• The student's solution for "Merge Sorted Array" is excellent. It correctly implements the two-pointer technique starting from the end of the arrays, which is the optimal approach for this problem.
• The comments and variable names are clear, making the code easy to understand.
• The solution handles all edge cases, including when nums2 has remaining elements after the initial merge loop.
• The time and space complexity are optimal, matching the reference solution.

For the other problems ("Search a 2D Matrix II" and "Remove Duplicates from Sorted Array II"), the student has provided multiple approaches, which is good practice. However, the focus here is on the "Merge Sorted Array" problem, where the student's solution is correct and efficient.
