• The main issue is that your solution does not address the problem that was given (implementing a HashSet). Please ensure you carefully read and understand the problem statement before starting to code.
• For the 2D matrix search problem you solved, your implementation is correct and efficient. The use of binary search is appropriate, and your variable naming and comments are clear.
• In the future, double-check that you're working on the correct problem and that your solution matches the requirements.
