code golf - Fifty Shades of Grey - Programming Puzzles & Code Golf Stack Exchange

Boys and girls are excited to see Fifty Shades of Grey on the silver screen, we just want to code without being bothered, so here's a challenge to pick our brain.

然後要求如下：

• Print on the screen fifty squares filled each with a different shade of grey
• If your language of choice lacks image processing capabilities, you could output an image file
• Squares must be visible, at least 20 x 20 pixels
• You can not use random numbers unless you make sure each shade is unique.
• You can not connect to any service over any network
• You can not read any files in your program.
• You can not use any libraries out of the standard libraries of your language of choice.

目前最多人按讚的是 Mathematica 寫的版本，只花 30 chars

ArrayPlot[#+5#2&~Array~{5,10}]  

ArrayPlot[5#+#2&~Array~{10,5}]  

其他還有：

• CJam - 23 chars

• Mathematica - 34 chars

• Java - 180 chars

import java.awt.*;void f(){new Frame(){public void paint(Graphics g){for(int i=1;i<51;g.setColor(new Color(328965*i)),g.fillRect(i%8*20,i++/8*20,20,20))setSize(600,600);}}.show();}  

• R - 35 chars

symbols(x,,,x<-50:99,bg=gray(x/99))  

• ipython 2 - 54 chars

t=arange(50);c=t/50.;scatter(t%5,t,500,zip(c,c,c),'s')  

• ipython 2 - 61 chars

• C++ - 93 chars

#include <cstdio>  
int main(){for(int i=51;i--;)printf("\e[48;2;%i;%i;%im ",i,i,i);}  

• C - 58 chars

main(i){for(i=51;i--;)printf("\e[48;2;%i;%i;%im ",i,i,i);}  

• JavaScript - 72 chars

for(i=90;i>40;)document.write('<font color=#'+i+i+i--+' size=7>&#9632;')  

• JavaScript - 70 chars

for(i=60;--i>9;)document.write('<font color='+i+i+i+' size=7>&#9632;')  

一大堆... 剩下懶得看了XDD
好多沒看過的語言啊...
是說原來這種比誰寫的 code 短的比賽方式叫 Code Golf 呀
