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: We loved the unscented pods but this vetiver scent is intolerable. It smells like mildew to me and overly flowery to my husband. Now we've got 100+ pods no one can bear the smell of. I had to rewash everything we washed with them. So bummed.
Example Output: negative

Example Input: If you're thinking of starting, have started or even have been eating Keto, this book is a must have! This is exactly what I was looking for when I started!
Example Output: positive

Example Input: This is easy to use and comfortable. The heat doesn't last that long and the scented smell is so terrible that I can't even keep the eye mask on that long.
Example Output:
negative
