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: Would definitely not recommend!!! Although the actual material that the bag is made of seems to be of good quality, the zippers are cheaply made. The zippers on my bag just won’t stay closed. It has split open numerous times, spilling all of its contents. Imagine the frustration having to pick everything up with 1 hand as you hold an infant with the other arm.
Example Output: negative

Example Input: These pants are awesome. They protect your legs very well for welding. If you use your knees for low level welding, brick work, tiling, carpets or roofing, your knees will wear out before these pants do.
Example Output: positive

Example Input: Do not buy these if you intend to use them in HomeKit, they consistently go off line. As a home automation device this one has along way to go. I should have bought Lutron.
Example Output:
negative
