- Optimize performance if needed

### 4. Final Review

4. Performance Benchmarking

Measuring and comparing your solutions.

Benchmarking Framework

# Python example for timing solutions
import time
import random

def benchmark_solution(solution_func, test_data, iterations=1000):
    """Benchmark a solution function."""
    times = []

    for _ in range(iterations):
        start_time = time.perf_counter()
        result = solution_func(test_data.copy())  # Use copy to avoid mutation
        end_time = time.perf_counter()
        times.append(end_time - start_time)

    avg_time = sum(times) / len(times)
    min_time = min(times)
    max_time = max(times)

    return {
        'average': avg_time,
        'min': min_time,
        'max': max_time,
        'result': result
    }

# Usage example
def bubble_sort(arr):
    # Bubble sort implementation
    pass

def quick_sort(arr):
    # Quick sort implementation
    pass

# Test data
test_data = [random.randint(0, 1000) for _ in range(1000)]

# Benchmark both solutions
bubble_results = benchmark_solution(bubble_sort, test_data)
quick_results = benchmark_solution(quick_sort, test_data)

print(f"Bubble Sort: {bubble_results['average']:.6f}s (avg)")
print(f"Quick Sort: {quick_results['average']:.6f}s (avg)")
