Re: Re: Re: Finding largest common subset in lists?

I'm stupid, stupid, stupid. There should be:

....
        if ($end > @result) {
            @result = @a[0..$end-1];
        }
...

instead of

...
        if (--$end > @result) {
            @result = @a[0..$end];
        }
...

The way I have it I'd only update the @result if the newly found list was longer by at least 2 items. The usual off-by-one error :-(
