La Grande Pyramide de Gizeh, la plus grande pyramide d'Egypte, est non seulement la plus ancienne des sept merveilles du monde antique, mais elle est également la seule à rester en grande partie intacte. Les pyramides égyptiennes peuvent prendre jusqu'à 20 ans à construire et sont si grandes qu'Al-Aziz Uthman, fils du grand Saladin qui a écrasé les croisés, a dû renoncer à démolir les grandes pyramides de Gizeh parce que cela était considéré comme une tâche trop lourde . Les pyramides égyptiennes ont été principalement construites en tant que tombes pour les pharaons du pays et leurs épouses pendant les périodes de l'Ancien et du Moyen Empire (c. 2686–1690 avant notre ère), et en 2008, 138 pyramides égyptiennes ont été découvertes.

La tâche consiste à créer un programme qui saisit une séquence de distances séparées par un espace et produit des pyramides de texte 10 × 10 séparées par ces distances. Une distance de 1 équivaut à deux caractères.

Une pyramide de texte ressemblera à ceci:

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

Si l'entrée se compose uniquement d'un saut de ligne, alors une pyramide sera produite, comme ci-dessus . Pour chaque pyramide, les pyramides à gauche sont affichées comme si elles étaient devant.

La candidature pour remplir ces conditions avec le moins de caractères est gagnante.

Référence: Wikipedia.org

Golfscript, 70 caractères

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

Port direct de ma solution Ruby , donc je suis sûr qu'il est possible de raccourcir cela de quelques caractères.

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 test .

L'entrée aléatoire donne également de belles images:

Haskell, 148 caractères

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

Je suis assez insatisfait de ça! Cela semble trop long. Des idées?

Python, 123 caractères

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 caractères

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, 130 126 132 132 caractères

$_=<>;$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}

Version légèrement plus courte qui prend l'entrée comme arguments de ligne de commande plutôt que depuis 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}

Je ne peux pas croire que personne n'ait encore fait de solution regex. Perl est loin d'être ma meilleure langue, donc cela peut perdre beaucoup plus. Je serais intéressé de voir une implémentation sed, si quelqu'un est prêt à relever le défi.

(Merci, @mbx, pour 4 caractères).

JavaScript, 396 octets

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}

Je ne vais pas gagner avec JavaScript, mais il y a maintenant une entrée JavaScript :)

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

Rubis (112)

Légèrement plus courte que la solution Ruby de Ventero, avec une approche différente. Je viens de commencer à apprendre Ruby, donc cela peut probablement être réduit un peu.
