WebFor quick sort, we could imagine a worse than average case where we get unlucky and: - for odd levels we choose the worst possible pivot i.e. all elements are to the left or right of the pivot. - for even levels we choose a pivots where 3/4 of the elements are on one side and 1/4 on the other side.

WebHeapsort has a worst- and average-case running time of \(O(n \log n)\) like mergesort, but heapsort uses \(O(1)\) auxiliary space (since it is an in-place sort) while mergesort takes up \(O(n)\) auxiliary space, so if memory concerns are an issue, heapsort might be a good, fast choice for a sorting algorithm.

WebAverage case takes 0.26N less comparisons than worst case. Therefore, in Average Case: Average Case Time Complexity: O(N logN) Number of Comparisons: 0.74 N logN; Worst Case Time Complexity of Merge Sort. One thing one can note is that for sorting we compare the elements and try to use these comparisons to give us an orderly sequence. WebThe worst-case of your implementation is Θ(n^2) and the best-case is O(nlogn) which is reasonable for shell-sort. The best case ∊ O(nlogn): The best-case is when the array is already sorted. The would mean that the inner if statement will never be true, making the inner while loop a constant time operation.
