  • Strengths: The student has correctly implemented a dynamic programming solution that is both efficient and easy to understand. The use of comments and clear variable names enhances readability.
  • Areas for Improvement: The space complexity could be optimized further by using only three variables instead of a full DP table. This would reduce the space complexity from O(n) to O(1). Additionally, the edge case for an empty input is handled correctly, but the comment could be more descriptive to explain why returning 0 is appropriate in this case.
