Yes i know, this is terribly slow and so on. But i had some fun to play with it.

#!/usr/bin/env perl # $Id: 1196786.pl,v 1.3 2017/08/05 19:22:21 karl Exp karl $ # http://perlmonks.org/?node_id=1196786 use strict; use warnings; use Data::Dump qw(pp); use feature qw(say); my @points = ( [ 0, 0 ], [ -1, -2 ], [ 1, 2 ], [ -1, 2 ], [ 1, -2 ], [ 0, 1 ], [ 1, 0 ], [ -1, 0 ], [ 0, -1 ], [ 2147483647, 2147483647 ], [ 2147483647, -2147483647 ], [ -2147483647, 2147483647 ], [ -2147483647, -2147483647 ], ); kgb_str_look( kgb_str_hash() ); sub kgb_str_hash { my %cells = map { pp($_) => undef } @points; \%cells; } sub kgb_str_look { my $cells = shift; for (@points) { my $point = pp($_); ( exists $cells->{$point} ) ? say $point : die; } } __END__

Thanks for this interesting thread.

Best regards, Karl

Title:
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.
