字母模式匹配

19

我们遇到了很多字母挑战。对于此挑战，您将传递字母挑战的输出，并且需要输出按比例缩放的模式N。

例如，如果N=5和您通过了L-phabet：

ABCDEFGHIJKLMNOPQRSTUVWXYZ
BBCDEFGHIJKLMNOPQRSTUVWXYZ
CCCDEFGHIJKLMNOPQRSTUVWXYZ
DDDDEFGHIJKLMNOPQRSTUVWXYZ
EEEEEFGHIJKLMNOPQRSTUVWXYZ
FFFFFFGHIJKLMNOPQRSTUVWXYZ
GGGGGGGHIJKLMNOPQRSTUVWXYZ
HHHHHHHHIJKLMNOPQRSTUVWXYZ
IIIIIIIIIJKLMNOPQRSTUVWXYZ
JJJJJJJJJJKLMNOPQRSTUVWXYZ
KKKKKKKKKKKLMNOPQRSTUVWXYZ
LLLLLLLLLLLLMNOPQRSTUVWXYZ
MMMMMMMMMMMMMNOPQRSTUVWXYZ
NNNNNNNNNNNNNNOPQRSTUVWXYZ
OOOOOOOOOOOOOOOPQRSTUVWXYZ
PPPPPPPPPPPPPPPPQRSTUVWXYZ
QQQQQQQQQQQQQQQQQRSTUVWXYZ
RRRRRRRRRRRRRRRRRRSTUVWXYZ
SSSSSSSSSSSSSSSSSSSTUVWXYZ
TTTTTTTTTTTTTTTTTTTTUVWXYZ
UUUUUUUUUUUUUUUUUUUUUVWXYZ
VVVVVVVVVVVVVVVVVVVVVVWXYZ
WWWWWWWWWWWWWWWWWWWWWWWXYZ
XXXXXXXXXXXXXXXXXXXXXXXXYZ
YYYYYYYYYYYYYYYYYYYYYYYYYZ
ZZZZZZZZZZZZZZZZZZZZZZZZZZ

您需要输出：

ABCDE
BBCDE
CCCDE
DDDDE
EEEEE

为了便于说明，我将仅使用ABCD，而不使用完整的字母。 您需要能够匹配L-phabet（上方）以及以下模式：

单行：

ABCD    or     A
               B
               C
               D

单行重复N次数

ABCD    or    AAAA
ABCD          BBBB
ABCD          CCCC
ABCD          DDDD

该表格法：

ABCD
BCDA
CDAB
DABC

这个字母三角形：

A      or   AAAAAAA
AB           BBBBB
ABC           CCC
ABCD           D
ABC
AB
A

我们还有许多品种的半三角形：

A           AAAA      A        ABCD
BB          BBB       AB       ABC
CCC         CC        ABC      AB
DDDD        D         ABCD     A

最后，广场：

AAAAAAA
ABBBBBA
ABCCCBA
ABCDCBA
ABCCCBA
ABBBBBA
AAAAAAA

以上所有模式的大小均为4。但是，您将获得一个大小为26的模式（N介于1到26之间），并且需要缩放该模式。您不需要处理任何其他模式。

  • 1的输出将始终是单个字符 A
  • 26的输出将始终是传入的相同全尺寸图案。
  • 每行的末尾都可以使用尾随空格，末尾也可以使用尾随换行符
  • 您可以在这里找到所有尺寸为26的图案

这是一个代码高尔夫，所以请以尽可能少的字节来做！

您可以在某处提供全尺寸模式。

PHP，502字节

<?$c=count($x=explode("\n",$_GET[p]));for($t=$u=$o="",$f="substr",$n=0;$n<$g=$_GET["n"];$n++){if(2651==$l=strlen($s))$o.=$f($x[$n],0,$g).$f($x[$n],1-$g)."\n";elseif($l==1026)echo($t=$f($x[$n],0,$g)).$f(strrev($t),1)."\n";elseif($f($s,-1)=="Y")echo$f($x[$n],0,$g-$n).$f($x[$n],-$n,$n)."\n";elseif($l==376&&$f($s,-2,1)=="\n")echo$f($x[$n],0,$g-$n)."\n";elseif($l==726){$t.=$x[$n]."\n";$n+1==$g?:$u=$x[$n]."\n".$u;}else echo$f($x[$n]??"",0,$g)."\n";}if($o)echo$o.substr(strrev($o),2*$g+1);if($t)echo$t.$u;

与模式的字符串长度一起使用。模式具有这些条件。信始于末。CR被删除。

1）不必要引号："substr"，$_GET["n"]，"Y"（-6）。2）$x[$n]."\n"-> "$x[$n]\n"，$u（- 2）的类似物。3）我很确定您可以使用某种形式>进行<number>==$l比较（-4）。4）($n=0;$n<...;$n++)-> ($n=-1;++$n<...;)（-1）。5）if($o)是不必要的：如果$o为空，则strrev($o)及其子串也为空，因此不会打印任何内容（-6）。6）&&-> &（-1）。7）您真的需要空字符串代替substr的null吗？$x[$n]??""-> $x[$n]（-4 ）？

R，483412字节

    x=function(n){d=1:n;a=LETTERS[d];z=rep;f=function(...)cat(...,"\n",sep="");g=c(d,n:2-1);for(i in d)f(a[z(i,i)],if(i!=n)a[(i+1):n]);f(a);for(i in d)f(a[i]);for(i in d)f(a);for(i in d)f(z(a[i],n));for(i in d)f(a[i:n],if(i>1)a[1:i-1]);for(i in g)f(a[1:i]);for(i in d)f(z(" ",i-1),z(a[i],2*(n-i)+1));for(i in d)f(z(a[i],i));for(i in d)f(z(a[i],n-i+1));for(i in g)f(if(i>1)a[2:i-1],z(a[i],2*(n-i)+1),if(i>1)a[i:2-1])}

这是我的第一次发布，有人告诉我我没有R的最近几年的经验，所以请在这里稍加练习。

return Y?a[s](0,N):a}

将字符串数组传递给函数f()，如下所示：

f(
`AAAAAAA
ABBBBBA
ABCCCBA
ABCDCBA
ABCCCBA
ABBBBBA
AAAAAAA`.split('\n'), 3)

高尔夫版本较少，带注释：

f=(a,N)=>{
    // Whether to truncate array horizontally to width N.
    X=0

    // Whether to truncate array vertically to height N.
    Y=0

    // If a second row exists...

        // If the first non-whitespace character in the second row == 'B', truncate vertically.
        if(I.trim()[0]=='B')Y=1
