Overview of Quicksort
Explore the quicksort algorithm, focusing on its divide-and-conquer method and in-place sorting. Understand the partitioning process, pivot selection, and recursive sorting of subarrays to achieve efficient average-case performance.

Like merge sort, quicksort uses divide-and-conquer, and so it's a recursive algorithm. The way that quicksort uses divide-and-conquer is a little different from how merge sort does. In merge sort, the divide step does hardly anything, and all the real work happens in the combine step. Quicksort is the opposite: all the real work happens ...
