   4 days ago · QuickSort is a sorting algorithm based on the Divide and Conquer algorithm that picks an element as a pivot and partitions the given array around the picked pivot by placing the pivot in its correct position in the sorted array. How does QuickSort work? The key process in quickSort is a partition () .

   Picking a good pivot is necessary for the fast implementation of quicksort. However, it is typical to determine a good pivot. Some of the ways of choosing a pivot are as follows - 1. Pivot can be random, i.e. select the random pivot from the given array. 2. Pivot can either be the rightmost element of the leftmost element of the given array. 3. Sel...

   Now, let's see the working of the Quicksort Algorithm. To understand the working of quick sort, let's take an unsorted array. It will make the concept more clear and understandable. Let the elements of array are - In the given array, we consider the leftmost element as pivot. So, in this case, a[left] = 24, a[right] = 27 and a[pivot] = 24. Since, p...

   What is the difference between sorting and quicksort?

   • So, it is important to discuss the topic. Sorting is a way of arranging items in a systematic manner. Quicksort is the widely used sorting algorithm that makes n log n comparisons in average case for sorting an array of n elements. It is a faster and highly efficient sorting algorithm. This algorithm follows the divide and conquer approach.

   What is the space complexity of quicksort algorithm?

   • Space Complexity The space complexity for quicksort is O(log n). Quicksort algorithm is used when Quicksort is an algorithm based on divide and conquer approach in which an array is split into sub-arrays and these sub arrays are recursively sorted to get a sorted array.

   How to use sorted array in quicksort?

   • Pick median as pivot. The key process in quickSort is partition (). Target of partitions is, given an array and an element x of array as pivot, put x at its correct position in sorted array and put all smaller elements (smaller than x) before x, and put all greater elements (greater than x) after x.
