Which sorting algorithm have same worst-case and average case?
Sorting algorithms
| Algorithm | Data structure | Space complexity:Worst |
|---|---|---|
| Quick sort | Array | O(n) |
| Merge sort | Array | O(n) |
| Heap sort | Array | O(1) |
| Smooth sort | Array | O(1) |
What are the worst-case and average case complexity?
The time complexity of Quick Sort in the best case is O(nlogn). In the worst case, the time complexity is O(n^2). Quicksort is considered to be the fastest of the sorting algorithms due to its performance of O(nlogn) in best and average cases.
Which algorithm has lowest best and average case complexity?
Which of the following sorting algorithms has the lowest worst-case complexity? Merge sort. Bubble sort.
Which sorting algorithm has the lowest best case complexity?
Merge sorting
Merge sorting has the minimum worst case complexity..
Which is the best and worst case sorting technique?
Best and average time complexity: n+k where k is the number of buckets. Worst case time complexity: n^2 if all elements belong to same bucket. A sorting technique is inplace if it does not use any extra memory to sort the array.

What is the best and worst case time complexity?
Best case time complexity: n when array is already sorted. Worst case: when the array is reverse sorted. Best, average and worst case time complexity: n^2 which is independent of distribution of data. Best, average and worst case time complexity: nlogn which is independent of distribution of data.
Do you do average or worst case analysis of algorithms?
Knowing the worst-case performance of an algorithm provides a guarantee that the algorithm will never take any time longer. Sometimes we do the average case analysis on algorithms. Most of the time the average case is roughly as bad as the worst case.
