This is to determine the pairs only

That should take seconds, not minutes.

#!/usr/bin/perl use strict; my $t0 = time; my @f = map{ sprintf 'product_%04d',$_ } 1..2083; my $count = 0; open OUT,'>','pairs.txt' or die "$!"; while (my $x = shift @f){ for my $y (@f){ ++$count; print OUT "$count\t$x\t$y\n"; } } close OUT; my $dur = time-$t0; print "$count in $dur s\n"; # 19s on raspberryPI

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