• Strengths:
  • The student has a good understanding of the two-pointer technique and has applied it effectively across different problems.
  • The code is clean, well-commented, and easy to follow.
  • The student has correctly handled edge cases, such as skipping duplicates in the 3Sum problem.
• Areas for Improvement:
  • For the Sort Colors problem, the student could mention why the current pointer is incremented only when nums[current] is 0 or 1, but not when it's 2. A brief comment explaining this would enhance understanding.
  • In the 3Sum problem, the student could add a check to break early if nums[i] > 0, since the array is sorted and no triplet can sum to zero beyond that point.
  • The student could consider adding more test cases in comments to demonstrate edge cases, such as all elements being the same in Sort Colors or empty input in Container With Most Water.
