Perl code to reverse the string

use POSIX; # for using floor function

chomp($str= <STDIN>);
@string = split ('',$str); # splitter will come first

$len=@string; # length of array

print "Array Length = $len ";

$n=floor((@string)/2);

for($i = 0 ; $i < $n ; $i++) # necessary to use $ with all variable
{
$temp=$string[$i];
$string[$i]=$string[$len-$i-1];
$string[$len-$i-1]=$temp;
}

$string = join ('',@string);
print "reversed string is :- ".$string ."\n";
