Today we are going to track the movement of smoke in a forest that has started catching on fire. We are given a 2-dimensional array that describes the shape of the forest and the starting point of the fire. At an index in the array can be either a "." to represent a tree or a "m" to represent a mountain. A tree can catch on fire and spread the smoke, a mountain cannot catch on fire. We would like to create a function that goes from the starting point of the fire and replaces any "." or tree with an "s" to signify smoke.

Given an array of strings, group anagrams together.
/**
* 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"
**/
// Examples
Input: J = "aA", S = "aAAbbbb"
Output: 3
Input: J = "z", S = "ZZ"
Output: 0
