FAQs

Question: What is the main advantage of Quick Sort over other sorting algorithms?
Answer: Quick Sort is generally faster than other sorting algorithms for large datasets due to its divide-and-conquer approach.

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