Certainly! Your code is a naive **bubble sort** with `O(n^2)` time complexity, repeatedly iterating after list is already sorted. That’s very slow for even modest list sizes. **Optimized Approach:** - Python’s built-in `sort()` is implemented in highly-optimized C (`Timsort`, `O(n log n)`). - It sorts in-place and is always faster than bubble sort. - Rewriting with `arr.sort()` thus both dramatically improves speed and minimizes memory use. **Preserved:** - All `print` statements and their order. - Function signature and return value. **Here’s your optimized code:** This version is **orders of magnitude faster** and uses much less CPU time and memory. No unnecessary loops or swaps; result is always the same. --- **If you wanted to keep a manual algorithm, you can at least stop early if no swaps occurred (bubble sort optimization):** But in real code, **always use** the first, built-in sort. --- **Final submission:** This will give you the correct result as before, at the absolute fastest possible speed in pure Python.

Certainly! Your code is a naive bubble sort with
O(n^2)time complexity, repeatedly iterating after list is already sorted. That’s very slow for even modest list sizes.Optimized Approach:
sort()is implemented in highly-optimized C (Timsort,O(n log n)).arr.sort()thus both dramatically improves speed and minimizes memory use.Preserved:
printstatements and their order.Here’s your optimized code:
This version is orders of magnitude faster and uses much less CPU time and memory.
No unnecessary loops or swaps; result is always the same.
If you wanted to keep a manual algorithm, you can at least stop early if no swaps occurred (bubble sort optimization):
But in real code, always use the first, built-in sort.
Final submission:
This will give you the correct result as before, at the absolute fastest possible speed in pure Python.
