Okay, here's my take.
- my board is some kind of a 2D array.
- 'x' are 1.
- 'o' are -1.
- empty is 0.
we look for an absolute 3. But I'm sure there is a more mathematical way for this:
my @board;
while (<DATA>) {
chomp;
push @board, [split / /];
}
for my $i (0 .. 2) {
my ($t1, $t2, $t3, $t4) = (0,0,0,0);
for my $j ( 0 .. 2 ) {
$t1 += $board[$i][$j];
$t2 += $board[$j][$i];
$t3 += $board[$j][$j];
$t4 += $board[2 - $j][$j];
}
if (abs($t1) == 3 || abs($t2) == 3
|| abs($t3) == 3 || abs($t4) == 3) {
print "Win.\n";
last;
}
}
__DATA__
1 0 1
-1 1 -1
1 0 1
He who asks will be a fool for five minutes, but he who doesn't ask will
remain a fool for life.

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).
