A Grande Pirâmide de Gizé, a maior pirâmide do Egito, não é apenas a mais antiga das Sete Maravilhas do Mundo Antigo, mas é também a única a permanecer praticamente intacta. As pirâmides egípcias podem levar até 20 anos para serem construídas e são tão grandes que Al-Aziz Uthman, filho do grande Saladino que esmagou os cruzados, teve que desistir de demolir as grandes pirâmides de Gizé porque foi considerada uma tarefa muito grande . As pirâmides egípcias foram construídas principalmente como túmulos para os faraós do país e seus consortes durante os períodos do Reino Antigo e Médio (c. 2686-1690 aC) e, a partir de 2008, 138 pirâmides egípcias foram descobertas.

A tarefa é criar um programa que insira uma sequência de distâncias separadas por um espaço e produza pirâmides de texto 10 × 10 separadas por essas distâncias. Uma distância de 1 é igual a dois caracteres.

Uma pirâmide de texto ficará assim:

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

Se a entrada consistir apenas em uma quebra de linha, uma pirâmide será produzida, como acima . Para cada pirâmide, as pirâmides à esquerda são exibidas como se estivessem na frente.

O aplicativo para atender a esses requisitos com a menor quantidade de caracteres é o vencedor.

Referência: Wikipedia.org

Golfscript, 70 caracteres

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

Porta direta da minha solução Ruby , por isso tenho certeza de que é possível reduzi-la em alguns 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]})}

Script de teste .

A entrada aleatória também cria boas imagens:

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

Estou bastante insatisfeito com isso! Parece muito longo. Ideias?

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}

Versão ligeiramente mais curta, que recebe a entrada como argumentos da linha de comando e não do 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}

Não posso acreditar que ninguém fez uma solução regex ainda. Perl está longe de ser minha melhor linguagem, então isso provavelmente pode perder muito mais. Eu estaria interessado em ver uma implementação sed, se alguém estiver pronto para o desafio.

(Obrigado, @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}

Não vou ganhar com JavaScript, mas agora há uma entrada de JavaScript :)

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

Rubi (112)

Um pouco menor que a solução Ruby da Ventero, com uma abordagem diferente. Comecei a aprender Ruby, então isso provavelmente pode ser bastante reduzido.
