Strengths:

• The solution correctly implements the Dutch National Flag algorithm, which is the optimal approach for this problem.
• The code is well-commented, making it easy to understand the logic.
• The use of a helper function for swapping is good practice, as it improves code readability and reusability.
• The solution handles edge cases (like when the array is empty or has only one element) implicitly, as the algorithm naturally handles these.

Areas for Improvement:

• While the solution is correct, the student included solutions for two other problems (Problem2.java and Problem3.java) that were not requested. In the future, the student should ensure they only submit the solution for the problem being evaluated.
• The comment at the top mentions "Problem1.java", but the class name is "Solution". This is acceptable, but it's important to note that the file name should match the class name in Java if the class is public. However, since this is likely for a coding platform, it is not a critical issue.

Overall, the solution for the "Arrange Colors" problem is excellent and meets all requirements.
