No, the best-case running time of QuickSort is not always Ω(n log n). It is only guaranteed to have this time complexity in the best-case scenario where the pivot element is always the median of the array. In other cases, the time complexity can be worse, such as in the worst-ca...
Note that the total time taken to complete a quicksort algorithm depends on the input array and the deployed partition strategy. •Worst-Case: If the partition process always takes the smallest or largest element as the pivot, the worst case of a quick-sort algorithm is considered. ...
Space Complexity The average-case space complexity for the quick sort algorithm isO(Logn). It is the space required by the recursion stack. But in the worst-case when sorting an array requiresnrecursive, the space complexity isO(n).

Using asymptotic analysis, we can very well conclude the best case, average case, and worst case scenario of an algorithm.Asymptotic analysis is input bound i.e., if there's no input to the algorithm, it is concluded to work in a constant time. Other than the "input" all other factors...
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...
