* You're given strings J representing the types of stones that are jewels,
* and S representing the stones you have. Each character in S is a type
* of stone you have. You want to know how many of the stones you have
* are also jewels.
*
* The letters in J are guaranteed distinct, and all characters in J and S
* are letters. Letters are case sensitive, so "a" is considered a different
* type of stone from "A".
*
* Example 1:
* Input: J = "aA", S = "aAAbbbb"
* Output: 3
