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 wear medium so i order medium but wayyyyy to big so i just decided to give it away n order small size instead but unfortunately it looks like an extra large just waaaayyy too big
Example Output: negative

Example Input: Looks nice out of the box. Charges quick and touch screen is very responsive. That is the end of what's good. App that the included paperwork directed me to install is from a 3rd party site. Once downloaded, my antivirus warned me that it was an adware program. I installed it anyways. I then tried to pair the watch with my Samsung Note 8 and it would not connect. Tried other apps and it still would not pair. Not a very smart smart watch. Will be returning.
Example Output: negative

Example Input: This will become my go to pack, definitely the best pack I've owned. Lots of pockets and lots of room for a day pack, and well constructed. Not cheap, but I won't be replacing it any time soon.
Example Output:
positive
