46 个字符,从标准输入读取。

(,.~,~[,.~' '$~#,#)^:(<:".1!:1]3)' /\',:'/__\'

\n 总是分隔句子,这使得它不可能放入 S3 中(只有 54 个字符可供使用)。 S4 162 有点大,所以我填充了它以适合。偶然的是,/\ 是一个合法的副词。 ☺

               /\
              i=:3
             /\  /\
            %r=:1!:1
           /\      /\
          t=:]    [r+i
         /\  /\  /\  /\
        b=:' /\',:'/__\'

      i=:1            -".t
     /\  /\          /\  /\

46 characters, reading from stdin.

(,.~,~[,.~' '$~#,#)^:(<:".1!:1]3)' /\',:'/__\'

\n always delimits sentences, which made it impossible to fit inside S3 (only 54 characters to play with). S4 is a bit big at 162, so I padded it to fit. Serendipitously, /\ is a legal adverb. ☺

               /\
              i=:3
             /\  /\

抱歉我来晚了。这是基于 A. Rex 的 Perl 解决方案:

                           &I                               
                          ;for                              
                         $x  (2                             
                        ..<>){$E                            
                       .=      $E                           
                      ;my$    y;3*

空格都很重要。

使用gofmt sierpinski-3.go 取消最小化 | perl -p -e's/\t/ /g'

package main

import (

    "os";
    "strconv";
)

func main() {

    n, _ := strconv.Atoi(os.Args[1]);

    N := a << uint(n);
    for N > 0 {
        N -= 2;
        for k := 0; k < 2; k++ {

                if b&1 == 0 {

                b >>= 1;

            fmt.Print("\n");
        }
        a ^= a * 2;
    }
}

我得到了关于围棋高尔夫的一个很好的提示 这里

Whitespace is all significant.

Perl,82 笔画

此版本不再打印尾随换行符。只有第一个换行符是必要的:

$_=' /\ 
/__\\';
for$x(2..<>){
my$y;
$".=$";
s#.+#$y.=$/.
amp;x2,$".
amp;.$"#ge;
$_.=$y
}
print

如果允许命令行切换,那么根据传统的 Perl 高尔夫评分,这是 77+3 杆(第一个换行符是字面意思):

#!perl -p
$\=' /\ 
/__\\';
$y="",
$".=$",
$\=~s#.+#$y.=$/.
amp;x2,$".
amp;.$"#ge,
$\.=$y
for 2..$_

如果您发现改进,请随时编辑我的答案。

Perl, 82 strokes

This version no longer prints a trailing newline. Only the first newline is necessary:

$_=' /\ 
/__\\';
for$x(2..<>){
my$y;
$".=$";
s#.+#$y.=$/.
amp;x2,$".
amp;.$"#ge;
$_.=$y
}
print

If command-line switches are allowed, then by traditional Perl golf scoring, this is 77+3 strokes (the first newline is literal):

#!perl -p
$\=' /\ 
/__\\';
$y="",
$".=$",
$\=~s#.+#$y.=$/.
amp;x2,$".
amp;.$"#ge,
$\.=$y
for 2..$_

Please feel free to edit my answer if you find an improvement.

Haskell,153 149 137 125 118 112个字符:

使用尾递归:

(%)=zipWith(++)
p="  ":p
g t _ 1=t
g t s(n+1)=g(s%t%s++t%t)(s%s)n
main=interact$unlines.g[" /\\ ","/__\\"]p.read

更早版本,@118 个字符:

(%)=zipWith(++)
f 1=[" /\\ ","/__\\"]
f(n+1)=s%t%s++t%t where t=f n;s=replicate(2^n)' ':s
main=interact$unlines.f.read

使用(刚刚被弃用!)n+k 模式 保存了 4 个字符。

我喜欢它的可读性,即使是压缩形式。

编辑:旧主

main=do{n<-getLine;putStr$unlines$f$read n}

Haskell, 153 149 137 125 118 112 characters:

Using tail recursion:

(%)=zipWith(++)
p="  ":p
g t _ 1=t
g t s(n+1)=g(s%t%s++t%t)(s%s)n
main=interact$unlines.g[" /\\ ","/__\\"]p.read

earlier version, @118 characters:

(%)=zipWith(++)
f 1=[" /\\ ","/__\\"]
f(n+1)=s%t%s++t%t where t=f n;s=replicate(2^n)' ':s
main=interact$unlines.f.read

Using the (justly deprecated!) n+k pattern saved 4 characters.

I like how it comes out halfway readable even in compressed form.

edit:old main

main=do{n<-getLine;putStr$unlines$f$read n}

MATLAB - 64 个字符(脚本版本)

这假设您已在工作区中定义了变量 N

A=[' /\ ';'/__\'];for i=1:N-1,B=32*ones(2^i);A=[B A B;A A];end;A

MATLAB - 78 个字符(m 文件函数版本)

N 传递为函数 s 的参数:

function A=s(N),A=[' /\ ';'/__\'];for i=1:N-1,B=32*ones(2^i);A=[B A B;A A];end

MATLAB - 64 characters (script version)

This assumes that you have the variable N already defined in your workspace:

A=[' /\ ';'/__\'];for i=1:N-1,B=32*ones(2^i);A=[B A B;A A];end;A

MATLAB - 78 characters (m-file function version)

Pass N as an argument to the function s:

function A=s(N),A=[' /\ ';'/__\'];for i=1:N-1,B=32*ones(2^i);A=[B A B;A A];end

C

Perl 答案,但重量较重,有 131 个必要字符。

a,b;main(c,v)char**v;{c=1<<atoi(v[1]);for(a=0;a<c;a++,puts(""))
for(b=c;b--;write(1,b&~a?"    ":a&1?"/__\\":" /\\ ",4-2*(b>a)))--b;}

我以为 write(1,…) 是 UNIX API,但这似乎在 Windows 上也可以正常编译和运行。

如果将 char 替换为 int,它会保存一个字符并且仍然有效,但其合法性值得怀疑。

C

Same algorithm as the Perl answer, but weighing in heavier, at 131 necessary characters.

a,b;main(c,v)char**v;{c=1<<atoi(v[1]);for(a=0;a<c;a++,puts(""))
for(b=c;b--;write(1,b&~a?"    ":a&1?"/__\\":" /\\ ",4-2*(b>a)))--b;}

I thought write(1,…) was UNIX API, but this seems to compile and run fine on Windows too.

If you replace char by int, it saves one character and still works, but it's of questionable legality.

徽标(不完全符合要求):47 个字符

to F:n if:n[repeat 3[F(:n-1)fd 2^:n rt 120]]end

我仅使用 http://www.calormen.com 对此进行了测试/Logo/ 所以我不知道它是否是便携式的。它不符合要求,但徽标肯定是这里合适的语言吗? :) 我喜欢在编写徽标时比 Golfscript 和 J 少一个字符。

Logo (not exactly following the requirements): 47 characters

to F:n if:n[repeat 3[F(:n-1)fd 2^:n rt 120]]end

I tested this only with http://www.calormen.com/Logo/ so I don't know if it's portable. It doesn't follow the requirements, but surely logo must be the appropriate language here? :) I love that at the time of writing logo is one character short of equalling golfscript and J.
