## Problem:
We need to change the regex ```countNonWhiteSpace``` to look for multiple non-whitespace characters in a string.
## Solution:
```js
let sample = "Whitespace is important in separating words";
let countNonWhiteSpace = /\S/g; // Change this line
let result = sample.match(countNonWhiteSpace);
```
## Explanation:
We use ```\S```, and this pattern will not match any of: whitespace, carriage return, tab, form feed, and new line characters. So we find all matching non-whitespace characters.
