⚡️ Speed up function sorter by 19%

[codeflash-ai]

📄 19% (0.19x) speedup for sorter in src/bubble_sort.py

⏱️ Runtime : 1.01 second → 853 milliseconds (best of 9 runs)

📝 Explanation and details

You can optimize this sorting algorithm by replacing it with a more efficient sorting algorithm, such as Timsort, which is the default sorting algorithm used by Python's built-in sorted() function and list.sort() method. Timsort has a time complexity of O(n log n) which is significantly faster than the O(n^2) complexity of the original bubble sort.

Here's the optimized code using Python's built-in sorting.

This code does the exact same thing but much faster for larger datasets.
