FAQs

Question: What is the main advantage of using Merge Sort over Quick Sort?
Answer: Merge Sort is more efficient for larger datasets and is stable, making it suitable for applications where stability is crucial.

Question: How does Heap Sort differ from other sorting algorithms?
Answer: Heap Sort uses a binary heap data structure to sort elements, which allows it to achieve a time complexity of O(n log n) without requiring additional space.
