Strengths:

• The solutions are correct and handle edge cases appropriately.
• The code is well-commented and easy to understand.
• The time and space complexities are optimal for the given problems.

Areas for Improvement:

• For KdiffUniquePairs.java, consider using a single set to store pairs in a consistent order (e.g., always store the smaller number first) to avoid sorting within the loop. This could improve performance slightly.
• For PascalsTriangle.java, the base case for zero rows could be merged with the general case by initializing the triangle as empty and only adding rows if numRows > 0, simplifying the logic.
