Example Input: Every single one of my twelve cans were BADLY dented. This is a TOTAL waste of coins. DON'T BUY THIS ITEM!!!!
Example Output: Negative

Example Input: We have these suto delivered.  They are a great healthy sub for potato chips and the snack bags are a perfect size.  Great crunch and we enjoy all the flavors.
Example Output: Positive

Example Input: My favorite coffees are the big dark roasts like French, Italian, and Full City.  This K-cup dark roast has a big, bold flavor, but lacks balance.  The level of smokiness, bitterness, and acid are way too high, and the result is not enjoyable.  I liked the dark roasts. for the Keurig from Green Mt, Newman, and Donut Shop much more than this one.
Example Output:
Negative
