Strengths:

  • The student has implemented a highly efficient solution with O(n) time complexity, which is a significant improvement over the reference solution.
  • The code is clean, well-organized, and easy to understand.
  • The use of a two-pass approach (left and right passes) is a clever optimization that avoids the need for nested loops.

Areas for Improvement:

  • While the solution is already optimal, adding a brief comment explaining the two-pass approach could make the code even more understandable for someone reading it for the first time.
  • The variable name rp (running product) could be expanded to something more descriptive like runningProduct to enhance readability, though this is a minor point.
