Merge sort. In all the cases the complexity is nlogn
For Quick sort complexity is o(n^2), nlogn in worst and best
cases respectively.

Answer / mr. x
Lots of ppl asked, nobody had a clue.
The best sorting algorithm on average depends on the data to
be sorted. If the data is more or less well evenly
distributed, the best sorting algorithm is Radixsort or
Bucketsort, with average and worst cases of O(n).
Next are a class of very complex algorithms (impractical)
which are O(n log log n).
Next are the O(n log n) algorithms. Mergesort and Heapsort
both show average and worst case complexities of O(n log n).
Quicksort is to be avoided as the plague!!!!! It has
non-deterministic complexity and has a worst-case behaviour
of O(n^2). No wonder why there are so many crappy
applications out there.
Then Shellsort is pretty good for small-to-medium lists, as
long as you choose the best gaps (around O(n log^2 n)).
Otherwise it can perform O(n^4/3) or even O(n^2)!.
All other sorts are to be avoided, except for very specific
cases or when simplicity is far more important than code
velocity.

Answer / bharath
on avg qsort is O(n) and worst is n^2;
msort is O(nlogn) for all
hsort is same as msort

Answer / shiva
obviously quick sort nly provide best avg behavior....

Answer / manoj ransing
The worst case behaviour or quick sort is n^2, but that of
heap sort is nlogn. The average case for both is nlogn.
