Example Input: your head will split open and ooze goop after reading this . All I can say is pass me some aspirin. This is a dozy of a bad novel. As it says on the dust jacket, a Supreme Court law clerk grabs a petition and ends up becoming deceased. Its up to the brother to uncover the truth by finding the real killer who had let a poor black man rot away for a crime he did not commit. At the same time the brother contends with mysterious bad guys out to get him and stop the unearthing of the evidence. Not only does he deal with his family, but his brothers friend, a sexy young law clerk herself and the duplicity on the bench she works for.    And that's only the start of the plot.     Its really pretty bad, it descends into mired pretensions and goofy resolutions. The characters are so shallow that you are left with little notion of who they are except for a faint nasty after taste over their conceded ways. Baldacci is along with James Patterson and Dean Koontz one of America's worst authors. If you want an author who writes on a similar vein to this, try one of Harlan Coben's last four or so stand alone thrillers with out the character Myron Bolitar in it. Or for a more sophisticated read, look for Denis Lehane, he wrote the amazing Mystic River, but his PI series located in Boston is pretty good as well.
Example Output: NEG

Example Input: A book full of examples of how NOT to write perl . I couldn't resist the title, so I got this book. Unfortunately, I cannot reccommend it to people who want to learn to write better Perl, execpt as a source of examples of the mistakes you should avoid.    For example, in one of the earliest examples, the authors uses "return undef" in a situation where the return value of the routine is assigned to an array, to indicate the routine didn't find any of whatever it was looking for. Unfortunately, this is a mistake, the correct code would be to use "return;" all on its own. The correct solution produces an empty array or interim values; the mistake creates an array containing one element, 'undef'.    There are a number of similar mistakes which indicate the author is in over his head, writing things he doesn't understand; the editors know even less about the matter; and the code was never tested and verified for correctness.    If you want to learn Perl, get "Learning Perl"; If you want to improve your Perl, get "Intermediate Perl.    To
Example Output: NEG

Example Input: The Best Of Catron . I remain firmly in agreement with my good friends, who wrote the critique below.  The very best of Catron's texts, this book inspires immediate enthusiasm and, therefore, interaction with the author.  I'll hang onto my  original hardcover copy until it turns to dust, and continue to use it  while both writing and teaching.  An inspired text
