### 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 array
``` py
from copy import deepcopy
def max_n(arr,n = 1):
numbers = deepcopy(arr)
numbers.sort()
numbers.reverse()
return numbers[:n]
```
