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: How does Merge Sort differ from Quick Sort?
Answer: Merge Sort divides the array into halves and sorts them independently, while Quick Sort selects a pivot and partitions the array around it.
