• Pascal's Triangle: Excellent job! Your solution is correct, efficient, and well-commented. The time and space complexity analysis is accurate.
• K-diff Pairs: Good job providing multiple solutions with varying efficiencies. The first solution is correct but not optimal, so it's great that you included more efficient alternatives. For the third solution, consider adding a comment explaining why you handle k=0 separately, as it might not be immediately obvious to readers. Also, in the second solution, you have a bug in the duplicate skipping logic (you're checking nums[left] instead of sort[left]). Fixing this would make the solution fully correct.
