Wasn't sure if this belongs here, or in Obfuscations.

Having once run:

use strict; use warnings; use Storable; my (%table); foreach my $i (0..9) { foreach my $j ($i..9) { $table{$i}{$j} = $table{$j}{$i} = $i + $j } } store \%table, 'addition_table';

I present to you: addition!

use strict; use warnings; use Storable; my %table = %{retrieve('addition_table')}; my @problem = @ARGV; my (%matrix); foreach my $number (@problem) { my $log = 0; push @{$matrix{$log++}}, $_ for reverse (split //, $number); } my $col = 0; while (exists $matrix{$col}) { my @column = @{$matrix{$col}}; my $first = shift @column; while(scalar @column > 0) { my $second = shift @column; $first = $table{$first}{$second}; if (length($first) > 1) { $first = substr($first,-1,1); push @{$matrix{$col + 1}}, 1; } } $matrix{$col++} = $first; } printf "%s",$matrix{$col - $_} for (1..$col); print "\n";

Addition tables for other number systems are left as an exercise for the (extremely bored) reader. Vaguely apropos of Multiply Hex values. I started to write a program to do multiplication and realized I needed to figure out how to add first.

But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Romans 5:8 (NASB)

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.
