⚡️ Speed up function sorter by 139,489%

The optimized code replaces a manual bubble sort implementation with Python's built-in `arr.sort()` method, achieving a **139,488% speedup** (from 3.65 seconds to 2.61 milliseconds).

**Key Optimization:**
- **Replaced O(n²) bubble sort with Timsort**: The original code used nested loops with O(n²) time complexity, performing up to 114 million iterations and 53 million swaps for larger inputs. The optimized version uses Python's highly optimized `sort()` method, which implements Timsort - a hybrid stable sorting algorithm with O(n log n) average case performance.

**Why This Works:**
- **Algorithm complexity**: Bubble sort's quadratic time complexity becomes prohibitively expensive as input size grows, while Timsort scales much better
- **Native C implementation**: Python's `sort()` is implemented in C and heavily optimized for real-world data patterns
- **Adaptive performance**: Timsort performs exceptionally well on already sorted or partially sorted data, explaining the massive speedups on ordered inputs (55,692% faster on sorted lists, 91,722% on reverse-sorted)

**Test Case Performance:**
- **Small lists (≤10 elements)**: Modest 8-36% improvements due to overhead being comparable
- **Large lists (1000 elements)**: Dramatic improvements of 10,000-90,000% faster, demonstrating the quadratic vs linearithmic complexity difference
- **Best for**: Large datasets, partially sorted data, and any production sorting needs where performance matters

The optimization maintains identical functionality, preserving in-place sorting behavior and all print statements.
