Quick sort is empirically fastest among all the O(nlogn) sorting algorithms. Time Complexity: Best, Average, T(n) = 2T(n/2) + O(n) => O(nlogn) Worst case (e.g. a sorted array) T(n) = T(n-1) + O(n) =>O(n^2) Space Complexity(From wiki). Quicksort with in-place an...
Therefore, the time complexity of the Quicksort algorithm in worst case is Alternatively, we can create a recurrence relation for computing it. In the worst case, after the first partition, one array will have element and the other one will have elements. Let’s say denotes the time comple...
QuickSort is known for its efficiency, with an average-case time complexity of . It's widely used in practice due to its good performance and simplicity. Let's delve deeper into the partitioning process with an example using the given image. Example of QuickSort Partitioning Consider the array...

However, the quicksort algorithm has better performance for scattered pivots. Best Case Complexity [Big-omega]:O(n*log n) It occurs when the pivot element is always the middle element or near to the middle element. Average Case Complexity [Big-theta]:O(n*log n) ...

Quick Sort Algorithm also has some weaknesses that you should be aware of: Worst-case scenario: Quick Sort Algorithm has a worst-case time complexity of O(n²). This occurs when the pivot point is poorly chosen, resulting in a large number of comparisons and swaps. ...
Quicksort is an elegant sorting algorithm that is very useful in most cases. It’s generally an “in-place” algorithm, with the average time complexity ofO(n log n). Another interesting point to mention is that Java’sArrays.sort()method uses Quicksort for sorting arrays of primitives. Th...
