Thanks for checking.

It fails if there were three or more zeroes (the test case provided has two zeroes), and if there are no zeroes.

Adding some extra checks seems to fix the issues, and is still close to try1a for speed given the provided test data (sometimes as fast but usually a few percent slower).

swl2 => sub { my @list = @input; use List::MoreUtils 0.428; @list = sort {$a<=>$b} @list; my $i = List::MoreUtils::bsearchidx {$_ <=> 0} @list; if ($i < 0) { # no zero $i = List::MoreUtils::firstidx {$_ >= 0} @list; } else { $i-- while !$list[$i]; $i++; } push @list, splice @list, 0, $i; Compare(\@list,\@output) or die "@list" if DO_CHECK; },

It will be slower in cases where there are no zeroes, although List::BinarySearch::binsearch_pos could be used to find an insert point for zero in such cases.

  • 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.
