in reply to improving the efficiency of a script

My dictionary (/usr/share/dict/words) only has 96274 words :)

But anyway, here is my go at this - I'm not sure how efficient (or otherwise) it is - but it seems to work :)

Update 1: blah - I just realised that it doesn't work at all - the shuffle isn't doing anything. I'll update it again later when I get it working.

Update 2: - okay, working now :) (I think)

#!/usr/bin/perl -w use strict; use List::Util qw(shuffle); my $dict = '/usr/share/dict/words'; open DICT, "<", $dict or die "Cannot open $dict:$!\n"; my %words; WORD: while (my $word = <DICT>) { chomp $word; my ($letter) = $word =~ /^(\w)/; next WORD if !$letter; push @{$words{$letter}}, $word; } close DICT; foreach my $letter (sort keys %words) { @{$words{$letter}} = shuffle(@{$words{$letter}}); for my $number (1 .. 100) { print "$words{$letter}[$number]\n"; } }

Cheers,
Darren :)
