To **maximize performance** while keeping the function signature unchanged, the best approach is to **replace the custom bubble sort with Python’s built-in `list.sort()`**, which is highly optimized (Timsort, O(n log n)). This will give you a major speed-up, minimize memory use (in-place sorting), and preserve all side-effects and the return value.

Here’s the optimized version.



### Justification.
- `arr.sort()` is implemented in C and is far faster and more memory efficient than any pure Python double for-loop sort.
- All output/return behaviour is identical.
- No additional memory is needed (in-place sort).
- The `print` statements are preserved as in the original code.

**No further optimizations can outperform Python's built-in sort for general-purpose lists in CPython.**

If you specifically need to write a faster pure Python sort (not using the built-in), let me know!
