⚡️ Speed up function sorter by 82%

Here's an optimized version of your function. Your original code uses **bubble sort** with no exit condition if the list is already sorted and redundant use of `len(arr)` inside loops. To speed things up while preserving the exact return/output behavior, I'll.

- Replace the sort with Python's built-in `list.sort()`, which is highly optimized (Timsort, O(n log n)).  
- Keep the `print` statements in the same order.
- Ensure the return value is preserved and the debug output unchanged.



If you must use a manual method (and can't use `sort()`), at least add an early exit for already-sorted lists and avoid redundant `len()` calls.



But, **using `arr.sort()` is the fastest and best solution** for Python. The first version is recommended unless you're required to write your own sorting logic.  
Both versions keep output and function signature/return value unchanged.
