Scowen), which was originally used to implement it in the unix c library, although the c standard does. Efficient sorting is important for optimizing the efficiency of other algorithms (such as search and merge algorithms) that require input data to be in sorted lists. Quicksort was developed by british computer scientist tony hoare in 1959 [1] and published in 1961

[2] it is still a commonly used algorithm for sorting
Overall, it is slightly faster than merge sort and heapsort for randomized data, particularly on larger distributions
Introsort is performed first (introsort itself being a hybrid of quicksort and heap sort), to a maximum depth given by 2×log 2 n, where n is the number of elements, followed by an insertion sort on the result. It begins with quicksort, it switches to heapsort when the recursion depth exceeds a level based on (the logarithm of) the number of elements being sorted and it switches to insertion. In computer science, quickselect is a selection algorithm to find the k th smallest element in an unordered list, also known as the k th order statistic Like the related quicksort sorting algorithm, it was developed by tony hoare, and thus is also known as hoare's selection algorithm
Merge sort in computer science, a sorting algorithm is an algorithm that puts elements of a list into an order The most frequently used orders are numerical order and lexicographical order, and either ascending or descending
