• The student's solution is well-implemented and matches the reference solution in terms of correctness, time complexity, and space complexity.
• The comments and variable names are clear, making the code easy to understand.
• One minor improvement could be to add a comment explaining why the second while loop (for remaining elements in nums2) is necessary, as it might not be immediately obvious to all readers.
• Overall, the solution is excellent and demonstrates a good understanding of the problem and the two-pointer technique.

• The solution is correct and efficient, matching the reference solution in both time and space complexity.
• The comments and variable naming are clear, making the code easy to understand.
• One minor improvement could be to add a comment explaining why the second while loop (for remaining elements in nums2) is necessary, as it might not be immediately obvious to all readers.
• The code could also benefit from a brief explanation of the edge cases handled (e.g., when one array is empty).
