Dada a entrada de um "hotel" na arte ASCII com um quarto individual marcado, imprima o número do quarto de acordo com certas regras.

Aqui está um exemplo de um hotel ASCII:

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

Aqui estão mais algumas coisas sobre os hotéis ASCII:

• Cada "edifício" é representado por um retângulo de #caracteres, onde cada #um representa uma "sala".

• O hotel acima consiste em três edifícios. Cada edifício é separado por duas colunas de espaços, e o "piso" mais baixo estará sempre na última linha.

• Cada edifício sempre terá de 1 a 9 "andares" (linhas) e 1 a 9 "quartos" em cada andar. Também sempre haverá 1-9 edifícios.

• Os quartos são numeradas da seguinte forma: [building #][floor #][room on floor #]. Por exemplo, vamos marcar algumas salas no desenho acima:

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

  A sala marcada com %é a sala 123 (edifício 1, piso 2, 3ª sala no piso). Da mesma forma, a sala marcada com a $sala 235 e a @sala 312.

• Prédios, pisos e "enésima sala no andar" são sempre indexados em 1.

A entrada consistirá em um hotel ASCII com um quarto individual substituído por um asterisco ( *). Esta é a sala para a qual você deve enviar o número da sala. A entrada deve ser tomada como uma única sequência, mas você pode usar vírgulas como separadores de linha em vez de novas linhas (caso o seu idioma de escolha não possa receber entrada com várias linhas ou se for mais curto para receber uma linha). Opcionalmente, você pode exigir uma vírgula / nova linha à direita. Você também pode preencher linhas com espaços à direita para tornar a entrada um retângulo completo.

Como esse é o código-golfe , o código mais curto em bytes vence.

Demonstração

Isso usa um truque de golfe que eu nunca usei antes: Atribuir a uma variável ( K) dentro de uma função ( y) para salvar um resultado parcial dessa função.

Explicação:

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)}

Exemplo:

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

Eu gostei desse desafio! Se uma lista Python estiver ok como entrada (consulte exemplos de testes para exemplos), esta solução funcionará.

Editar 05-01-2016: adicionada uma linha (10 caracteres) para dividir a sequência em várias linhas.

Breve explicação:

• t é a linha na qual a sala está localizada (contada a partir da linha superior como índice da matriz = 0);
• i é o índice da sala em sua linha;
• o edifício é calculado como o número de espaços em branco duplos na linha inferior até i;
• floor é o número de linhas menos t;
• room é o índice do primeiro espaço em branco duplo na sequência invertida iaté o início do andar com a sala, anexado por um espaço em branco para cobrir o caso em que a sala está no primeiro edifício.

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))

Eu roubei a ideia de mesclagem de valor do ecatmur, mas as mesclei de uma maneira bem diferente ( economiza 8 bytes no final ). Isso também faz a mesma suposição de que EOF == -1.

A entrada é obtida de stdin e não deve ter espaços em branco ou novas linhas após a última construção na última linha; portanto, uma entrada de exemplo seria:

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

Demolir:

// 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
