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:
Unit switches off whenever it feels like it. No matter how long you set the timer for, it will randomly just turn off and then yogurt cultures get cold. The dome is also shaped to have condensation drop into the center glass container. Pretty poor design. The rest of the condensation runs down the dome, and instead of draining into the base unit, it just runs onto your countertop. Can't wait to send it back !!

Ex Output:
negative

Ex Input:
