⚡️ Speed up function sorter by 223,402%

Here's an optimized version of your code.

### Major improvements.
- **Use Python built-in sort:** The original code is an unoptimized bubble sort (`O(n^2)`), while Python's built-in `sort` runs in `O(n log n)` and is highly optimized in C.
- **If you must keep the in-place sorting and returning of `arr`, just use `arr.sort()`.**
- **All variable swapping is handled internally by Python efficiently.**



#### If you want to keep a manual fast sort (like quicksort), consider.



### Why this is faster.
- Removes unnecessary Python for-loops and variable swaps.
- Built-ins leverage C speed and tim-sort algorithm.
- **Behavior is identical:** sorts `arr` in-place and returns it.

If you need a manual algorithm for educational purposes (not recommended for production), I can provide a fast implementation (e.g., using quicksort or heapsort), but for 99% of use cases, the above is best for speed and memory!
