Which sorting algorithm has best complexity?
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) |
Is there a known sorting algorithm that runs faster than big on log n?
Quicksort is a well-known sorting algorithm that, on average, makes O(n log n) comparisons to sort n items.
Can you sort faster than n log n?
Yes, but only by cheating. There are two ways to cheat; both depend on restrict the types of your input data. You can insist that you will only sort data that is already known to be partially sorted in some way. Best-case complexity for some standard sorting algorithms is already O(n).
Which method is best for sorting?
Quicksort
Quicksort. Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well. The first thing to do is to select a pivot number, this number will separate the data, on its left are the numbers smaller than it and the greater numbers on the right.
Which sorting algorithm is the fastest?
If you’ve observed, the time complexity of Quicksort is O(n logn) in the best and average case scenarios and O(n^2) in the worst case. But since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.
Which is best asymptotic runtime complexity sorting?
Answer: Insertion Sort and Heap Sort has the best asymptotic runtime complexity. Explanation: It is because their best case run time complexity is – O(n).
Which sorting is best for large data?
Quicksort is probably more effective for datasets that fit in memory. For larger data sets it proves to be inefficient so algorithms like merge sort are preferred in that case. Quick Sort in is an in-place sort (i.e. it doesn’t require any extra storage) so it is appropriate to use it for arrays.
What is the fastest sorting algorithm?
But since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.
Is there a log n sort?
This means that any sorting algorithm has a lower bound of n , and since n > log(n) , a log(n) sort is impossible.

What is the complexity of heap sort?
The heapsort algorithm itself has O(n log n) time complexity using either version of heapify.
