Example Input: Switch Orange Tangerine is ok but not what one might expect.  First of all, there is more apple and grape juice in here than orange or tangerine (this will not be a surprise if you are familiar with the other flavors as that is also true with them).  Switch basically is carbonated juice.  The taste isn't a bad and it is supposed to be healthier than soda (which can be debated).  It is a reasonable drink for snacks but if you are going to need several if you are actually thirsty.
Example Output: 3

Example Input: I've tried a few different flavors of Switch and this is my least favorite. (My favorite is the cherry.) Unfortunately because I didn't enjoy this flavor I didn't find it as refreshing as the others.  I quickly handed it over to my son who does like kiwi berry flavors and he did like it a lot. Of course, since it contains enough vitamin C for a whole day, I felt just fine giving it to my child, too. No preservatives, no added sugar. I like the carbonated soda product a lot, just not this flavor.  However, the biggest flaw with this product is that it's too expensive in my opinion for the little cans you get. Rounds out to about $1 per can. Less than you pay often with a vending machine but twice what you pay for a flavored water or vitamin C juice pouch when you buy them in larger quantity. Not worth it. :(
Example Output: 3

Example Input: These jelly beans are wonderful.  They are smaller than regular jelly beans but that doesn't take away the flavor.  I would recommand these to anyone.
