• The student's solution is well-implemented and follows the correct approach for the problem. The use of three pointers and the swapping logic is correctly applied.
• The code is clean and easy to understand, with good variable naming and a clear structure.
• One minor improvement could be to add comments explaining the purpose of each pointer and the overall algorithm, especially for someone who might be new to the Dutch National Flag problem.
• The helper function swap is a good practice, but it could be made private if it's only used within the class, to adhere to encapsulation principles.

• The student's solution is well-implemented and follows the correct approach for the problem.
• The use of comments to explain the logic is commendable and helps in understanding the code.
• The helper function swap is a good practice and improves code readability.
• The solution handles edge cases well, such as skipping duplicates in the 3Sum problem and correctly managing the pointers in the sortColors problem.
• One minor suggestion would be to ensure consistent formatting (e.g., spacing around operators and braces) to enhance readability further.
