FAQs

Question: What is the main advantage of Quick Sort over other sorting algorithms?
Answer: Quick Sort is generally faster in practice due to its efficient partitioning process, making it suitable for large datasets.

Question: How does Merge Sort handle large data sets?
Answer: Merge Sort is effective for large datasets as it divides the data into smaller chunks, sorts them, and then merges them back together, ensuring stability.

Question: Are there any scenarios where Heap Sort is preferred?
Answer: Heap Sort is preferred when memory usage is a concern, as it sorts in place and has a guaranteed time complexity of O(n log n).
