Votre objectif est d'écrire un programme qui imprime le poème suivant exactement tel qu'il apparaît ici:

There was an old lady who swallowed a fly.
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old lady who swallowed a spider,
That wriggled and iggled and jiggled inside her.
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old lady who swallowed a bird,
How absurd to swallow a bird.
She swallowed the bird to catch the spider,
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old lady who swallowed a cat,
Imagine that to swallow a cat.
She swallowed the cat to catch the bird,
She swallowed the bird to catch the spider,
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old lady who swallowed a dog,
What a hog to swallow a dog.
She swallowed the dog to catch the cat,
She swallowed the cat to catch the bird,
She swallowed the bird to catch the spider,
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old lady who swallowed a horse,
She died of course.

Le texte doit apparaître exactement comme ici, et le moins de caractères gagne.

Perl 5.10, 392 384 372 235 369 (ASCII) / 234 (Unicode)

La version ASCII la plus courte contient 369 caractères:

Perhaps she'll die.

$_";$_.="$c$P.
$t";s/&/ to! a$c/}s/!/ swallow/g;s/J/iggled /g;say"$_ horse,
She died of course."

Cela a commencé à partir de ce programme de base:

my @animals = qw(fly spider bird cat dog);
my $buf = "There was an old lady who swallowed a ";
for my $phrase ( "",
                 ",\nThat wriggled and iggled and jiggled inside her",
                 ",\nHow absurd&",
                 ",\nImagine that&",
                 ",\nWhat a hog&" ) { 
  $previous = $current;
  $current = shift @animals;
  $trail = $previous ? "She swallowed the $current to catch the $previous,\n$trail"
                     : "I don't know why she swallowed that $current,\n"
                       . "Perhaps she'll die.\n\n$buf";
  $buf .= "$current$phrase.\n$trail";
  $buf =~ s/&/ to swallow a $current/;
}
say "$buf horse,\nShe died of course.";

L'idée centrale est de garder la fin de la rime et le début de la suivante $trail, en l'augmentant au fur et à mesure. Il est rendu non trivial par la nécessité d'un cas spécial pour la première utilisation et la tentative de réutiliser la variable du nom de l'animal même dans la phrase spécifique à l'animal. D'autres optimisations incluent:

• identificateurs à un caractère pour tout
• utiliser des mots nus au lieu de chaînes entre guillemets pour la liste des animaux
• utilisation de l'accumulateur $_pour $bufraccourcir encore plus la plupart des opérations de substitution (l'utilisation de @_est par force d'habitude et ne gagne rien de plus que n'importe quel autre personnage)
• y compris l'espace précédent directement à l'intérieur de la variable du nom de l'animal (le caractère d'espace tiré de la $"variable)
• substitution regexp pour raccourcir les phrases les plus courantes: ' swallow'et'iggled '
• aucun espacement de code que ce soit et tous \nles littéraux de chaîne remplacés par des sauts de ligne réels

Tout sauf la dernière optimisation donne ceci:

@_ = (fly, spider, bird, cat, dog);
$_ = "There was an old lady who!ed a";
for $P ( "",
         ",\nThat wrJand Jand jJinside her",
         ",\nHow absurd&",
         ",\nImagine that&",
         ",\nWhat a hog&" ) { 
  $p = $c;
  $c = $" . shift @_;
  $t = $p ? "She!ed the$c to catch the$p,\n$t"
          : "I don't know why she!ed that$c,\nPerhaps she'll die.\n\n$_";
  $_ .= "$c$P.\n$t";
  s/&/ to! a$c/;
}
s/!/ swallow/g;
s/J/iggled /g;
say "$_ horse,\nShe died of course.";

De plus, ce golf est victime du problème d'encodage sous-spécifié. Comme il compte - à partir de maintenant - des caractères individuels au lieu d'octets dans un codage spécifié, il y a un gros gain à réaliser en décodant la source du programme à partir de UCS2 avant de commencer. Le résultat final n'est plus très lisible, mais il est très court. (234 caractères, comptés comme une différence par rapport perl -E''à d'habitude) (j'ai dû inclure le retour à la ligne pour le rendre valide UCS2)

Une bonne chose, il y avait beaucoup de golf avant de recourir à Unicode, ou ce ne serait pas très amusant.

Explication

LIST B=fly,spider,bird,cat,dog,horse           // Ink's "LIST"s aren't much like lists - they're more like enums. Here we create a list type stating what animals exist, and make a set containing none of them.
VAR s=" swallow "                              // Pretty self-explanatory
-(i)~B=B(i)                                    // The i label keeps track of how many times we've visited it. We set B (the set) to be equal to the i-th item in B (the list type).
There was an old lady who{s}ed a {B}{.|,}      // Print the first line. {.|,} is a sequence - it's a period the first time it's encountered, and a comma every subsequent time.
                                               // Sequences can have more than one item in them, which is how we print the second line. When we get to the horse one, we terminate the program right away.
{|That wriggled and iggled and jiggled inside her|How absurd|Imagine that|What a hog|She died of course.->END}{|.|to{s} a {B}}.}
-(k)~B--                                       // Step back through the list type.
{B:                                            // A conditional - we execure the next two lines if B is non-empty.
She{s}ed the {B+1} to catch the {B},           // Print the "she swallowed the..." line
->k                                            // And repeat
}I don't know why she{s}ed that fly,           // Only reached when the conditional fails.
Perhaps she'll die.
\                                              // A backslash and a space to force an empty line.

Cette solution est un décompresseur de 46 octets BinaryDeserialize@ByteArray@ToCharacterCode@"..."agissant sur un tableau de 248 octets se faisant passer pour une chaîne ASCII. Le transfert de cette chaîne entre différents programmes est un peu délicat. TIO, par exemple, fait exploser cette solution dans 416 octets en utilisant le codage UTF-8 au lieu de conserver la chaîne ASCII. Pour obtenir la solution minimale de 295 octets, enregistrez le texte dans une variable textet exécutez

BinaryWrite["ThereWasAnOldLady.wl", Join[
  ToCharacterCode["BinaryDeserialize@ByteArray@ToCharacterCode@\""],
  Normal[BinarySerialize[text, PerformanceGoal -> "Size"]] /. {34 -> Sequence[92, 34]},
