Ваша цель - написать программу, которая печатает следующее стихотворение в точности так, как оно выглядит здесь:

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.

Самая короткая версия ASCII длиной 369 символов:

@_=(fly,spider,bird,cat,dog);$_="There was an old lady who!ed a";for$P("",",
That wrJand Jand jJinside her",",

Perhaps she'll die.

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

Это началось с этой базовой программы:

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.";

Основная идея состоит в том, чтобы сохранить конец рифмы и начало следующего $trail, увеличивая его по мере продвижения вперед. Это стало нетривиальным из-за необходимости особого случая для первого использования и попытки повторно использовать переменную имени животного даже в фразе, специфичной для животного. Дальнейшие оптимизации включают в себя:

• односимвольные идентификаторы для всего
• использование голых слов вместо строк в кавычках для списка животных
• использование аккумулятора $_для $bufсокращения большинства операций замещения еще больше (использование @_по привычке и не выигрывает ничего больше, чем любой другой символ)
• включая предшествующий пробел непосредственно внутри переменной имени животного (символ пробела, взятый из $"переменной)
• регулярное_выражение замены сократить наиболее распространенные фразы: ' swallow'и'iggled '
• никакой пробел в коде и все \nв строковых литералах заменены реальными символами новой строки

Все, кроме последней оптимизации, дают следующее:

@_ = (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.";

Кроме того, этот гольф является жертвой недостаточно определенной кодировки. Поскольку на данный момент он подсчитывает отдельные символы вместо байтов в указанной кодировке, можно добиться большого выигрыша за счет декодирования исходного кода программы из UCS2 перед запуском. Окончательный результат уже не очень читабелен, но он короткий. (234 символа, считаются отличием от perl -E''обычного) (мне пришлось включить завершающий перевод строки, чтобы сделать его действительным UCS2)

Хорошо, что до того, как прибегнуть к Unicode, нужно было много играть в гольф, иначе было бы не очень весело.

Редактировать: не могу найти способ скопировать / вставить 234-символьную версию в этот браузер, поэтому я оставляю 235-символьную версию. Это будет исправлено сегодня вечером, когда я возьму в руки настоящий буфер обмена с поддержкой UTF8. нашел способ. Квазиустойчиво на идеоне.

объяснение

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

Perhaps she'll die.

Это решение - 46-байтовый декомпрессор, BinaryDeserialize@ByteArray@ToCharacterCode@"..."действующий на 248-байтовом массиве, маскирующемся как строка ASCII. Перенос этой строки между различными программами немного сложен. TIO, например, расширяет это решение до 416 байт, используя кодировку UTF-8 вместо сохранения строки ASCII. Чтобы получить минимальное 295-байтовое решение, сохраните текст в переменной textи запустите

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

затем выполните сгенерированный файл в командной строке с
