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: Well I would love to give you an actual review of this product but I have not received it. I have tried to contact wheel toppers without any success. I have also informed amazon of this and so far I have not gotten any help from them. I am for the first time disappointed in them as well
Example Output: negative

Example Input: Bought for preteen daughter. Easy to use. We put curl cream in hair while wet, then put these in her hair and kept them in over night. Curls looked great. No tangles when removing. Great quality for price. Delivered quick.
Example Output: positive

Example Input: This is a fantastic charger for the price. I just now found out that the iPhone 8 and onward can be fast charged with a USB-C PD charger. Paired with a good USB-C to Lightning cable the combo charged my iPhone 8 from 2% to 57% in 37 minutes. Towards the end of the charge- 90% onward...the charging speed is slowed- but this is normal for most chargers. If you are in a emergency situation or need your phone charged fast- this item will do it. Very happy with purchase.
Example Output:
positive
