( #3333=superdoc: print w/replies, xml ) Need Help??
In regards to an old post about a caesar shift solution, I have tried my skills to approach this in an efficient way and came up with the following:
#!/usr/bin/perl -w # # Caesar shift decrypting script # Author: Aleksandr Melentiev <tzapper@users.sf.net> # Redistributable under the BSD License use strict; use warnings; print "Enter encrypted string:\n"; chomp(my $cipher = <STDIN>); my @alphabet = ('A' .. 'Z'); for (@alphabet) { my $text = $cipher; my $rot = join("", @alphabet); eval "\$text =~ tr/a-zA-Z/$rot/, 1" or die $@; print "ROT: $text\n"; push(@alphabet, shift(@alphabet)); }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
