Strengths:

• The student has demonstrated a strong understanding of the two-pointer technique across different problems.
• The code is clean, well-commented, and follows best practices.
• The inclusion of test cases in the main method is excellent for verifying correctness.

Areas for Improvement:

• In MergeSortedArray.java, the comment "starting from end of an array because if we start from the beginning of array we will encounter second array goes unsorted" could be clearer. It might be better to explain that starting from the end avoids overwriting elements in nums1 that haven't been processed yet.
• In RemoveDuplicates.java, the comment "Space Complexity- O(n)" is incorrect; it should be O(1) since no additional space is used beyond the input array.
• In Search2DSortedMatrix.java, the comment "Time Complexity - O(m+n)" could be expanded to explain why this is the case (i.e., in the worst case, we traverse one row and one column).
