Can you comment on this by which logic the first for conditions are set ( 0 .. $#lt -1 ) also the combination $# I have not encountered something like this what does it mean?
Absolutely. That's what this place is all about.
[
[1],
[2, 3],
[4, 5, 6],
[7, 8, 9, 10]
]
### $#array is the highest index in @array.
my $yMax = $#lt;
## $#{ ... } is the highest index in the array referenced by ...
## $array[ -1 ] is the last element in the @array
## So the following sets $xMax to highest index of the array (referenc
+e)
## in the last element of @lt. Ie. The longest subarray.
my $xMax = $#{ $lt[-1] };
## Iterate through each the subarrays except the last which does need
+padding
for my $y ( 0 .. $yMax -1 ) {
## for $lt[ $y=0 ] ([1]), we need to add elements $y+1..$xMax (
+1..3)
## for $lt[ $y=1 ] ([2,3]), we need to add elements $y+1..$yMax (
+2..3)
## And the value we add at $lt[ $y ][ $x ] comes from $lt[ $x ][ $
+y ].
for my $x ( $y+1 .. $xMax )
push @{ $lt[ $y ] }, $lt[ $x ][ $y ];
}
}

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).
