Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider Input: Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.

Output: Positive


Input: Consider Input: I am a complete Sudoku addict and am very disappointed with this book. The only reason I bought it was because I was desperate for more puzzles and it was the only one available at the store I was in. First of all, it costs $4.99 which to me, is way too much money when you can get a Kappa book for $1.99 which has better puzzles. Another thing that bugs me about this book is that some of the answer keys in the back don't match the corresponding puzzles. When I get to the difficult/Very Challenging ones in the back, sometimes I need a little help! But unfortunately, this book has quite a few errors in the answer section so when I've hit a dead end, it's over.I would recommend Kappa books from your local supermarket. This simply costs too much money for not mush quality.

Output: Negative


Input: Consider Input: In reading use comments about Yanni's album "If I Could Tell You" I noticed this author advertised his book. Regardless of the book's merits, I think it should be rejected due to the author being a shallow, inappropriate capitalist.PS I'm proud of myself for not swearing at Mr. Mcandrew in this post.


Output: Negative
