What are some optimizations for the quicksort algorithm?

Some common optimizations for quicksort include using median-of-three for pivot selection, switching to insertion sort for small subarrays, and using tail recursion.

Can you explain the median-of-three pivot selection?

Sure! The median-of-three method selects the pivot as the median of the first, middle, and last elements of the array, which helps to avoid worst-case scenarios.

What is the benefit of switching to insertion sort for small subarrays?

Switching to insertion sort for small subarrays can improve performance because insertion sort is faster for small datasets due to lower overhead.

Are there any other advanced techniques for quicksort?

Yes, techniques like randomizing the pivot and using a hybrid approach with other sorting algorithms can further enhance quicksort's efficiency.
