Complexity Analysis
- Time Complexity:
O(n) - Space Complexity:
O(1)
Performance Insight: The time complexity of this algorithm is linear (O(n)), scales linearly to TB-scale data and is suitable for streaming pipelines. Space overhead is minimal, making it suitable for memory-constrained or streaming environments.
Note: Complexity analysis is based on theoretical models. Actual runtime is affected by input scale, hardware, and implementation optimizations. Benchmark for your specific workload.
