It has an average O(n log n) complexity and it’s one of the most used sorting algorithms, especially for big data volumes. The name "Quick Sort" comes from the fact that a quick sort can sort a list of data elements significantly faster (twice or thrice faster) than any of the common sorting algorithms. It works by dividing the input array into two sub-arrays, then recursively sorting each sub-array independently, and finally combining the sorted sub-arrays. In Quick sort algorithm, partitioning of the list is performed using following steps. Quick sort has a space complexity of O(logn), making it a suitable algorithm when you have restrictions in space availability. QuickSort is a Divide and Conquer algorithm, which picks an element as "pivot" and partitions a given list around the pivot.
