La Grande Piramide di Giza, la più grande piramide dell'Egitto, non è solo la più antica delle sette meraviglie del mondo antico, ma è anche l' unica a rimanere in gran parte intatta. Le piramidi egiziane possono richiedere fino a 20 anni per essere costruite e sono così grandi che Al-Aziz Uthman, figlio del grande Saladino che ha schiacciato i crociati, ha dovuto rinunciare a demolire le grandi piramidi di Giza perché era considerato un compito troppo grande . Le piramidi egiziane furono in gran parte costruite come tombe per i faraoni del paese e le loro consorti durante i periodi del Vecchio e Medio Regno (2686-1690 a.C. circa), e dal 2008 sono state scoperte 138 piramidi egiziane.

Il compito è creare un programma che inserisca una sequenza di distanze separate da uno spazio e produca piramidi di testo 10 × 10 separate da quelle distanze. Una distanza di 1 equivale a due caratteri.

Una piramide di testo sarà simile a questa:

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

Se l'input è costituito solo da un'interruzione di riga, verrà prodotta una piramide, come sopra . Per ogni piramide, le piramidi a sinistra vengono visualizzate come se fossero di fronte.

La domanda per soddisfare questi requisiti nel minor numero di personaggi è il vincitore.

Riferimento: Wikipedia.org

Golfscript, 70 caratteri

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

Porta diretta della mia soluzione Ruby , quindi sono sicuro che è possibile accorciarlo di alcuni caratteri.

Windows PowerShell, 122 132 133 139

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

Test script .

L'input casuale rende anche belle immagini:

Haskell, 148 caratteri

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

Non sono abbastanza soddisfatto di questo! Sembra troppo lungo. Idee?

Python, 123 caratteri

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 caratteri

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 caratteri

$_=<>;$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}

Versione leggermente più corta che accetta input come argomenti della riga di comando anziché da 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}

Non riesco a credere che nessuno abbia ancora fatto una soluzione regex. Perl è ben lungi dall'essere la mia lingua migliore, quindi probabilmente questo può perdere molto di più. Sarei interessato a vedere un'implementazione di sed, se qualcuno è pronto per la sfida.

(Grazie, @mbx, per 4 caratteri).

JavaScript, 396 byte

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}

Non ho intenzione di vincere con JavaScript, ma ora c'è una voce JavaScript :)

Utilizzo: _("1 2 3")ecc.

Rubino (112)

Leggermente più breve della soluzione Ruby di Ventero, con un approccio diverso. Ho appena iniziato a studiare Ruby, quindi probabilmente questo può essere ridotto abbastanza.

s=' '*9+r='/\\';gets.split.map{|i|s+=' '*2*(i.to_i-1)+r}
10.times{puts s;s.gsub!' /','/-';s.gsub!(/\\.?/,'-\\')}
