Sorting Algorithm
This is a sorting algorithm.   It may be applied to a set of data in order to sort it.     For comparing various sorts, see compare sorts.   For other sorting algorithms,   see sorting algorithms,   or:

O(n logn) sorts

O(n log2n) sorts
Shell Sort

 Note:   jortSort is considered a work of satire.   It achieves its result in an intentionally roundabout way.   You are encouraged to write your solutions in the spirit of the original jortsort rather than trying to give the most concise or idiomatic solution.

JortSort is a sorting tool set that makes the user do the work and guarantees efficiency because you don't have to sort ever again.
It was originally presented by Jenn "Moneydollars" Schiffer at the prestigious   JSConf.

JortSort is a function that takes a single array of comparable objects as its argument.

It then sorts the array in ascending order and compares the sorted array to the originally provided array.

If the arrays match   (i.e. the original array was already sorted),   the function returns   true.

If the arrays do not match (i.e. the original array was not sorted), the function returns   false.

Translation of: Python
```F jortsort(sequence)
R Array(sequence) == sorted(sequence)

F print_for_seq(seq)
print(‘jortsort(#.) is #.’.format(seq, jortsort(seq)))

print_for_seq([1, 2, 4, 3])
print_for_seq([14, 6, 8])
print_for_seq([‘a’, ‘c’])
print_for_seq(‘CVGH’)
print_for_seq(‘PQRST’)```
Output:
```jortsort([1, 2, 4, 3]) is 0B
jortsort([14, 6, 8]) is 0B
jortsort([a, c]) is 1B
jortsort(CVGH) is 0B
jortsort(PQRST) is 1B
```

## Arturo

```jortSort?: function [a]->
a = sort a

test: function [a]->
print [a "is" (jortSort? a)? -> "sorted" -> "not sorted"]

test [1 2 3]
test [2 3 1]

print ""

test ["a" "b" "c"]
test ["c" "a" "b"]
```
Output:
```[1 2 3] is sorted
[2 3 1] is not sorted

[a b c] is sorted
[c a b] is not sorted```

## AutoHotkey

```JortSort(Array){
sorted:=[]
for index, val in Array
sorted[val]:=1
for key, val in sorted
if (key<>Array[A_Index])
return 0
return 1
}
```
Examples:
```Array1 := ["a", "d", "b" , "c"]
Array2 := ["a", "b", "c" , "d"]
MsgBox % JortSort(Array1) "`n" JortSort(Array2)
return
```
Outputs:
```0
1```

## BQN

BQN has a really simple way to represent JortSort:

```  JSort ← ≡⟜∧
JSort 3‿2‿1
0```

Which means "Does the array match itself sorted?"

Another equivalent function is `⊢≡∧`.

## C

Works with: GCC

This program tells if an array of integers numbers passed as input is sorted or not and gives the user some unpolite answers so, as asked by the specifications, "you don't have to sort ever again". As others did in this page, this example doesn't follow the request to sort the input array and then compare the sorted version to the original one to check if it was already sorted. It only checks if the input is sorted and behaves accordingly. I've tested this code only with gcc but should work with any C compiler.

```#include <stdio.h>
#include <stdlib.h>

int number_of_digits(int x){
int NumberOfDigits;
for(NumberOfDigits=0;x!=0;NumberOfDigits++){
x=x/10;
}
return NumberOfDigits;
}

int* convert_array(char array[], int NumberOfElements)  //converts integer arguments from char to int
{
int *convertedArray=malloc(NumberOfElements*sizeof(int));
int originalElement, convertedElement;

for(convertedElement=0, originalElement=0; convertedElement<NumberOfElements; convertedElement++)
{
convertedArray[convertedElement]=atoi(&array[originalElement]);
originalElement+=number_of_digits(convertedArray[convertedElement])+1; //computes where is the beginning of the next element

}
return convertedArray;
}

int isSorted(int array[], int numberOfElements){
int sorted=1;
for(int counter=0;counter<numberOfElements;counter++){
if(counter!=0 && array[counter-1]>array[counter]) sorted--;

}
return sorted;
}
int main(int argc, char* argv[])
{
int* convertedArray;

convertedArray=convert_array(*(argv+1), argc-1);

if(isSorted(convertedArray, argc-1)==1) printf("Did you forgot to turn on your brain?! This array is already sorted!\n");
else if(argc-1<=10) printf("Am I really supposed to sort this? Sort it by yourself!\n");
else printf("Am I really supposed to sort this? Bhahahaha!\n");
free(convertedArray);
return 0;

}
```

## J

Ironically, in J, implementing in the spirit of the original happens to also be the most concise and idiomatic way of expressing this algorithm:

Solution

```   jortsort=: -: /:~
```

More in line with the spirit of the task would be:

```   jortSort=: assert@(-: /:~)
```

Of course, ideally, assert would be replaced with something more assertive. Perhaps deleting all storage? But even better would be to send email to your boss and leadership explaining (at great length) exactly why they are all idiots. Do enough of this and you will never have to sort again...

Example Usage

```   jortsort 1 2 4 3
0
jortsort 'sux'
1
jortsort&> 1 2 4 3;14 6 8;1 3 8 19;'ac';'sux';'CVGH';'PQRST'
0 0 1 1 1 0 1
```

Using jortSort in place of jortsort would throw an error on all but the first of those examples. It would return an empty result for that first example. (We have no way of representing the consequences of the more inane proposals presented here.)

## Janet

```(defn jortsort [xs]
(deep= xs (sorted xs)))

(print (jortsort @[1 2 3 4 5])) # true
(print (jortsort @[2 1 3 4 5])) # false```

## Java

Optimized version of JortSort. Even less funny. Doesn't bother with sorting, but simply returns true. Very fast. Use only when you're absolutely sure that the input is already sorted. You may have to use an unoptimized version of JortSort to ascertain this.

```public class JortSort {
public static void main(String[] args) {
System.out.println(jortSort(new int[]{1, 2, 3}));
}

static boolean jortSort(int[] arr) {
return true;
}
}
```
`true`

## JavaScript

The original JavaScript implementation courtesy of the author, Jenn "Moneydollars" Schiffer.

```var jortSort = function( array ) {

// sort the array
var originalArray = array.slice(0);
array.sort( function(a,b){return a - b} );

// compare to see if it was originally sorted
for (var i = 0; i < originalArray.length; ++i) {
if (originalArray[i] !== array[i]) return false;
}

return true;
};
```

## jq

`def jortsort: . == sort;`

Example:

`[1, "snort", "sort", [1,2], {"1":2}] | jortsort`
Output:
```true
```

## Jsish

Based on the Javascript satire.

```/* jortSort in Jsish, based on the original satire, modified for jsish */
var jortSort = function(arr:array):boolean {
// make a copy
var originalArray = arr.slice(0);
// sort
arr.sort( function(a,b) { return a - b; } );
// compare to see if it was originally sorted
for (var i = 0; i < originalArray.length; ++i) {
if (originalArray[i] !== arr[i]) return false;
}
// yes, the data came in sorted
return true;
};

if (Interp.conf('unitTest')) {
;    jortSort([1,2,3]);
;    jortSort([3,2,1]);
;    jortSort([1, 'snort', 'sort', [1,2], {1:2}]);

* << is used to avoid numeric comparison
* 3 4e-1 is sorted

## PARI/GP

`jortSort(v)=vecsort(v)==v`

## Perl

```sub jortsort {
my @s=sort @_;  # Default standard string comparison
for (0..\$#s) {
return 0 unless \$_[\$_] eq \$s[\$_];
}
1;
}
```

The task wants us to sort, but we could implement this by just using cmp on the input array elements, which would be faster (especially with unsorted input).

