( #3333=superdoc: print w/replies, xml ) Need Help??

hello, again

I noticed $hash arg not passed to functions. You don't see outputs of print statement, do you? Would you try this?

#!/usr/bin/perl use strict; use warnings; use Benchmark qw(:all); my %h; @h{'A'..'Z','a'..'z'} = 1..52; sub verbose { #my $hash = shift; foreach my $key (sort keys %h) { print "$key: $h{$key}\n"; } } sub idiom { #my $hash = shift; print map "$_: $h{$_}\n", sort keys %h; } my %tests = ( '01_verbose' => \&verbose, '02_idiom' => \&idiom, ); cmpthese( -10, #for 10 cpu secs \%tests ); __DATA__ Rate 02_idiom 01_verbose 02_idiom 5341/s -- -4% 01_verbose 5577/s 4% --
Personally, I like map.

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 How to display code and escape characters are good places to start.
