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.
