任务

给定一个非空的小写ASCII字母字符串a- z，请使用第一个字符，并：

  • 用第二个字符的副本方块围住它，
  • 用第三个角色的副本菱形包围它，
  • 用第四个字符的副本方块围住…

…在正方形和菱形边框之间交替，直到字符串结尾。边框之间的空白应由ASCII空格（）表示。

要添加正方形边框，请在整个当前“工作数组”周围精确绘制一个正方形：

要添加菱形边框，请绘制居中的菱形形状，该形状以对角线而不是正交的方式接触最外面的正方形：

                                                     s

您的程序必须输出最终数组。

  • 每行可以包含任意数量的尾随空格。
  • 您可以输出代表行的字符串列表，也可以输出一个单独的以换行符分隔的字符串，并带有可选的尾随换行符。
  • 前导/尾随的空白行是不允许的。
  • 也不允许前导空格。

这是代码高尔夫球。以字节为单位的最短代码获胜。

上述实施例是预期的输出，用于cat，cats，meow，和meows，在读取顺序。其他一些值得处理的情况：

  • 对于输入a，您的程序应输出：

我在这个网站上的第一个高尔夫。将输入字符串传递给函数f，例如f('codegolf')

f=s=>{N=n=>(2<<n/2+.5)-3-n%2
D=N(l=s.length)
for(a=[],i=S=D*2+1;i--;)a[i]=a[S+~i]=Array(S).fill` `
for(;l--;)for(o=n=N(l+1),I=0;I<=n;I++,o-=~l&1)a[y=D+I][x=D+o]=a[x][y]=a[y][D-o]=a[x][D-I]=s[l]
return a.map(r=>r.join``)}

-6个字节，感谢@Sunny Pun：传递模板字符串时，请删除括号。

@ETHproductions -2个字节：更改S-i-1为S+~i，更改l%2||o--为o-=~l&1。

@Sunny Pun，@ edc65的每个建议为-18个字节：删除prompt()并console.log()支持函数格式，请勿.join()最终确定字符串数组

我数了256个字节。您是否有可能将换行符计数为每个（\r\n）两个字节，而不是一个（\n）？

使其成为函数应通过删除prompt和来节省字节console.log。您也可以使用模板字符串，这样可以在每个函数调用上为字符串节省2个字节（如fill(' ')变为fill` `）

欢迎来到PPCG！用什么其他人说一起去，可以缩短S-i-1到S+~i，并i%2||o--到o-=~i&1。
— ETHproductions 2016年
@Mego重新检查计数，正确为256。谢谢！

我认为a=Array(D*2+1).fill .map((_,$,a)=>[...a])可以为您节省10个字节。

注意：此解决方案将点（'。'）用作“空格”字符，以使空白更加明显。要使用空格，必须将更S(s,46)改为S(s,32)。分数保持不变。

如何使用：

include<iostream>

void printSquare(std::string word){
    auto result = f(word);
    for(auto& s:result)
        std::cout << s << std::endl;
    std::cout << std::endl << std::endl;
}

int main() {
    printSquare("a");
    printSquare("ab");
    printSquare("cat");
    printSquare("cats");
    printSquare("meow");
    printSquare("meows");
    printSquare("codegolf");
    return 0;
}

输出：
