Given the task definition, example input & output, solve the new input case.
In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.
Example: Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for our earth will find this hopeful
Output: POS
The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.

New input case for you: Only for first year, if u are doing indepth o-chem then this isnt it . Mcmurry is a colourful and over-generalized textbook that presents the most fundamental concepts of organic chemistry without fully elucidating on their logic. Mcmurry's style is to induce learning of 0-chem via memorizing of reaction mechanisms, and other trivial components. The only reason you should buy this book (same reason I did) is if your o-chem course is based on this; that being, this is your prescribed text. It is far too difficult to study organic chemistry with another textbook. However this may not be the case for this edition of Mcmurry. Organic Chemistry by Wade has the same chapter format, covers essentially the same thing but treats the fundamental principles with more depth; allowing the reader to appreciate the finer points of organic chemistry. One thing that irritated me the most about this book was that there is no appendix for IR frequencies of major functional groups, and mass spectra is barely covered. It is at best just mentioned...nothing more. Wade treats the interpretation of spectral data with more clarity and depth...something which is essential in second year chemistry. All in all this book doesnt even provide a good grounding in the basics. When it discuses KMnO4 oxidatation, that at least should be a review of redox. The chapters on Substitution and elimination reactions as well as further chapters in aromatic chemistry are satisfactory, but it is the basics that are lacking. I would suggest for first time o-chem students to consult Wade and compare it to the writing style of Mcmurry. Albeit Mcmurry is very nice and colourful, you will regret its lack of depth and its over simplification of organic chemistry. The book itself is supplemented with another spectroscopy book here in Australia, which suggests the severe lackings of this book. This has been inherent in it for the last three editions...Not too happy with it
Output:
NEG
