• Strengths:
  • The solutions are correct and handle edge cases appropriately.
  • The code is clean, well-commented, and easy to understand.
  • The student has correctly analyzed and stated the time and space complexities.
• Areas for Improvement:
  • For problem1, consider using a hashing technique (like the reference solution) to avoid sorting and achieve a better time complexity.
  • While the solutions are efficient, always look for potential optimizations to further improve performance, especially for large inputs.

• Strengths:
  • The student demonstrates a strong understanding of hash maps and their applications in solving these problems.
  • The code is clean, well-commented, and follows good practices.
  • The student correctly identifies and handles edge cases, such as in Problem3 where the pattern length must match the number of words.
• Areas for Improvement:
  • For Problem1, consider using a hashing approach with prime numbers to avoid sorting, which would improve the time complexity from O(n * k log k) to O(n * k).
  • While the current solutions are correct, exploring alternative approaches (like the one in the reference solution) can help in understanding different optimization techniques.
