Dada la entrada de un "hotel" en el arte ASCII con una habitación individual marcada, envíe el número de la habitación de acuerdo con ciertas reglas.

Aquí hay un ejemplo de un hotel ASCII:

               ##
               ##
#####          ##
#####  ######  ##
#####  ######  ##
#####  ######  ##

Aquí hay algunas cosas más sobre los hoteles ASCII:

• Cada "edificio" está representado por un rectángulo de #caracteres, donde cada uno #representa una "habitación".

• El hotel anterior consta de tres edificios. Cada edificio está separado por dos columnas de espacios, y el "piso" más bajo siempre estará en la última línea.

• Cada edificio siempre tendrá entre 1 y 9 "pisos" (filas) y entre 1 y 9 "habitaciones" en cada piso. También siempre habrá 1-9 edificios.

• Las habitaciones están numeradas de la siguiente manera: [building #][floor #][room on floor #]. Por ejemplo, marquemos algunas habitaciones en el dibujo anterior:

                 ##
                 ##
  #####          ##
  #####  ####$#  ##
  ##%##  ######  ##
  #####  ######  #@
  

  La habitación marcada con la %es la habitación 123 (edificio 1, planta 2, tercera habitación en el piso). De manera similar, la habitación marcada con la $es la habitación 235 y la @habitación 312.

• Los edificios, los pisos y la "enésima habitación en el piso" siempre están indexados en 1.

La entrada consistirá en un hotel ASCII con una habitación individual reemplazada por un asterisco ( *). Esta es la habitación para la que debe generar el número de habitación. La entrada debe tomarse como una sola cadena, pero puede usar comas como separadores de línea en lugar de nuevas líneas (en caso de que su idioma de elección no pueda tomar una entrada de varias líneas o si es más corto para tomar una entrada de una sola línea). Opcionalmente, puede requerir una coma / nueva línea final. También puede rellenar líneas con espacios finales para hacer que la entrada sea un rectángulo completo.

Como se trata de código de golf , gana el código más corto en bytes.

Demostración

Esto usa un truco de golf que nunca he usado antes: Asignar a una variable ( K) dentro de una función ( y) para guardar un resultado parcial de esa función.

Explicación:

LxKh/#\*b\*jkhM[//<hJ_.zyJd2xJKycK
L                                     Define y(b):      (b is a list of strigs)
    /#\*b                             Filter b for strings containing '*'
   h                                  Take the first such string
  K                                   Store it in K
 x       \*                           And return the index of '*' in that string.
                      .z              Take the input as a list of strings
                     _                Reverse it (bottom to top)
                    J                 Store in J
                   h                  Take the bottommost row
                        yJ            Find y(J). This is the index in whichever
                                      row of J has the * of the *. Also store
                                      that row in K.
                  <                   Slice J up to that index.
                 /        d           Count the number of spaces
                /          2          Divide by 2. This is the building number.
                            xJK       Take the index in J of K. This is the floor.
                                cK    Chop K on whitespace.
                               y      Find the index in whatever element of K has
                                      the * of the *. This is the room number.
                                      This also overwrites K, but we don't care.
               [                      Gather the above into a list.
             hM                       Convert 0-indexing to 1-indexing.

awk, 70

!i{i=index($0,"*")}i{$0=substr($0,0,i);f++}END{print NF f length($NF)}

Ejemplo:

Input:
#
#  #
#  #  ##
#  #  ##  ###
#  #  ##  ###  #####
#  #  ##  ###  ##*##  ########
#  #  ##  ###  #####  ########

While no * was found, do nothing.
#
#  #
#  #  ##
#  #  ##  ###
#  #  ##  ###  #####
A * is found in column 14. From now on, truncate and increment the floor counter.
#  #  ##  ###  ##*    f=1
#  #  ##  ###  ###    f=2
Awk automatically splits $0 into space separated fields, counted by builtin NR.
In the end, NR and f hold hotel and floor number.
The room number is the length of the last hotel.

Python 2.7, 153 168 caracteres

¡Me gustó este desafío! Si una lista de Python está bien como entrada (ver ejemplos de prueba), esta solución funciona.

Editar 2016-01-05: se agregó una línea (10 caracteres) para dividir la cadena en varias líneas.

Breve explicación:

• t es la fila en la que se encuentra la habitación (contada desde la fila superior como índice de matriz = 0);
• i es el índice de la habitación en su fila;
• el edificio se calcula como el número de espacios en blanco dobles en la fila inferior hasta i;
• piso es el número de fila menos t;
• habitación es el índice del primer espacio en blanco doble en la cadena invertida desde iel comienzo del piso con la habitación, agregada por un espacio en blanco para cubrir el caso de que la habitación esté en el primer edificio.

Código:

def r(l):
 l=h.split(",")
 a,w,s="*","  ",str
 t=l.index(filter(lambda c:a in c,l)[0])
 i=l[t].find(a)
 return s(l[-1][:i].count(w)+1)+s(len(l)-t)+s((l[t][i::-1]+w).find(w))

Robé la idea de fusión de valores de ecatmur, pero los fusioné de una manera bastante diferente ( al final, ahorra 8 bytes ). Esto también supone lo mismo EOF == -1.

La entrada se toma de stdin, y no debe tener espacios en blanco o nuevas líneas después del último edificio en la última línea, por lo que una entrada de ejemplo sería:

printf "##\n##       #\n##  ##*  #\n##  ###  #" | ./hotel
# or for better visualisation:
printf "##\n##       #\n##  ##*  #\n##  ###  #" | tee /dev/fd/2 | ./hotel;echo ""

Descompostura:

// Globals initialise to 0
f,     // floor number * 10 + shift
b,     // building number * 100 + room number
x,     // current column
p=110; // will store column of * (must start >= 11*9-2, and 110 will be used later)
main(c){
    while(~(c=getchar()))              // For each character until EOF
        c<11                           //  Is \n? (10)
            ?f+=c,                     //   Add 10 to floor number
