Your solution for the "sort-colors.py" problem is excellent. It is efficient, with optimal time and space complexity, and the code is clear and concise. Well done! However, note that the problem you are solving is "Arrange Colors" (sort colors), but you included code for "3sum" and "container with most water" in the same response. This might be an error in your submission. In the future, ensure that you only provide the solution for the problem being evaluated. One minor point: in the condition for nums[mid] == 0, you increment mid after swapping. This is correct because after swapping, the element at mid is now 1 (since low was pointing to a 1 or 0, but after swapping with low, which is at a position that has been processed, it is safe to move mid). However, it's important to understand why we increment mid in this case but not when we swap with high. When swapping with high, we don't know what value we get from high, so we need to check it again in the next iteration. But when swapping with low, we know that low was pointing to a 1 (because low and mid have been traversing together until they meet a 2), so we can safely increment mid. Keep up the good work! |

The student's solution for Sort Colors is excellent. It correctly implements the required algorithm with optimal time and space complexity. The code is well-structured and easy to understand. However, note that the student included solutions for other problems (3Sum and Container With Most Water) in the same submission. While these are not directly relevant to the current problem, it's important to ensure that each solution is contained in its own file and that the code submitted for evaluation is specifically for the problem at hand. In this case, the Sort Colors solution is correct and complete. One minor suggestion: The condition Overall, the student has demonstrated a strong understanding of the problem and has provided an efficient solution. |
