Example Output: 5

Example Input: This is my fourth order of these pork rinds and I'm not sure what's up, but something's really amiss.  The bags are leaking some kind of grease and don't fluff up during the microwave process.  I used to love these, so hopefully this is just a bad batch.  If not, then Lowrey's needs to look into this and fix whatever has happened to a once great snack.
Example Output: 1

Example Input: I had bought Pocky when on vacation and enjoyed it but living where there are no Asian stores I have to shop on the internet. The guys in the family seem to like it better than the ladies for some reason. For a bit of insanity, search for Pocky commercials on youtube!
