I am getting unexpected output after running the below code. Not sure why while loop is not working here in. 
#!/usr/bin/perl

print"Enter the key\n";

my $key = <STDIN>;

chomp($key);

print"Enter the value for the Key $key\n";
  
my $value = <STDIN>;
      
chomp($value); 

my %h = ();

while (($key ne "") && ($value ne ""))
{
             
    $h{$key} = $value;
        
    print "Value inserted successfully\n";
  
    print"Enter the key\n";

    my $key = <STDIN>;

#    chomp($key);
 
        print"Enter the value for the Key $key\n";
  
    my $value = <STDIN>;
      
#    chomp($value); 

}


foreach my $keyy (keys %h)
{

print "$keyy => $h{$keyy}\n";

}

The loop is taking the values for key and value pair from standard input but, its not exiting if a null value is given to it.
