(** {6 Sorting} *)
val sort : ('a -> 'a -> int) -> 'a array -> unit
(** Sort an array in increasing order according to a comparison
function. The comparison function must return 0 if its arguments
compare as equal, a positive integer if the first is greater,
and a negative integer if the first is smaller (see below for a
complete specification). For example, {!Pervasives.compare} is
a suitable comparison function, provided there are no floating-point
NaN values in the data. After calling [Array.sort], the
array is sorted in place in increasing order.
[Array.sort] is guaranteed to run in constant heap space
and (at most) logarithmic stack space.
The current implementation uses Heap Sort. It runs in constant
stack space.
Specification of the comparison function:
Let [a] be the array and [cmp] the comparison function. The following
must be true for all x, y, z in a :
- [cmp x y] > 0 if and only if [cmp y x] < 0
- if [cmp x y] >= 0 and [cmp y z] >= 0 then [cmp x z] >= 0
When [Array.sort] returns, [a] contains the same elements as before,
reordered in such a way that for all i and j valid indices of [a] :
- [cmp a.(i) a.(j)] >= 0 if and only if i >= j
*)
val stable_sort : ('a -> 'a -> int) -> 'a array -> unit
(** Same as {!Array.sort}, but the sorting algorithm is stable (i.e.
elements that compare equal are kept in their original order) and
not guaranteed to run in constant heap space.
The current implementation uses Merge Sort. It uses [n/2]
words of heap space, where [n] is the length of the array.
It is usually faster than the current implementation of {!Array.sort}.
*)
val fast_sort : ('a -> 'a -> int) -> 'a array -> unit
(** Same as {!Array.sort} or {!Array.stable_sort}, whichever is faster
on typical input.
