-- empty list is already sorted
qsort [] = []
-- choose first element as pivot,
-- put all elements less than x on the left,
-- put all elements greater than x on the right,
-- recurse on both sides
qsort (x:xs) = qsort (filter (< x) xs) ++ [x] ++ qsort (filter (>= x) xs)

Yes, that's how quick-sort works.
18 A list is ordered from smaller to largest when a sort is called Which sort would take the longest time to execute?
Quick Sort
Which sort show the best average behaviour?
quick sort
When is quick sort better than selection sort?
Because the quick sort can be used for large lists but selection not. selection sort is used to find the minimum element ,but quick choose element called pivot and move all smaller nums before it & larger after it.

When quick sort is preferred?
When you want to sort an array.
Why quick sort is called quick?
Although quick sort has a worst case time complexity of O(n^2), but for sorting a large amount of numbers, quick sort is very efficient because of the concept of locality of reference.
