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.

The algorithm takes little more average time than standard merge sort algorithms, free to exploit O(n) temporary extra memory cells, by less than a factor of two. Though the algorithm is much faster in a …

An example of a QuickSort algorithm coded in VBScript.

We've partnered with Dartmouth college professors Tom Cormen and Devin Balkcom to teach introductory computer science algorithms, including searching, sorting, recursion, and graph theory.

Median of medians can also be used as a pivot strategy in quicksort, yielding an optimal algorithm, with worst-case complexity . [citation needed] The median of medians algorithm guarantees a worst-case …

In this post, I'll explain what an algorithm really is, cover the main different types/categories with simple examples, and share some of the best visual videos (with animations) that helped me understand …

The Fastest Sorting Algorithm Timsort is one of those foundational sorting algorithms used everywhere, but most explanations of how it works shy away from going into its behavior in depth. We are going …

Each is an example of a divide and conquer algorithm which recursively breaks the problem to be solved down into smaller chunks. How quick is Quicksort? As we said in the previous article , the number of …
