• Strengths:

  • Both solutions are correct and handle edge cases well.
  • The use of backtracking is implemented cleanly and effectively.
  • Comments are present and helpful, though could be more detailed.

• Areas for Improvement:

  • Time and space complexity analysis needs to be more accurate. For problem1.java, the time complexity is O(2^m) and space complexity is O(n^2). For problem2.java, the space complexity is O(n).
  • Avoid claiming O(1) space complexity when it's not accurate. Recursion inherently uses stack space.
  • Consider adding more detailed comments, especially for complex logic like in problem2.java.
