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’m very sad with the quality of this product, is the first time to try to print something. I was so frustrated and all was the filament. The printing look bad, like filled of bubbles and no definition. Is not the money is the frustration. I blame the printer, the calibration of the bed, the temperature. Again. Sad. Nothing else to say.
Example Output: negative

Example Input: It is deceiving in that it did not come with the portable charger and cord as it advertises. We were thoroughly disappointed when the package came and that was missing. The whole point of my 10 year old son wanting the backpack was for that reason. That being said, if you like the backpack the. You will be happy. My son has been in school for 2 months and no damages from the backpack can be sighted.
Example Output: negative

Example Input: Looks exactly as pictured and fits my pillows perfectly! Was able to get both pillow cases on without any threads snapping, so that says a good bit about the stitching quality! Will definitely buy from the brand again when looking to freshen up the look of my house!
Example Output:
positive
