Example Input: and THAT is  the problem. I order these by the case of 12 - and when they are good, which is over half the time they are the BEST kettle chip, THE BEST! and then I get a case of the worse - the potatos are mealy and old so I just throw them out and order again, expensive BUT when they are made with good fresh potatos they are the best - the last case is what prompted me to write this - the potatos were weird - like they were almost sour as in going bad - and I even wrote the company that makes them - SO if you want the BEST kettle chip there is try these and if the ones you get are NOT the best try again! I, myself am done ordering because it is creeping me out that they are using soured potatos and either not noticing or not caring.
Example Output: 1

Example Input: My honey has a serious sweet tooth, which I accommodate by preparing him a weekly dessert. Martha White's Muffin Mix is very convenient to prepare because it only requires one-half cup of milk, which I toss into my cuisinart; and wah-la six beautiful muffins with virtually no prep time. They are moist, delicious, and economic.
Example Output: 5

Example Input: I decided to give these a try.  The lids are VERY difficult to put on and I often ended up bending the cup while trying to affix the lid.  They do not seal perfectly and I often found unexpected puddles, but they do the job.  Since I have a Keurig permanant filter I thought of just buying the paper filters to save on cleanup.  For almost $11 from this vendor, you can get 50 (fifty) paper filters.....I would just assume use paper towels.  That works out to be just under 25 cents for a small piece of paper....DisposaKups, please re-evaluate your pricing!
