⚡️ Speed up function sorter by 640,814% in bubble_sort.py

[codeflash-ai]

📄 sorter() in bubble_sort.py

📈 Performance improved by 640,814% (6,408.14x faster)

⏱️ Runtime went down from 93.9 milliseconds to 14.7 microseconds (best of 1135 runs)

Explanation and details

To optimize the given sorting function, we can replace the bubble sort implementation with Python's built-in sort method, which uses Timsort, a highly optimized sorting algorithm.

Here's the rewritten function.

This will significantly increase the efficiency of your sorting function.

Correctness verification

The new optimized code was tested for correctness. The results are listed below.
