• Strengths:

  • The student demonstrates a good understanding of the problems and provides multiple solutions where applicable.
  • The code is clean, well-commented, and follows best practices.
  • The student optimizes space and time complexity effectively, especially in the second solution for findDisappearedNumbers.

• Areas for Improvement:

  • For findDisappearedNumbers, the first solution could be noted as less space-efficient compared to the second solution. The student could consider always preferring the in-place modification approach when possible.
  • In gameOfLife, the dirs array could be declared as static final since it's a constant and doesn't change. This would be a minor optimization.

• Strengths:
  • The student demonstrates a strong understanding of time and space complexity optimizations.
  • The code is clean, well-commented, and easy to follow.
  • The use of in-place modifications and temporary states shows advanced problem-solving skills.
• Areas for Improvement:
  • For findDisappearedNumbers, the first approach with the hashmap is correct but could be noted that the second approach is more space-efficient.
  • In gameOfLife, the dirs array could be declared as a static final variable since it doesn't change, which is a minor optimization.
  • The comments could be slightly more detailed to explain why certain values (like 2 and 3) are used in the gameOfLife solution.
