The conversation between human and AI assistant.
Which sorting algorithm is best if it is already sorted & why?
Ah, that makes sense. And what about if the data is completely unsorted?
For completely unsorted data, the best algorithms would be Quick Sort or Merge Sort. They both have average time complexities of O(N log N), which is very efficient. Quick Sort has a shorter average running time, but Merge Sort is more stable and can be used for various types of data.
