面临的挑战是生成类似于StackOverflow徽标的图像：

输出必须包含：

• 图片尺寸64 * 64或更大
• 灰色| __ | 异型底座
• 从底部向上弯曲的分段堆栈。这些片段将从灰色逐渐变为橙色，并向右转90度。段数应在5到7之间，最好是6。

注意：对于缺少颜色的ascii显示器，请使用'0'字符表示灰色，并使用'9'表示橙色。“ 1”到“ 8”将代表它们之间的阴影。

限制条件：

• 您必须生成图像。禁止加载图像或将其存储在代码/二进制文件中。

附加规则/信息：

• 图像不必与徽标相同，但是必须能够识别。
• 显示方法由您决定。将其保存到图像文件或显示在屏幕上都是可以接受的。

评审/获奖标准：

• 图像的准确性是首要条件
• 优雅是次要条件

Mathematica

Graphics[{
   Gray, Rectangle[{0, 0}, {78, 50}],
   White, Rectangle[{9, 9}, {69, 50}]}
  ~Join~
  Table[{
    Blend[{Gray, Orange}, x/5],
    Rotate[
     Translate[
      Rectangle[{16, 16}, {61, 25}],
      {0.25x^3 + 0.6x^2 - 0.4x, -0.53x^3 + 3.26x^2 + 12x}],
     -0.05x^2 - 0.04x]},
   {x, 0, 5}]]

在意识到这不是代码高尔夫之后，我决定美化自己的答案。哎呀！

屏幕截图：

在相关新闻中，我还创建了我认为Stack Overflow徽标在...中可能看起来像的东西：未来：

如果有人想玩的话，下面是代码（很抱歉）：

Graphics3D[{EdgeForm[],
   Opacity[1],
   RGBColor[0.2, 0.2, 0.2], Cuboid[{0, 0, 0}, {78, 4, 50}],
   Cuboid[{0, 4, 0}, {4, 45, 50}],
    Cuboid[{74, 4, 0}, {78, 45, 50}],
   Opacity[1]}
  ~Join~
  Fold[Join, {},
   Table[{Hue[0.15 - i/5/12, i/3, 1],
     Translate[
      Rotate[
       Scale[Cuboid[{16, 16, 16}, {61, 25, 25}], {1, .3, .3}],
       (-.05 ((i*2 - 1.5)*1.25)^2 - .04 ((i*2)*1.2)), {0.3, 
        0.8, -1}, {(16 + 61)/2, (16 + 25)/2, (16 + 25)/2}],
      {-((i*2)^2 - (i*2)*4)/2, (i*2)^2*3/2, 0}]},
    {i, 0, 4.5, 0.05}]], Lighting -> "Neutral", Axes -> False, 
 Background -> White, Boxed -> False]

Javascript（650）

我写了一个quine来读取函数中的字符，并用0-9之间的数字替换非空格字符。

(function a(){
l=[
                   1,
                    1,
            11,      1,
             11,     1,
               11,    1,
       11,      11,   1,
         11,      11,
           11,
   11,       1111,
     1111,
0,       11111111, 0,
0, 11,             0,
0,   111111111111, 0,
0,                 0,
0, 11111111111111, 0,
0,                 0,
000000000000000000000]

b=a.toString().split("[")[1].split("]")[0].split(""),i=-1
document.getElementById("output").innerHTML=
b.map(function(c){
++i
if(c==" "||c=="\n")return c
if(c!=0)c=9-Math.floor((i/b.length)*10)
if(b[i-1]=="0")c=0
return"<span class='c"+c+"'>"+c+"</span>"
}).join("")
})()

这将输出以下ASCII文字：

                   99
                    88
            888      88
             777     77
               766    66
       666      666   66
         555      555
           555
   444       44444
     44444
00       333333333 00
00 333             00
00   2222222222222 00
00                 00
00 111111111111111 00
00                 00
000000000000000000000

如果愿意，可以使用CSS样式表上色

  span{
    font-weight: bold;
  }
  .c0, .c1{
    color: #222;
  }
  .c2{
    color: #765;
  }
  .c3{
    color: #976;
  }
  .c4{
    color: #A64;
  }
  .c6, .c5{
    color: #D51;
  }
  .c8, .c9, .c7{
    color: #F60;
  }

您可以在jsBin上看到它。

SVG（347个字符）

基于Sir_Lagsalot的版本，用笔触代替填充。除了减少一些字符外，代码更简单，输出看起来也更好地扩大了规模。

渲染为PNG（以自然大小并按比例放大x2和x3）：

编辑：最终解决了导致框的侧面不对齐的“ by-by-one”错误。还稍微调整了线的粗细和端点的位置，并增加了显式的宽度和高度，以避免底部和右侧边缘被裁剪得过紧。现在看起来很多接近官方标志。

具有光泽的Haskell

import Graphics.Gloss

picture = translate 0 (-50) $ pictures [stack, base 150 60 20]

stack = translate 0 30 $ pictures [item n | n <- [0..5]]

item n = bend 200 (-10*n) $ color (fade grey orange (n/5)) box
  where box = rectangleSolid 110 20

base width height thickness = color grey $ pictures [left, right, bottom]
  where bottom = rectangleSolid width thickness
        left = translate (width / 2) (height / 2) side
        right = translate (-width / 2) (height / 2) side

        side = rectangleSolid thickness (height + thickness)

bend radius angle = translate radius 0 . rotate angle . translate (-radius) 0

fade from to alpha = mixColors (1-alpha) alpha from to

grey = greyN 0.5

将代码粘贴到此处以查看实际效果，或添加以下行对其进行编译（需要Gloss）。

main = display (InWindow "Stack Overflow" (512, 512) (10, 10)) white picture

SVG（333个字符）

我创建了一个SVG图片，该图片会生成333个字符的徽标的67x68版本：

例：

JavaScript + jQuery和SVG-250

$('body').html('<svg><g stroke-width="6" fill="none"$grey" d="m3,51v31h47V53M10,70h33"/$#a86" d="m10,57 33,3"/$#b95" d="m13,42 31,9"/$#c82" d="m20,25 28,17"/$#e80" d="m34,9 19,27"/$#f71" d="m56,1 4,32"/></g></svg>'.replace(/\$/g, '><path stroke="'))​

我使用了Ilmari Karonen的SVG，并使用JavaScript替换了$s，><path stroke="从而有效地缩短了s，即使有JavaScript的开销。

[R

不是最漂亮的解决方案，但它返回请求的输出。

library(grid)
my.palette <- colorRampPalette(c("grey57","orange"))(6)
png("StackOverflow_Logo.png", width=300, height=300)
pushViewport(viewport(x=0.5, y=0.5, w=unit(100, "points"), h=unit(100, "points")))
grid.polygon(x=unit(c(10, 0, 0, 100, 100, 90, 90, 10),"points"), 
             y=unit(c(50, 50, 0, 0, 50, 50, 10, 10),"points"),
             default.units="points", gp=gpar(col = "grey57", fill="grey57"))
