Hello,
I am looking for a way to print output to my screen in the reverse order that it sits in my array, BUT, without using the reverse command, like i do in my example.
Here is my code, at the moment, for printing output to the screen from a file:
<br>
<code>
my $input = 'somelist'; # Original Line
open(my $in, "<", $input) or die "Could not open $input because $!\n";
my @unsorted = <$in>;
chomp (@unsorted); # get rid of end-of-record markers
close ($in);
my @sorted = sort @unsorted;
for (my $i=0; $i <=$#sorted; $i++)
{
print $sorted [$i], "\n";
}
@rocks = reverse(@sorted);
foreach $rock (@rocks) {
$rock = "\t$rock" ; # \t is a tab
$rock .="\n" ;
}
print "\n";
print "The names, backwards, are:\n", @rocks;
</code>
I know I am close, but not sure how to context the issue.
It's in the formatting of the "for (my.." line, I think. Isn't it?
Any assistance / hints or pointers would be appreciated in this perplexing matter.
Thank you.
