FAQs

Question: What is the time complexity of Quick Sort?
Answer: The average time complexity of Quick Sort is O(n log n), while the worst-case complexity is O(n²).

Question: When should I use Merge Sort instead of Quick Sort?
Answer: Merge Sort is preferred when stability is required or when dealing with large datasets that do not fit into memory.
