Best, worst and average case

Quicksort's average time complexity is O(n log n)

Quicksort is a popular sorting algorithm known for its efficiency. On average, it performs n log n comparisons to sort n elements. This average performance is often used as a benchmark for comparing other sorting algorithms.

Example

If you have an array of 1000 elements, quicksort will, on average, require approximately 1000 * log2(1000) ≈ 10,000 comparisons to sort the array.

Remember this

Understanding quicksort's average time complexity helps in choosing the right sorting algorithm for a given problem, ensuring efficient data processing.
