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.

Ex Input:
Produce pieces did not match up. Asked for new product, they said they sent but it never left the warehouse. Asked for refund, they subtracted shipping which was substantial, had to make Amazon cover the shipping costs. Customer service for this company is only available in the middle of the night. Not worth the few dollars saving. Ordered off Josh and Main.

Ex Output:
negative

Ex Input:
Great book if you bought an air fryer and want some more recipes!I just tried a few recipes, but it's really a good starter book for learning the initial use of your fryer.

Ex Output:
positive

Ex Input:
I'm running duel inverters plugged in reversed A/C direction on an outside solar setup. Each side is independent on/off. Smart app keeps track of solar generation via WiFi as a combined total. Smart app [not included] (Smart Life) WiFi displays daily/monthly usage as a total only.

Ex Output:
positive
