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: After the third use it did not charge up any more. Ok if you want a disposable charger to throw away after only a couple of uses. It worked ok for the three times that I was able to use it. However it did not charge my phone to 100%, only to 80% before it lost all of its charging power. I did not have a problem plugging it in to my Pixel 3 with a case on it. But that doesn't matter now as the charger does not work. Seriously, do not purchase this product. Other one star reviews can attest to the same fault.
Example Output: negative

Example Input: Not water tight...? moisture inside lenses after only a couple weeks of installed use. Was sent replacement, and it did the same after only a couple weeks. Then after about 4 months half of the lights stopped working.
Example Output: negative

Example Input: These headphones work great for my Xbox 1. We are a gamer household and always looking for more headphones since We like to have our own. These work great with current Xbox 1 games. We played Fortnite with my nephews in another state and could hear them clearly. It may take a minute to figure out the mute concept if you are not familiar with headsets, but we had no problems.
Example Output:
positive
