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: Read all the great reviews, so bought this item. Instructions are extremely inadequate; could not figure out how to put together. Returned immediately.
Example Output: negative

Example Input: So bad. I feel like the dishes would’ve been more clean if I used nothing. Dishes came out dirty and filmy every time. Couldn’t even tell if I ran the dishwasher or not and was having to rewash every dish.
Example Output: negative

Example Input: Good case however if you have tendinitis or arthritis in your hands you’ll find it’s hard to get the on/off and volume buttons to respond. It takes a concerted effort to activate those buttons. The case is not too thick so I can still put my phone in my back pocket.
Example Output:
positive
