Example Input: By something else. This is the worst piece of machinery I have ever bought. Virtually impossible to cut any size tile on the diagonal. Typical imported junk!!!!!
Example Output: Negative

Example Input: Jack Higgins may not be running out of his fascination with modern weapons, fine dining, glamorous women or the IRA but he appears to be slipping on plot and character development. Sean Dillon makes Doc Savage and Dirk Pitt look like pikers. And this curious extension of gentlemanly methods for attempting to kill one another -- sending a crazed assassin and then both sides meeting later at the Savoy to exchange notes -- strains credulity.Higgins has done some first-rate work. Had this been published twenty-five years ago, this might have made a difference. It wasn't and it doesn't.
Example Output: Negative

Example Input: This is a workhorse table with a guarantee---how can you go wrong? Mine are used in a pottery studio where students can work on their clay creations. Owned mine for more than five years and can't even think of a problem with these tables. They clean up well and are very sturdy. I like the leg design because I have yet to stub a toe on these tables. Don't hesitate to get this line of products; you won't be sorry.
Example Output:
Positive