## Phix

```type JortSort(sequence s)
return s=sort(s)
end type
```

Then any variable or constant delared as type JortSort raises an error if used incorrectly, eg

```JortSort ok = {1,2,3}
```
Output:

Note that while the above is fine under pwa/p2js and can be invoked explicitly, it does not automatically trigger the error.

```C:\Program Files (x86)\Phix\test.exw:2
type check failure, bad is {5,4,6}
```

Amusingly the compiler itself uses a variant of jortsort, in that pttree.e declares a whole bunch of ternary tree node constants for all the language keywords and builtins such as

```global constant T_while         = 336   tt_stringF("while",T_while)
```

and if you change that to 338 and try to recompile the compiler, you'll immediately get:

```while should be 336(not 338)
```

It does that because at the lowest level a cmp imm is at least twice as fast as a cmp [mem], and the only other way it could know these constants at compile-time would be to (re)build a 5000-node ternary tree, though I will concede that any sane person would have written a program to write an include file rather than hacking these things by hand.
There is a similar thing in pwa\src\p2js_keywords.e, though it automatically checks, prompts, and auto-rebuilds that for you.

## Quackery

`jortsortwith` returns `true` if the nest is sorted, sort order is specified after `jortsortwith`, so `jortsortwith >` returns `true` if a nest of numbers is sorted in ascending numerical order, and `jortsortwith \$<` returns `true` if a nest of strings is sorted in descending lexicographical order.

```  [ dup
' [ sortwith ]
]'[ nested join
do = ]                          is jortsortwith ( [ --> b )```

### The Non-satirical version

Jortsort, as specified in this task, is a sensible function ("is this nest sorted?) done inefficiently. This is the efficient version, with a more sensible name.

``` [ true swap
]'[ temp put
dup [] != if
[ tuck temp share do if
[ dip not conclude ] ] ]
drop
temp release ]                   is sortedwith ( [ --> b )```

## Racket

```#lang racket/base
(define (jort-sort l [<? <])
(equal? l (sort l <?)))
```

Racket's sort function is efficient in that it starts by checking the input, so the above could be made more efficient with a pointer equality test:

```#lang racket/base
(define (jort-sort l [<? <])
(eq? l (sort l <?)))
```

And an explicit implementation that checks the order (note that Racket's sort expects a “smaller-than” comparator):

```#lang racket/base
(define (jort-sort l [<? <])
(or (null? l)
(for/and ([x (in-list l)] [y (in-list (cdr l))])
(not (&lt;? y x))))) ; same as (&lt;= x y) but using only &lt;?
```

## Raku

(formerly Perl 6)

```sub jort-sort { @_ eqv @_.sort }
```

Actually, there's a better internal sort that seems to work best for lists that are already completely sorted, but tends to fails for any other list. The name of this sort, [!after], is completely opaque, so we're pretty much forced to hide it inside a subroutine to prevent widespread panic.

```sub jort-sort-more-better-sorta { [!after] @_ }
```

However, since Perl 6 has a really good inliner, there's really little point anyway in using the [!after] reduction operator directly, and jort-sort-more-better-sorta is really much more self-documenting, so please don't use the reduction operator if you can. For example:

Output:
```\$ perl6
> [!after] <a b c>  # DON'T do it this way
True
> [!after] 1,3,2    # DON'T do it this way either
False```

## REXX

REXX has no built-in sort, so an   exchange sort   is included here.

The array elements (items) may be any form of number that REXX supports, and/or they can be alphabetic characters.

### using sort

