What are some common array optimization algorithms?

Common array optimization algorithms include QuickSort, MergeSort, and Binary Search. Would you like to know more about any specific one?

Can you explain how QuickSort works?

QuickSort is a divide-and-conquer algorithm that selects a 'pivot' element and partitions the array into two sub-arrays. Elements less than the pivot go to one side, and those greater go to the other. This process is recursively applied to the sub-arrays.

What is the time complexity of QuickSort?

The average time complexity of QuickSort is O(n log n), but in the worst case, it can degrade to O(n²) if the pivot is poorly chosen.

Are there any optimizations for QuickSort?

Yes, some optimizations include choosing a better pivot (like the median), using insertion sort for small sub-arrays, and implementing tail recursion.
