⚡️ Speed up function mysorter by 20,147%
The optimized code replaces a manual bubble sort implementation with Python's built-in `arr.sort()` method, delivering a **201x speedup**. **Key optimization:** - **Algorithm change**: Replaced O(n²) bubble sort with Python's Timsort algorithm (O(n log n) average case) - **Implementation efficiency**: Python's built-in sort is implemented in highly optimized C code **Why this is dramatically faster:** The original bubble sort performs ~14 million operations for moderate-sized lists (as shown in the profiler), with nested loops comparing and swapping elements repeatedly. Python's Timsort is: 1. **Algorithmically superior**: O(n log n) vs O(n²) complexity 2. **Implementation optimized**: C-level implementation vs Python bytecode 3. **Adaptive**: Performs even better on partially sorted data **Test case performance:** - **Small lists** (empty, single element): Minimal difference, both are fast - **Large lists** (1000+ elements): Massive improvements, especially for reverse-sorted data which is bubble sort's worst case - **All data types**: Works efficiently with integers, floats, strings, and complex objects - **Edge cases**: Handles NaN, infinity, and mixed numeric types correctly The optimization maintains identical behavior (in-place sorting, same return value) while dramatically improving performance for any list with more than a few elements.
