Input: Consider Input: Another fine book by the master . Poirot is given a case by his old pal Spence which takes him to a small village, where the fussy detective must unravel clues behind a crime in which the main  suspect has already been arrested and sentenced... Hercule's indignities at the run down boarding house he's staying at make up the bulk of the story's humor, but the mystery is great fun, too and I doubt anyone can guess the killer, unless you're paying amazingly close attention. The characters here are some of Agatha's most entertaining, and Mrs Oliver, with her uncanny intuition,  always makes a nice flighty side kick..

Output: POS


Input: Consider Input: Substandard Text or Reference on RF Electronics. . This is a required text for a graduate level RF electronics course I am taking.  I am very disappointed with this text.  There are multiple mistakes and misprints throughout.  It seems that the book was proofed by  someone who is not familiar with electronic symbology and notation.  There  are many instances where inconsistant notation will be used within a single  example problem!  The author is very short on many subjects and longwinded  on others.  This book makes for a confusing and frustrating read despite  the distinguished IEEE brand on the cover.  My professor even commented on  the sloppyness of the author.  I have had to buy additional books to  suppliment my studies.  This is not a good reference or text book....Coming  from someone who has read multiple technical text books...Beware of this  one

Output: NEG


Input: Consider Input: Disappointment . Highly disappointing. No substance. It was a book filled with references to other books. Wish I had bought one of those instead!!!


Output: NEG
