# --description--
Note that `applyFunction` can access `toNumberList` from outside of itself. This is called lexical scoping - inner functions can access variables from outer functions.
Now return `str2.replace(regex, "")` at the end of `applyFn`.
# --hints--
See description above for instructions.
```js
assert(applyFn('2*2fn(1, 2, 3.3)') === '4');
```
