;Task:
Sort an array (or list) of integers in ascending numerical order.
Use a sorting facility provided by the language/library if possible.

You could also use the built-in sorted() function:

AppleScript has no native sort function.
Later versions of AppleScript (OS X 10.10 onwards) do allow access to the ObjC NSArray library,
but while this approach can yield reasonably fast sorts, it is slow in terms of scripter time,
requiring digestion of the ObjC library documentation, and leading to code like the '''sort''' function
below, which is possibly more messy than it is worth for the purposes of casual end-user scripting,
for which AppleScript was presumably designed.
<syntaxhighlight lang="applescript">use framework "Foundation"

=={{header|Babel}}==
Use the sortval operator to sort an array of integers (val-array in Babel terminology). The following code creates a list of random values, converts it to a val-array, sorts that val-array, then converts it back to a list for display using the lsnum utility.
<syntaxhighlight lang="babel">babel> nil { zap {1 randlf 100 rem} 20 times collect ! } nest dup lsnum ! --> Create a list of random numbers
( 20 47 69 71 18 10 92 9 56 68 71 92 45 92 12 7 59 55 54 24 )
babel> ls2lf --> Convert list to array for sorting
babel> dup {fnord} merge_sort --> The internal sort operator
babel> ar2ls lsnum ! --> Display the results
( 7 9 10 12 18 20 24 45 47 54 55 56 59 68 69 71 71 92 92 92 )</syntaxhighlight>
In Babel, lists and arrays are distinct. If you want to sort a list, use the lssort utility:
<syntaxhighlight lang="babel">babel> ( 68 73 63 83 54 67 46 53 88 86 49 75 89 83 28 9 34 21 20 90 )
babel> {lt?} lssort ! lsnum !
( 9 20 21 28 34 46 49 53 54 63 67 68 73 75 83 83 86 88 89 90 )</syntaxhighlight>
To reverse the sort-order, use the 'gt?' predicate instead of the 'lt?' predicate:
<syntaxhighlight lang="babel">babel> ( 68 73 63 83 54 67 46 53 88 86 49 75 89 83 28 9 34 21 20 90 ) {gt?} lssort ! lsnum !
( 90 89 88 86 83 83 75 73 68 67 63 54 53 49 46 34 28 21 20 9 )</syntaxhighlight>

=={{header|Bracmat}}==
As a Computer Algebra system, Bracmat transforms expressions to a canonical form.
Terms in a sum are sorted and, where possible, added together.
So the task is partially solved by expressing the list as a sum of terms.
Evaluating the list sorts the list, but also adds like terms.
To illustrate, this is what happens when entering our list at the prompt:
<pre>{?} (9.)+(-2.)+(1.)+(2.)+(8.)+(0.)+(1.)+(2.)
{!} (-2.)+(0.)+2*(1.)+2*(2.)+(8.)+(9.)</pre>
The use of a computationally inert operator like the dot <code>.</code> is essential:
<pre>{?} (9)+(-2)+(1)+(2)+(8)+(0)+(1)+(2)
{!} 21</pre>
To complete the task need to unfold the terms with a numerical factor >1:
<syntaxhighlight lang="bracmat">{sort takes a list of space-separated integers}
(sort=
sum elem sorted n
. 0:?sum
& whl
' (!arg:%?elem ?arg&(!elem.)+!sum:?sum)
& :?sorted
& whl
' ( !sum:?n*(?elem.)+?sum
& whl
' ( !n+-1:~<0:?n
& !sorted !elem:?sorted
)
)
& !sorted);
out$sort$(9 -2 1 2 8 0 1 2);</syntaxhighlight>
{{out}}
<pre>-2 0 1 1 2 2 8 9</pre>
This solution becomes very ineffective for long lists. To add a single term to an already sorted sum of N terms requires on average N/2 steps. It is much more efficient to merge two already sorted sums of about equal length.
Also, adding elements to the end of the list 'sorted' is costly. Better is to prepend elements to a list, which will have inverted sorting order, and to invert this list in an extra loop.

