking fee. Product doesnt work but you have to pay for the terrible design. DO NOT BUY THIS PRODUCT OR FROM THIS COMPANY. You would be just giving away your money. I give this product and company NO STARS. I had give it a star otherwise it wouldn't allow me to submit
Example Output: negative

Example Input: Well firstly the connector was completely wrong. But since I have a full functioning brain I knew I could take the connector off the old motor and put it on the new one. Works perfectly after some modification.
Example Output:
negative
