    771 - Jewels and Stones.

    Easy

    You're given strings jewels representing the types of stones that are jewels, and stones representing the stones you have. Each character in stones is a type of stone you have. You want to know how many of the stones you have are also jewels.

    Letters are case sensitive, so "a" is considered a different type of stone from "A".

    Example 1:

    Input: jewels = "aA", stones = "aAAbbbb"

    Output: 3

    Example 2:

    Input: jewels = "z", stones = "ZZ"

    Output: 0

    Constraints:

    • 1 <= jewels.length, stones.length <= 50

    • jewels and stones consist of only English letters.

    • All the characters of jewels are unique.
