Why bubble sort best case time complexity is O N?
Time Complexity of Bubble sort Best case scenario: The best case scenario occurs when the array is already sorted. Hence, time complexity in the best case scenario is O(n) because it has to traverse through all the elements once.
Which sorting algorithm has O N complexity in best case?
Sorting algorithms
| Algorithm | Data structure | Time complexity:Best |
|---|---|---|
| Heap sort | Array | O(n log(n)) |
| Smooth sort | Array | O(n) |
| Bubble sort | Array | O(n) |
| Insertion sort | Array | O(n) |

Program we have seen earlier and thereby compute the Big O notation of this program. So let’s
How bubble sort best case is N?
The best case for bubble sort occurs when the list is already sorted or nearly sorted. In the case where the list is already sorted, bubble sort will terminate after the first iteration, since no swaps were made. In this worst case, it take n iterations of n/2 swaps so the order is, again, n2.
Why do bubble sort algorithm is preferred over other techniques of sorting?
When the elements of input are already sorted, the bubble sort gives the best time complexity O(n). Bubble sort is typically slower due to it’s iterative behaviour.
Which algorithm has best time complexity such as O N?
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 sorting algorithm has time complexity of O N?
Time Complexities of all Sorting Algorithms
| Algorithm | Time Complexity | |
|---|---|---|
| Best | Worst | |
| Insertion Sort | Ω(n) | O(n^2) |
| Heap Sort | Ω(n log(n)) | O(n log(n)) |
| Quick Sort | Ω(n log(n)) | O(n^2) |
What is the big O time complexity analysis of bubble sort?
Bubble Sort is an easy-to-implement, stable sorting algorithm with a time complexity of O(n²) in the average and worst cases – and O(n) in the best case.
What is the time complexity of bubble sort Mcq?
Explanation: The best case time complexity of recursive bubble sort is O(n). It occurs in the case when the input is already/almost sorted.
