La Gran Pirámide de Giza, la pirámide más grande de Egipto, no solo es la más antigua de las Siete Maravillas del Mundo Antiguo, sino que también es la única que permanece en gran parte intacta. Las pirámides egipcias pueden tardar hasta 20 años en construirse y son tan grandes que Al-Aziz Uthman, hijo del gran Saladino que aplastó a los cruzados, tuvo que renunciar a demoler las grandes pirámides de Giza porque se consideró una tarea demasiado grande . Las pirámides egipcias se construyeron principalmente como tumbas para los faraones del país y sus consortes durante los períodos del Imperio Antiguo y Medio (c. 2686–1690 a. C.), y hasta 2008, se descubrieron 138 pirámides egipcias.

La tarea es crear un programa que ingrese una secuencia de distancias separadas por un espacio y produzca pirámides de texto de 10 × 10 separadas por esas distancias. Una distancia de 1 es igual a dos caracteres.

Una pirámide de texto se verá así:

         /\
        /--\
       /----\
      /------\
     /--------\
    /----------\
   /------------\
  /--------------\
 /----------------\
/------------------\

Si la entrada consiste solo en un salto de línea, se producirá una pirámide, como se indicó anteriormente . Para cada pirámide, las pirámides a la izquierda se muestran como si estuvieran delante.

Ejemplo I

Salida:

    /----------\-------\-----\-\
   /------------\-------\-----\-\
  /--------------\-------\-----\-\
 /----------------\-------\-----\-\
/------------------\-------\-----\-\

Ejemplo II

Salida:

       /----\            /----\
      /------\          /------\
     /--------\        /--------\
    /----------\      /----------\
   /------------\    /------------\
  /--------------\  /--------------\
 /----------------\/----------------\
/------------------\-----------------\

Ejemplo III

Entrada:

         /\                    /\
        /--\                  /--\
       /----\                /----\
      /------\              /------\

La aplicación para cumplir estos requisitos en la menor cantidad de caracteres es la ganadora.

Golfscript, 70 caracteres

~]0-:|;10,{:§9\-" "*"/""-"§2**+"\\"+:&|{.§>{§-(2*" "*1$}{-2*&>}if}%n}%

Puerto directo de mi solución Ruby , así que estoy seguro de que es posible acortar esto en bastantes caracteres.

Windows PowerShell, 122 132 133 139

$d=@(-split$input)-gt0
0..9|%{' '*(9-($x=$_))+($a="/$('--'*$_)\")+-join($d|%{'  '*(($_-$x-1)*($x-lt$_))
$a[(-2*$_)..-1]})}

Prueba de guión .

La entrada aleatoria también hace buenas imágenes:

Haskell, 148 caracteres

r=replicate
p d=map(\k->foldr(\n i->r(9-k)' '++'/':r(2*k)'-'++"\\"++drop(11+k)(r(2*n)' '++i))""$d++[0])[0..9]
main=interact$unlines.p.map read.words

¡Estoy bastante insatisfecho con esto! Simplemente se siente demasiado tiempo. Ideas?

Python, 123 caracteres

N=[10]+map(int,raw_input().split())
for y in range(10):print''.join((2*n*' '+'/'+2*y*'-'+'\ ')[-2*n-1:-1]for n in N)[9-y:]

Ruby 1.9, 116 caracteres

d=gets.split-[?0]
10.times{|i|puts [?\s*(9-i),l=?/+?-*2*i+?\\,d.map{|r|i<(r=r.to_i)??\s*2*(r+~i)+l :l[-2*r,99]}]*""}

Perl, 130 126 132 caracteres

$_=<>;$s=" "x9;map{$k.="/\\"."  "x($_-1)if$_}split;$_="$s$k/\\$s\n";for$i(0..9){print;s%\\-%-\\%g;s%\\/%-\\%g;s%\\ %-\\%g;s% /%/-%g}

Versión ligeramente más corta que toma la entrada como argumentos de línea de comandos en lugar de desde stdin:

$s=" "x9;map{$k.="/\\"."  "x($_-1)if$_}@ARGV;$_="$s$k/\\$s\n";for$i(0..9){print;s%\\-%-\\%g;s%\\/%-\\%g;s%\\ %-\\%g;s% /%/-%g}

No puedo creer que nadie haya hecho una solución regex todavía. Perl está muy lejos de ser mi mejor idioma, por lo que esto probablemente puede perder mucho más. Me interesaría ver una implementación sed, si alguien está preparado para el desafío.

(Gracias, @mbx, por 4 caracteres).

JavaScript, 396 bytes

function p(a){for(u=0;u<10;u++){t[u+a][9-u]="/";for(k=9-u+1+a;k<10+u+a;k++)t[k][u]="-";
t[10+u+a][u]="\\"}}function _(a){t=[];for(i=0;i<50;i++){t[i]=[];for(j=0;j<10;j++)t[i][j]=" "
}var a=a.split(" "),b=a.reduce(function(a,b){return a-0+(b-0)})*2;for(i=a.length-1;i>=0;
i--)p(b),b-=a[i]*2-0;p(0);a="";for(j=0;j<10;j++){b="";for(i=0;i<50;i++)b+=t[i][j];
a+=b.replace(/\s+$/,"")+(j<9?"\n":"")}return a}

No voy a ganar con JavaScript, pero ahora hay una entrada de JavaScript :)

Uso: _("1 2 3")etc.

Rubí (112)

Ligeramente más corto que la solución Rubí de Ventero, con un enfoque diferente. Acabo de empezar a aprender Ruby, por lo que probablemente esto se pueda reducir bastante.
