* | |
* Use the existing `test` variable and write a `forEach` loop | |
* that adds 100 to each number that is divisible by 3. | |
* | |
* Things to note: | |
* - you must use an `if` statement to verify code is divisible by 3 | |
* - you can use `console.log` to verify the `test` variable when you're finished looping | |
