### max_n

Returns the `n` maximum elements from the provided list. If `n` is greater than or equal to the provided list's length, then return the original list(sorted in descending order).

Use `list.sort()` combined with the `deepcopy` function from the inbuilt `copy` module to create a shallow clone of the list and sort it in ascending order and then use `list.reverse()` reverse it to make it descending order. Use `[:n]` to get the specified number of elements. Omit the second argument, `n`, to get a one-element list

```python
def max_n(lst, n=1, reverse=True):
    return sorted(lst, reverse=reverse)[:n]
```

```python
max_n([1, 2, 3]) # [3]
max_n([1, 2, 3], 2) # [3,2]
```
