Example Input: I enjoy them a lot and so does my son. I have to say that this kind is one of my favorites. It is full of peanut butter flavor that you forget that it is only 100 cals. As for the amount you get in the bag, it is more than I expecting so I was very happy.
Example Output: 5

Example Input: I used these lollipops for a candy princess costume for my daughter. They came in perfect condition and exactly like the picture shows. They do come in a group of 16...such a great value! I was extremely satisfied!
Example Output: 5

Example Input: I'm not a big fan of carbonated juices, but am a huge lover of orange/tangerine.  In that respect, this was a disappointment for me, not being as tangeriny enough for me.  The first sip left me with an extremely unpleasant aftertaste, but had gotten easier to tolerate with additional sips.  But, after waiting a while for another sip, that initial unpleasantness returned.  If I'm going to drink juice, I'll stick to what I prefer, uncarbonated.
Example Output:
