What is the best case time complexity of Quick Sort?
Understand the Problem
The question is asking for the best case time complexity of the Quick Sort algorithm, which is a concept commonly studied in computer science and algorithm analysis. The user is required to identify the correct option from the provided choices based on their knowledge of the algorithm.
Answer
O(n log n)
The final answer is O(n log n)
Answer for screen readers
The final answer is O(n log n)
More Information
The best-case time complexity of Quick Sort occurs when the partitions are as evenly balanced as possible, resulting in O(n log n) complexity. This optimal division minimizes the number of comparisons needed during sorting.
Tips
A common mistake is confusing the best-case with average-case time complexity, which is also O(n log n) but occurs under different circumstances.
