Strengths:

• The student correctly identified the inefficiency in the initial approach and provided an optimized solution.
• The code is well-commented and easy to understand.
• The student demonstrated a good understanding of the problem and the data structures involved.

Areas for Improvement:

• The initial solution using a single stack is inefficient and could be omitted in favor of the optimized version.
• The comments could be more detailed in explaining why the optimized approach works (e.g., the amortized time complexity).
• The student could consider adding edge case handling (e.g., handling null or invalid inputs) to make the solution more robust.
