Array sorting choosing tech

#1

when to use which array sorting technique in array?

#2

almost all the times we prefer using either mergesort or quicksort, as there time complexity is O(nlogn). But in the cases where you have some prior knowledge of input, you can use other sorting algorithms as well like,

  1. if the input is almost sorted and small in size, you can use bubble sort.
  2. for very small size input, insertion and selection sort are preferred.

Thanks
