Jewels-and-Stones

LeetCode May Challenge Problem 2 Week 1 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

Example 2:

Input: J = "z", S = "ZZ" Output: 0

Note:

S and J will consist of letters and have length at most 50.
The characters in J are distinct.
