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: Great helmet! Nice fit and great adjustments to get right fit. It’s very comfortable on and doesn’t slide around. Has good amount of padding. Great buy for the price.
Example Output: positive

Example Input: Huge disappointment that caused nothing but grievances. This TV only lasted 21 days. This Lemon TV quit showing a display out of the blue the day before Christmas Eve! What timing! Guess what I did for Christmas? Not surprised this TV is discontinued. It's a glorified paperweight. Element should stick with making cardboard boxes. I never write reviews but this was a special case. I would avoid buying any Televisions through Amazon. Period. Avoid the hassle and get a name brand TV like a Sony or Samsung. The few extra bucks is worth the peace of mind. Today as I write this, UPS just tried to deliver the same TV I sent out to return for a refund. Didn't bother ringing the door bell with the return label on Tuesday. Welcome to the Holiday Season. Incompetence with both Amazon and UPS. Now I'm going to have to wait probably another week for my refund. If it's too good to be true, it probably is. Buy cheap, get cheap. Just buy a Sony. Don't buy a TV with less than a 4-Star rating and less than 200 reviews. Rule of thumb. P.S. Android is better. Happy New Year!
Example Output: negative

Example Input: With shipping and tax ,this cost me almost $30, for the most awful muffin I've ever had in my life... incredibly salty (despite no added salt to the mix), bitter, mushy texture.
Example Output:
