FAQs

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

Question: How does Merge Sort handle large datasets?
Answer: Merge Sort divides the dataset into smaller parts, sorts them, and then merges them back together, which is efficient for large inputs.
