WebSep 7, 2024 · Its type in Haskell looks like this: sort :: Ord a => [a] -> [a] By sorting a list, we gained a knowledge that now all elements in the list are in the increasing (or decreasing) order. But the type of a sorted list is the same as the type of any other list. So there is no way to know in advance, whether a list is sorted or not. http://learn.hfm.io/recursion.html
