adding "save" array, and "if" to "unless"...

perl -wMstrict -e '
my @colors = qw(red green blue yellow pink purple brown);
my @drop = qw(pink purple);
my @save = ();
while ( my ($num, $val) = each @colors ) {
  unless ($val eq $drop[0] or $val eq $drop[1]) {
    push @save, $colors[$num];
  }
}
print "@save \n";
'
__output__
red green blue yellow brown
