Welcome to the Bubble Sort in Mathematica page! Here, you’ll find the source code for this program as well as a description of how the program works.

```
(* Code *)
(* The actual bubble sort operating on Mathematica lists: *)
(* keep making passes over the list until it stops changing *)
bubbleSort = Function[{l},
FixedPoint[Function[{l},
(* pass over a pair of elements in the list *)
Fold[Function[{l, i},
(* element pair is out of order?*)
If[l[[i]] > l[[i + 1]],
(* swap the two elements *)
Permute[l, Cycles[{{i, i + 1}}]],
l]],
l, (* begin with the list in its original state *)
Range[Length[l] - 1]]],(* over each pair of elements *)
l]];
(* The outer function provides the 'user interface': *)
bubbleSortMain = l \[Function]
Module[{e =
"Usage: please provide a list of at least two integers to sort in the format \"1, 2, 3, 4, 5\""},
Catch[
StringRiffle[
bubbleSort@
(* list must have more than one element *)
If[Length[#] > 1, #, Throw[e]] & @
Map[
(* convert string to integer, or throw *)
s \[Function] If[StringMatchQ[s, DigitCharacter ..],
FromDigits[s],
Throw[e]],
(* construct arguments to bubble sort: list of items *)
StringSplit[l, ", "],
{-1} (* at each leaf *)],
", "]]];
(* Valid Tests *)
Print /@ bubbleSortMain /@ {
"4, 5, 3, 1, 2",
"4, 5, 3, 1, 4, 2",
"1, 2, 3, 4, 5",
"9, 8, 7, 6, 5, 4, 3, 2, 1"
};
(* Invalid Tests *)
