HI
sorry, I'm tired and it smells like homework...
So here only a stub for you to work on:
(Showing how to use a HoH to represent a table)
use strict;
use Data::Dumper;
my (%h,%x,%y);
scalar <DATA>;
while(<DATA>){
chomp;
my ($id, $size, $qty, $price)= split /\s*,\s*/,$_ ;
$h{$qty}{$size}=$price;
$y{$qty}=1;
$x{$size}=1;
}
for my $y (sort keys %y) {
for my $x (sort keys %x) {
if (exists $h{$y}{$x}) {
print "$h{$y}{$x}\t";
}else {
print "\t"
}
}
print "\n";
}
__DATA__
id, size, qty, price
1 , 1 , 100, 43
2 , 1 , 250, 52
4 , 2 , 100, 45
5 , 2 , 250, 55
6 , 3 , 100, 50
7 , 3 , 250, 56
8 , 4 , 200, 55
9 , 5 , 250, 61
OUTPUT:
43 45 50
55
52 55 56 61

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).
