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: For hours I have tried to figure out this machine. It finally got the best of me. It is being returned. I can't figure out how to bind 8 1/2 x 11 size paper. It leaves a half punched hole either at the top or the bottom of the paper and the combs they give you are too long for this size paper as well.
Example Output: negative

Example Input: Suit is starting to fade after a few wears. After the 10th wear the suit is almost bleached out. I liked that is was fully lined but now the suit looks terrible.
Example Output:
negative
