Hard Difficulty
Hard questions require advanced understanding and critical thinking. Here, your problem-solving skills are key, as these questions often involve complex scenarios needing in-depth analysis and well-structured responses.
Algorithms question
Algorithm questions test your understanding of computational procedures and efficiency. Be prepared to discuss time/space complexity, optimization techniques, and demonstrate your ability to convert abstract problems into working code.
Here's a Hint
Consider both iterative and recursive approaches, and be prepared to discuss time and space complexity of your solution.
