Strengths:
- The solution correctly implements the optimal approach using a dictionary to achieve O(n) time complexity.
- The code is clean, readable, and follows best practices.
- The logic for checking complements and storing indices is correctly implemented.
Areas for Improvement:
- The variable name sum might be slightly misleading since it actually represents the complement (target - current element). Consider renaming it to complement for clarity.
- The method returns default when no solution is found, which is not explicitly handled in the problem constraints (since the problem states there is exactly one solution). However, it would be good practice to handle edge cases explicitly, perhaps by throwing an exception or returning a meaningful default value if the problem constraints were not guaranteed.
