• Strengths:
  • The student has correctly implemented the optimal solution with the correct time and space complexity.
  • The code is clean, well-commented, and easy to understand.
  • The approach of merging from the end is well-explained and correctly implemented.
• Areas for Improvement:
  • While the solution is correct, it would be beneficial to handle edge cases explicitly (e.g., when nums2 is empty or when nums1 has no initial elements). Although the current implementation handles these cases implicitly, explicit checks could make the code more robust and easier to debug.
  • The student could consider adding a brief explanation of why merging from the end is advantageous (to avoid overwriting elements in nums1 that haven't been processed yet).