```/*REXX program  verifies  that  an array  is sorted  using  a   jortSort   algorithm.   */
parse arg \$                                      /*obtain the list of numbers from C.L. */
if \$=''  then \$=1 2 4 3                          /*Not specified?  Then use the default.*/
say 'array items='  space(\$)                     /*display the list to the terminal.    */
if jortSort(\$)  then say  'The array is sorted.'
else say  "The array isn't sorted."
exit                                             /*stick a fork in it,  we're all done. */
/*──────────────────────────────────────────────────────────────────────────────────────*/
eSort:    procedure expose @.;                    h=@.0       /*exchange sort.*/
do while h>1;                 h=h%2
do i=1  for @.0-h;          j=i;      k=h+i
do  while @.k<@.j;        t=@.j;    @.j=@.k;    @.k=t
if h>=j  then leave;      j=j-h;    k=k-h
end   /*while @.k<@.j*/
end     /*i*/
end       /*while h>1*/
return
/*──────────────────────────────────────────────────────────────────────────────────────*/
jortSort: parse arg x;   @.0=words(x)                         /*assign # items in list. */
do j=1  for @.0; !.j=word(x,j); @.j=!.j /*save a copy of original.*/
end   /*j*/
call eSort                                          /*sort with exchange sort.*/
do k=1  for @.0
if !.k\==@.k  then return 0             /*the array isn't sorted. */
end   /*k*/
return 1                                            /*the array is    sorted. */
```

output   when using the default input:   1   2   4  3

```array items= 1 2 4 3
The array is not sorted.
```

output   when using the input:     0   -0   +0   0.0e-9   1   01   001   +1   1.0   1e8

```array items= 0 -0 +0 0.0e-9 1 01 001 +1 1.0 1e8
The array is sorted.
```

output   when using the input:   cat dog eye fox gnu hog pig wombat something

```array items= cat dog eye fox gnu hog pig wombat something
The array is not sorted.
```

### using comparisons

In the   http://jort.technology/   webpage, the   jortSort   is defined as:
jortSort checks if your inputs are sorted.

Nothing is mentioned how it does this, and it certainly doesn't say that it sorts the input to verify if it's in order.

```/*REXX program  verifies  that  an array  is sorted  using  a   jortSort   algorithm.   */
parse arg \$                                      /*obtain the list of numbers from C.L. */
if \$=''  then \$=1 2 4 3                          /*Not specified?  Then use the default.*/
say 'array items='  space(\$)                     /*display the list to the terminal.    */
if jortSort(\$)  then say  'The array is sorted.'
else say  "The array isn't sorted."
exit                                             /*stick a fork in it,  we're all done. */
/*──────────────────────────────────────────────────────────────────────────────────────*/
jortSort: parse arg x
p=word(x,1)
do j=2  to words(x);  _=word(x,j)
if _<p  then return 0                      /*array  isn't sorted.*/
p=_
end   /*j*/
return 1                                                /*array  is    sorted.*/
```

output   is the same as the 1st REXX version.

## Ring

```aList = [4,2,3,1]
see jortSort(aList) + nl

func jortSort array
originalArray = array
array = sort(array)
for i= 1 to len(originalArray)
if originalArray[i] != array[i] return false ok
next
return true```

## Ruby

```def jort_sort(array)
array == array.sort
end
```
Translation of: JavaScript
```def jort_sort(array)
# sort the array
original_array = array.dup
array.sort!

# compare to see if it was originally sorted
original_array.length.times do |i|
return false if original_array[i] != array[i]
end

true
end
```

## Rust

Translation of: JavaScript
```use std::cmp::{Ord, Eq};

fn jort_sort<T: Ord + Eq + Clone>(array: Vec<T>) -> bool {
// sort the array
let mut sorted_array = array.to_vec();
sorted_array.sort();

// compare to see if it was originally sorted
for i in 0..array.len() {
if array[i] != sorted_array[i] {
return false;
}
}

return true;
}
```

Using iterators:

```fn jort_sort<T>(slice: &[T]) -> bool
where
T: Ord + PartialEq + Clone,
{
let mut sorted = slice.to_vec();
sorted.sort_unstable();

slice
.iter()
.zip(sorted.iter())
.all(|(orig, sorted)| orig == sorted)
}
```

