You could also use hashes for this: 

my %hash1 = ( 1  => '1',
              83 => '1',
              90 => '1',
             120 => '1',
             140 => '1',
             300 => '1'
            );

my @array = ('83', '140');

for (@array){
     delete $hash1{$_};
}

Now keys(%hash1) only contains the entries you want. you could do more checking or other processing in your loop if you wanted. You could even be 'safer' like this: 
for (@array){
     delete $hash1{$_} if exists $hash1{$_};
}

but it is a little silly since the delete will only do anything if the entry exists in the hash anyway.
