Strengths:

• The student has correctly implemented the solutions for both problems.
• The code is well-commented and easy to understand.
• The student has used helper methods effectively to break down the problem.

Areas for Improvement:

• For Problem-1, consider using a more efficient approach to count pairs without storing them as strings. For example, you could use a HashMap to count frequencies and then check for pairs.
• The solution for Problem-2 could be simplified by removing the special cases for numRows == 1 and numRows == 2, as the general case already handles these scenarios.
• Ensure that the problem descriptions and reference solutions are correctly matched in future submissions to avoid confusion.
