1. Correctness: The solution is almost correct but fails due to a bug in the swap method where nums[j] = nums[i] should be nums[j] = temp. This causes incorrect swapping of elements.
2. Time Complexity: The time complexity is correctly O(n), matching the reference solution.
3. Space Complexity: The space complexity is correctly O(1), matching the reference solution.
4. Code Quality: The code is well-structured and readable. The use of meaningful variable names and comments is good.
5. Efficiency: The solution is efficient, but the bug in the swap method needs to be fixed to ensure correct functionality.

To improve, the student should:

• Fix the swap method to correctly swap elements.
• Consider adding more comments to explain the logic, especially for the two-pointer approach.
• Test the solution with edge cases (e.g., empty array, array with all 0s, all 1s, or all 2s) to ensure robustness.
