• Strengths: The student has a good understanding of the two-pointer technique and has implemented it correctly. The approach of merging from the end to avoid overwriting is well-executed. The comments and variable naming are clear and helpful.
• Areas for Improvement: While the solution is correct, the student could consider adding a brief comment explaining why the remaining elements in nums1 (if any) don't need to be moved, as they are already in place. This would make the solution even more understandable for someone reviewing the code.

• The student's solution for problem2.java is excellent. It correctly implements the merging of two sorted arrays from the end, which is an optimal approach. The code is clean, efficient, and well-commented.
• The student has demonstrated a good understanding of the problem and has provided a solution that is both correct and efficient. The approach of starting from the end to avoid overwriting is a key insight that the student has correctly identified and implemented.
• The comments and variable names are clear, making the code easy to understand. The student has also correctly identified the time and space complexity, which shows a good grasp of algorithmic analysis.
