- Review code with fresh eyes
- Apply code review checklist
- Identify areas for improvement
### 3. Refactoring
- Address identified issues
- Improve structure and readability
- Optimize performance if needed
### 4. Final Review
- Ensure all requirements are met
- Verify edge case handling
- Check for regressions
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)")
