Re^4: Words in Words

This process only needs to identify 1 word in the list that meets the criteria resulting in a unique list of the words that were contained within other words.

I suppose there would still be a problem if this process doesn't look at the words that preceed each word because something could be missed.

I have this code working and it sure is fast at producing a list of words. It just needs to return 1 word instead of all of the words that match and ensure that it searches the entire list.

Thank you!

This process only needs to identify 1 word in the list that meets the criteria resulting in a unique list of the words that were contained within other words.

Then add a single line to my solution above and it should reduce the time taken by roughly a factor of 10. Ie. A projected 1 hour:

#! perl -slw
use strict;

my @words = do{ local @ARGV = 'words.txt'; <> };
chomp @words;

my $all = join ' ', @words;

my $start = time;
my $n = 0;
for my $i ( @words ) {

    for my $j ( $all =~ m[ ([^ ]*$i[^ ]*) ]g ) {
        next
            if $j eq $i
            or $j eq "${i}s"
            or $j eq "${i}'s";
        print "$j contains $i";
        last;                     ## Added
    }
}

printf STDERR "Took %d seconds for %d words\n",
    time() - $start, scalar @words;
