All comparison sort algorithms implicitly assume the transdichotomous model with K in Θ(log N), as if K is smaller we can sort in O(N) time using a hash table or integer sorting. If K ≫ log N but elements are unique within O (log N ) bits, the remaining bits will not be looked at by either quicksort or quick radix sort.

qsort is a C standard library function that implements a sorting algorithm for arrays of arbitrary objects according to a user-provided comparison function. It is named after the "quicker sort" algorithm [1] (a quicksort variant due to R. S. Scowen), which was originally used to implement it in the Unix C library, although the C standard does not require it to implement quicksort.

Multi-key quicksort, also known as three-way radix quicksort, [1] is an algorithm for sorting strings.This hybrid of quicksort and radix sort was originally suggested by P. Shackleton, as reported in one of C.A.R. Hoare's seminal papers on quicksort; [2]: 14 its modern incarnation was developed by Jon Bentley and Robert Sedgewick in the mid-1990s. [3]
While the Quick Sort article provides a comprehensive explanation of the algorithm, it could benefit from more real-world examples of how Quick Sort is used in different domains. For instance, the article could discuss how Quick Sort is used in data processing, image processing , or network analysis, and how it compares to other sorting ...
It is an example of a 2-regular sequence. [ 2 ] Asymptotically , the value of the n {\displaystyle n} th sorting number fluctuates between approximately n log 2 n − n {\displaystyle n\log _{2}n-n} and n log 2 n − 0.915 n , {\displaystyle n\log _{2}n-0.915n,} depending on the ratio between n {\displaystyle n} and the nearest power of ...
One example application of the double-ended priority queue is external sorting. In an external sort, there are more elements than can be held in the computer's memory. The elements to be sorted are initially on a disk and the sorted sequence is to be left on the disk. The external quick sort is implemented using the DEPQ as follows:
