Complexity Analysis

  • Time Complexity: O(n * d)
  • Space Complexity: O(n)

Performance Insight: The time complexity of this algorithm is polynomial. Linear space can often be reduced by constant factors via sliding-window techniques.

Note: Complexity analysis is based on theoretical models. Actual runtime is affected by input scale, hardware, and implementation optimizations. Benchmark for your specific workload.
