Malbolge Unshackled (variante de rotación de 20 trits), 3,62e6 bytes
El tamaño de esta respuesta excede el tamaño máximo de programa postable (eh), por lo que el código se encuentra en mi repositorio de GitHub (nota: no copie el código usando CTRL + A y CTRL + C, solo haga clic derecho y haga clic en "Guardar elemento de destino como. .. ").
¿Cómo ejecutar esto?
Esto podría ser una parte difícil, porque el ingenuo intérprete de Haskell tardará siglos en ejecutarlo. TIO tiene un intérprete decente Malbogle Unshackled, pero lamentablemente no podré usarlo (limitaciones).
La mejor que pude encontrar es la variante de ancho de rotación fija de 20 trits, que funciona muy bien, calculando (más o menos) al instante .
Para que el intérprete sea un poco más rápido, eliminé todas las comprobaciones del intérprete Malbolge Unshackled de Matthias Lutter.
