Quick Sort Program In C Without Using Function
C program for Quick Sort. C program for Quick Sort. Quick Sort also known as Partition exchange sort, is a comparison unstable in place sorting algorithm. Quick Sort compare n items in Onlogn time complexity in average and best case, while takes On. It comes under divide and conquer algorithm which divides the large set of array in small by picking up a pivot element as a reference element, and do sorting. You can also see other sorting algorithm implementation like, Heap sort, bubble sort, Insertion sort, selection sort etc. Quick Sort Algorithm Steps 1. Make a list of items that need to be sorted, lets apply in an array. Choose any element as pivot element from the array list. Complexity largely depends on choosing the pivot element3. Rearrange the array list so that all the elements with value less than the pivot will come before the pivot and the element with value greater will come after the pivot with in the same array, which make pivot element in the sorted position. If the reverse the order we are reversing the sorting order that is descending. Virtuemart File Upload'>Virtuemart File Upload. Apply recursively the 3rd step to the sub array of the element with smaller values and separate the sub array of the elementswith the greater values. Note In the below implemented quick sort program, always first element is set as Pivot element. But if array is already sorted, then the time complexity becomes worse, as quick sort will take quadratic time. So pivot element should be chosen in such a way, that partitioning of array becomes half. C program for Quick Sortincludelt stdio. Index, int last. Index. Index, temp, index. Index lt last. Index.
