• Strengths:
  • Correct implementation of the two-pointer technique across all problems.
  • Good handling of edge cases (e.g., skipping duplicates in "3 Sum").
  • Clear and concise code with appropriate comments.
• Areas for Improvement:
  • In "Sort Colors", the comment could explicitly mention the Dutch National Flag algorithm for better clarity.
  • The initial check if nums==None or len(nums)==0 in "Sort Colors" is redundant since the problem guarantees a non-empty array, but it doesn't hurt.
  • Consistency in variable naming (e.g., l and h vs. low and high) could be improved for better readability.

• The student has demonstrated a good understanding of the two-pointer technique and has applied it correctly in all three problems.
• The code is clean, well-commented, and follows best practices.
• The student has correctly identified and handled edge cases, such as skipping duplicates in the "3 Sum" problem and checking for null or empty arrays in "Sort Colors".
• One minor suggestion would be to add a brief comment explaining the Dutch National Flag algorithm in the "Sort Colors" solution for better clarity, though the code itself is self-explanatory.
