How to initialize an array? I want to get a median by using
Statistics::Descriptive.
I enter (12, 13, 14), (15, 16, 17), (16, 17, 18)
I expect 13,16,17. Instead,
I get 13.00, 14.50, 16.00.
I thought my @temp_array=(); in the median sub (see code snippet below) will
get me new array. But I am wrong. How do I initialize an array in my example?
Thanks for helps.

#### code snippet #####
use Statistics::Descriptive;
my $stat = Statistics::Descriptive::Full->new();
use strict;
use warnings;
my $i;
sub median {
my $count = $_[0];
my @temp_array=();
print "\nthe number of item in array: ", $stat->count();
for ($i=0; $i<$count; $i++) {
print "\nenter a number: "; my $temp_C=<STDIN>;
push @temp_array, $temp_C
}
$stat->add_data(@temp_array);
my $median = $stat->median();
my $num = $stat->count();
print "\nmedian: $median of $num items";
return $median;
}
my $T0 = sprintf "%.2f", median(3);
my $T1 = sprintf "%.2f", median(3);
my $T2 = sprintf "%.2f", median(3);
print "\n$T0\t$T1\t$T2";
#### output ##########
the number of item in array: 0
enter a number: 12
enter a number: 13
enter a number: 14
median: 13
of 3 items
the number of item in array: 3
enter a number: 15
enter a number: 16
enter a number: 17
median: 14.5 of 6 items
the number of item in array: 6
enter a number: 16
enter a number: 17
enter a number: 18
median: 16
of 9 items
13.00 14.50 16.00