Idiomatic:

```fn jort_sort<T>(slice: &[T]) -> bool
where
T: Ord + PartialEq + Clone,
{
let mut sorted = slice.to_vec();
sorted.sort_unstable();

slice == sorted
}
```

## Scala

As of Scala 2.13, the .deep method has been removed from Array. The Java deepEquals() method will work as a replacement.

```import java.util.Objects.deepEquals

def jortSort[K:Ordering]( a:Array[K] ) = deepEquals(a.sorted, a)
```

## Sidef

```func jort_sort(array) { array == array.sort };
```

## SSEM

This program expects to find a zero-terminated array of positive integers in sequential storage addresses beginning at address 27. If the array is correctly sorted into ascending order, the machine will halt with all accumulator bits clear; if not, it will halt with all accumulator bits set.

Like one or two of the other solutions, the SSEM implementation does not first sort the array and then test the sorted version for equality with the original (something that would probably require more storage space than we have at our disposal): it simply reads through the array in order, checking that each element is not less than the previous one. This difference should be considered an implementation detail.

There are a couple of limitations that make the program less useful than it would otherwise be. Firstly, it is essentially a single-shot application: if you want to test a second array, you will need to manually reset storage address 0 to 16411 and storage address 26 to 0. Secondly, the SSEM's modest storage capacity means that the largest array you can sort (or not sort) using this program consists of (the terminating zero, and) four integers. Subject to those provisos, however, the program should be found to meet the specification satisfactorily.

## Swift

```func jortSort<T:Comparable>(array: [T]) -> Bool {
return array == sorted(array)
}
```
Translation of: JavaScript
```func jortSort<T:Comparable>(inout array: [T]) -> Bool {

// sort the array
let originalArray = array
array.sort({\$0 < \$1})

// compare to see if it was originally sorted
for var i = 0; i < originalArray.count; ++i {

## Tcl

set list [list {*}\$list]    ;# ensure canonical list form
set options [lrange \$args 0 end-1]

}
```

This supports all of the options known to the native lsort command, making it quite natural to use. The commented line ensures it will do the right thing for any list, even if it has funny formatting because it's embedded in source:

```% jortsort -decreasing -integer {  222 33  1 }

## XPL0

Translation of: Wren
```include xpllib; \for Sort

func JortSort(A, N);
int  A, N, B, I;
def  SizeOfInt = 4;
[B:= Reserve(N*SizeOfInt);
for I:= 0 to N-1 do B(I):= A(I);
Sort(B, N);
for I:= 0 to N-1 do
if B(I) # A(I) then return false;
return true;
];

int Tests, Test, I;
def Size = 5;
[Tests:= [ [1, 2, 3, 4, 5], [2, 1, 3, 4, 5] ];
for Test:= 0 to 2-1 do
[ChOut(0, ^[);
for I:= 0 to Size-2 do
[IntOut(0, Tests(Test,I));  Text(0, ", ")];
IntOut(0, Tests(Test,I));
Text(0, "] -> ");
Text(0, if JortSort(Tests(Test), Size) then "sorted" else "not sorted");
CrLf(0);
];
]```
Output:
```[1, 2, 3, 4, 5] -> sorted
[2, 1, 3, 4, 5] -> not sorted
```

## zkl

Two "solutions", a linear one and one that actually sorts.

`fcn jort(list){ False!=list.reduce(fcn(a,b){ (a>b) and return(Void.Stop,False); b }) }`
`fcn jort(list){ list==list.copy().sort() }`
Output:
```zkl: jort(T(1,2,4,3))
False
zkl: jort(T(14,6,8))
False
zkl: jort(T("a","c"))
True
zkl: jort(T("s","u","x"))
True
zkl: jort("CVGH")
False
zkl: jort("PQRST")
True
zkl: var a=List(11,2,3); jort(a)
False
zkl: a
L(11,2,3)
zkl: jort(List)
True
zkl: jort(List(1))
True
```
