( #3333=superdoc: print w/replies, xml ) Need Help??
I slightly modified my script:
#!/usr/bin/perl use feature 'say'; use warnings; use strict; my $file = 'words.txt'; open my $IN, '<', $file or die "$!"; my %words; while (my $word = <$IN>) { chomp $word; undef $words{$word}; } my %reported; for my $word (keys %words) { my $length = length $word; for my $pos (0 .. $length - 1) { my $skip_itself = ! $pos; for my $len (1 .. $length - $pos - $skip_itself) { my $subword = substr($word, $pos, $len); next if exists $reported{$subword}; next if $word eq $subword . q{s} or $word eq $subword . q{'s}; if (exists $words{$subword}) { say "$subword"; undef $reported{$subword}; } } } }
I used english.0 from this archive as words.txt: http://downloads.sourceforge.net/wordlist/ispell-enwl-3.1.20.zip. Your script took 58s, whilest mine only 6s (on Pentium 4, 2.8 GHz). The results were different, though: your output contains the word indistinguishableness that mine does not; my list contained 911 more words than yours (e.g. you, wraps or tribe's).

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



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
