Example Input: Kind of  a ripoff.  I bought the theater box instead of the 5 piece candy bar version and that turned out to be a big mistake.  Each box has only 8 or 9 pieces and they are randomly filled so you are not guaranteed even 1 piece of each flavor.  One box had 6 green pieces and 3 black.  A better value is 20 pack of the original 5 piece bar.  This theater box is sold by weight (4oz) and not volume.  The box is about 90% empty- Ripoff!
Example Output: 1

Example Input: I am fairly certain this is the same tea sold by Caribou Coffee.  I think I could be considered an addict! The flavor is so good - lots of cinnamon and slightly spicy because of it.  Price for 50 is good and less than I have been able to find it elsewhere.
Example Output: 5

Example Input: There is a warning for this package that it has things in it that cause cancel!!!  Why would you put cancer in your food?
Example Output:
