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: I purchased in June and hired an HVAC professional to install. After several calls to Nest support, it was determined that we had a faulty plate so we attempted to install the 2nd and again after several calls and a couple of hours, determined that that one wouldn't hold its charge long enough to install. In both cases, the window to return them had lapsed so I am out of $400 plus and then had to buy a regular thermostat to boot! Lesson here, do not buy this product until you are ready to install it!
Example Output: negative

Example Input: Perfect as a personal item. NOT considered a carry on and you won't be charged for it! Wonderful when flying certain carriers that charge for everything!
Example Output: positive

Example Input: Absolutely no cords came with it! Seriously! Are they supposed to come with them? I felt it was standard. Here's your printer have fun running power to it it with no cords! Wtf!!!
Example Output:
negative
