• Strengths:

  • The use of double hashing is a good approach and correctly implemented.
  • The code is well-structured and readable, with clear helper methods.
  • The comments are helpful and explain the approach well.

• Areas for Improvement:

  • The remove method should actually remove the entry rather than setting it to null to avoid potential issues with subsequent operations.
  • Consider handling the case where the key is 0 separately, similar to the reference solution, to ensure correctness.
  • The space efficiency could be improved by using a more compact data structure, like the boolean array in the reference solution.
