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: This item arrived in the mail a MESS! When I opened the package, I stuck my hand into goo. Not only was the lid not screwed on properly, but the container was actually cracked! See pictures! And it says “no returns”. It’s unusable! All of the liquid is in the envelope or dripping off the bottle
Example Output: negative

Example Input: At first the fan was great, very quiet. we have had it for just over a year now. recently two of the three fans quit working. we dont use it much so we were surprised to see it acting up. We also never received a remote control as advertised
Example Output: negative

Example Input: Following retinal surgery (for a detached retina) and subsequent cataract surgery, I experienced eye strain when reading. Systane Complete provided near immediate relief of my eye-strain. While Systane Ultra is great for my general dry-eye condition (in both eyes), Systane Complete really worked in relieving eye strain in my primarily affected eye .
Example Output:
positive
