/**
***********************************************************
771. Jewels and Stones
***********************************************************
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.
*/
// let jewels = "aA",
// stones = "aAAbbbb";
let jewels = "z",
stones = "ZZ";
let jewelsLength = jewels.length;
let count = 0;
let stonesLength = stones.length;
for (i = 0; i < jewelsLength; i++) {
let current = jewels.charAt(i);
for (let j = 0; j < stonesLength; j++) {
if (current == stones.charAt(j)) {
count++;
}
}

console.log(`count = ${count}`);
