( #3333=superdoc: print w/replies, xml ) Need Help??

This is anagramming, and the nicest solution is well-known here. Split your string into characters, sort them, and rejoin them. Compare against a hash with keys made the same way from your dictionary or wordlist.

my %dict = do { open my $fh, '<', '/usr/dict/words' or die $!; map {chomp; join( '', sort split //, lc $_), $_} <$fh>; }; my $canon = join '', sort split //, lc 'RTESAMCNA'; print $dict{$canon} if exists $dict{$canon};

No regex or combinatorial excess needed.

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.
  • 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
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
