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!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • Outside of code tags, you may need to use entities for some characters:
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
