When we have chosen a pivot and rearranged an array, the pivot is in its final position.

The best pivot is the median element of an array.

If we use the rightmost element as the pivot, the worst-case time complexity is O(n log n).

Partition is an operation that merges two subarrays separated by pivot.

After the algorithm has performed the partitioning, the subarrays on both sides of the pivot may be unsorted.
