If you don't care how you get the results, then this works (if I read your problem statement correctly). It uses List::Compare from CPAN.
#!usr/bin/perl use strict; use warnings; use feature 'say'; use Data::Dumper::Simple; use List::Compare; my @dead_list = (100, 101, 103, 200, 201, 202, 203, 210, 211, 212, 220, 221, 222, 230, 231, 232, 233, 240, 241, 242, 243, 1000, 1001, 1002, 1010, 1011, 1012, 1020, 1021, 1022, 1120, 1121, 1122, 1210, 1211, 1212); my @get_list = ( '100', '200', '210', '220', '230', '240', '1000', '1001', '1002', '1120', '1210',); my $lc = List::Compare->new(\@dead_list, \@get_list); my @result = $lc->get_unique; say Dumper(@result); __END__ @result = ( '101', '1010', '1011', '1012', '1020', '1021', '1022', '103', '1121', '1122', '1211', '1212', '201', '202', '203', '211', '212', '221', '222', '231', '232', '233', '241', '242', '243' );

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