Icon and Unicon lists allow mixed type and the built-in function 'sort' will deal with mixed type arrays by sorting by type first then value. Integers sort before, reals, strings, lists, tables, etc. As a result a list of mixed numeric valuess (i.e. integers and reals) will not sort by numeric value, rather the reals will appear after the integers. Sort returns a sorted copy of it's argument. It will also perform some type conversion, such converting an unordered set into an ordered list.
In the example below, L will remain an unsorted list and S will be sorted.
<syntaxhighlight lang="icon">S := sort(L:= [63, 92, 51, 92, 39, 15, 43, 89, 36, 69]) # will sort a list</syntaxhighlight>

The verb<tt> /:~ </tt>sorts <i>anything</i> that J can represent. For example:

/:~ a
15 36 39 43 51 63 69 89 92 92</
Arrays of any rank are treated as lists of component arrays. Thus <tt>/:~</tt> sorts not only atoms within a list, but whole lists within a table, tables within a three-axis array, and so on. The level of structure at which sorting occurs may also be specified, so that <tt>/:~"1</tt> sorts the atoms within the finest-grained list within the array, regardless of the overall rank of the array.

Pop11 library function sorts lists. So we first convert array to list, then sort and finally convert back:

Line 444 ⟶ 2,086:

The above can be abbreviated to more economical, but possibly more opaque, syntax, using pop11 as a functional language:

consvector(destlist(sort(conslist(destvector(ar))))) -> ar;
;;; print the sorted vector:
ar =>
** {1 2 2 3 4}</
(The list created by conslist will be garbage-collected.)
Line 458 ⟶ 2,100:
Alternatively, using the datalist function, even more economically:

===Array===
Scala's "default" Array is a ''mutable'' data structure, very close to Java's Array. Generally speaking, that means an "array" is not very Scala-lesque, even as mutable data structures go. It can serves a purpose, though. If array is the right data type for your need, then that is how you sort it.<syntaxhighlight lang="scala">import scala.compat.Platform
object Sort_an_integer_array extends App {
val array = Array((for (i <- 0 to 10) yield scala.util.Random.nextInt()):
_* /*Sequence is passed as multiple parameters to Array(xs : T*)*/)
/** Function test the array if it is in order */
def isSorted[T](arr: Array[T]) = array.sliding(2).forall(pair => pair(0) <= pair(1))
assert(!isSorted(array), "Not random")
scala.util.Sorting.quickSort(array)
assert(isSorted(array), "Not sorted")
println(s"Array in sorted order.\nSuccessfully completed without errors. [total ${Platform.currentTime - executionStart} ms]")

===List===

{{libheader|Scheme/SRFIs}}
Sorting is also available through SRFIs. SRFI 132 provides separate list-sort and vector-sort routines:
<syntaxhighlight lang="scheme">
> (import (srfi 132))
> (list-sort < '(9 -2 1 2 8 0 1 2))
(-2 0 1 1 2 2 8 9)
> (vector-sort < #(9 -2 1 2 8 0 1 2))
#(-2 0 1 1 2 2 8 9)
</syntaxhighlight>
SRFI 132 replaced the older SRFI 95, which is still found in many implementations. SRFI 95 provides a generic sort function (but note the order of the sequence and comparator!):
<syntaxhighlight lang="scheme">
> (import (srfi 95))
> (sort '(9 -2 1 2 8 0 1 2) <)
(-2 0 1 1 2 2 8 9)

Each shell parameter separates the integers using the default IFS whitespace (space, tab, newline).
<syntaxhighlight lang="bash">nums="2 4 3 1 5"
sorted=`printf "%s\n" $nums | sort -n`
Alternate solution: <tt>sorted=`for i in $nums; do echo $i; done | sort -n`</tt>
----
Some shells have real arrays. You still need IFS to split the string from <tt>sort -n</tt> to an array.
