改写代码

#!/usr/bin/perl -w
use strict;

my$f= $[;my
$ch=0;sub l{length}
sub r{join"", reverse split
("",$_[$[])}sub ss{substr($_[0]
,$_[1],$_[2])}sub be{$_=$_[0];p
(ss($_,$f,1));$f+=l()/2;$f%=l
();$f++if$ch%2;$ch++}my$q=r
("\ntfgpfdfal,ce?bngbjn".
"axfvxf"); $_=$q; $q=~
tr/f[a-z]/ [l-za-k]
/;my@ever=1..&l
;my$mine=$q
;sub p{
print
@_;
}

be $mine for @ever

代码输出

复制代码 代码如下:ping, will you marry me?
