斜线绘图

23

编写一个程序，它在文本的矩形块组成X的和.的，像这样的粗糙A：

......
..XX..
.X..X.
.XXXX.
.X..X.
.X..X.

通过绘制斜线（视上下文而定是向前还是向后），在网格的X边框a .或边的任何地方（其余部分都填满空格），输出此网格的表示，逆时针旋转45度：

 /\/\
/ /\ \
\/ /  \
/\/ /\ \
\  /  \/
 \ \
  \ \
   \/

只要X输入中的'的形状由斜杠保持，则尾随和前导空格（和换行符）的数量无关紧要。可以修剪的额外行或列.。

对于I / O，您可以使用stdin / stdout / files /命令行参数的任意组合。例如，您的脚本可能会使用X.模式的文件名，并使用斜杠模式重写该文件。否则您的脚本可能会X.逐行从stdin 接受模式（d完成后按），然后将结果输出到stdout。

输入可能会很大，但您可能会认为它总是格式正确。

除/ \输出字符和换行符外，任何输出均不应包含字符。

计分

以字节为单位的最短代码获胜。如果使用非ASCII字符，请使用https://mothereff.in/byte-counter作为字节计数器。

奖励：如果您可以在程序中更改（替换而不是删除）一个字符，则减去50个字节，以便输出顺时针旋转45度的斜杠网格，例如：

   /\/\
  / /\ \
 /  \ \/
/ /\ \/\
\/  \  /
    / /
   / /
   \/

Python 2-236、228、226、221、250、248 246-50 = 196

s=input().split()
s=zip(*s[::-1])
X=len(s[0])+2
d=('.',)
B=[d*X]
s=B+[d+tuple(l)+d for l in s]+B
Y=len(s)
for x in range(X,-Y,-1):print' '*abs(x)+''.join(' \\'[s[y-1][x+y-1]!=s[y-1][x+y]]+' /'[s[y-1][x+y]!=s[y][x+y]]for y in range(1,Y)if 0<x+y<X)

我添加了可选的奖励功能，该功能可将方向从顺时针方向更改为逆时针方向。基本上，第二行只是将输入旋转90度。要在两个选项之间切换，请用s=zip(...)类似的替换（例如，S=zip(...)分配给不再使用的变量）。

MATLAB-286-50 = 236

缩小：

S=input('');x=rot90(reshape(input('','s'),S),1);S=size(x);D=sum(S);[r,c]=ind2sub(S,find(x==88));A=zeros(D);f=@(o,p)sub2ind([D D],r+c+o-1,c-r+S(1)+p);A(f(1,1))=1;t=f(0,0);A(t)=A(t)+1;A(f(1,0))=3;t=f(0,1);A(t)=A(t)+3;fprintf('%s',char([(1-mod(A,2))*32+(A==1)*47+(A==3)*92,ones(D,1)*13]'))

展开：

S = input('');
x = rot90( reshape( input('','s'), S ), 1 );
S = size( x );
D = sum( S );
[r,c] = ind2sub( S, find( x==88 ) );
A = zeros( D );
f = @(o,p) sub2ind( [D D], r+c+o-1, c-r+S(1)+p );

A(f(1,1)) = 1;
t = f(0,0); A(t) = A(t)+1;
A(f(1,0)) = 3;
t = f(0,1); A(t) = A(t)+3;

fprintf( '%s', char( [(1-mod( A, 2 ))*32 + (A==1)*47 + (A==3)*92, ones( D, 1 )*13]' ) )

通过消除强制类型转换char，可以将代码进一步减少6个字符（以绑定当前引线），但这会导致MATLAB发出警告，我不确定是否允许这样做。

如果要求输入具有“标记”格式（例如）['X..';'.X.';'..X']，则可以再减少13个字符，但是我也不认为这也是允许的。当前，脚本仅接受两个数字（行和列的维数），然后读取单个字符串的网格字符。

奖金

通过将1调用x = rot90( ..., 1 );中的0更改为a ，转换将从CCW 45°旋转更改为CW 45°旋转。实际上，通过将此参数从步进0到，所有可能的45°+ n·90°旋转都是可能的3。

样本输出：

XXX...XXX....XXX...XXX
X..X..X..X..X.....X...
XXX...XXX...X.....X.XX
X.....X.....X.....X..X
X.....X......XXX...XXX
