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: 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 !!
Example Output: negative

Example Input: Absolutely love it I wanted to fell that wall up because it was empty and I love the way it turned out ended up getting some cheap frames from dollar tree to put up because the taped pictures started to fad and bend it turned out amazing
Example Output: positive

Example Input: Very fast delivery, can't wait to install and use it, didn't disappoint me, very good. The warm wind quickly blows my hands. The machine is not big but the drying speed is very fast and it only takes a few seconds to complete.
Example Output:
positive
