If you start with a hash, just use keys and values to extract the first names and last names. To extract the names from a string, just add capture groups and /g to find all the matches:
#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };
my %names = qw (hanibal lecter Harry Potter INDIANA JONES Sarah connor scarlet O'Hara JAMES Bond);
say join ' ', 'First names:', keys %names;
say join ' ', 'Last names:', values %names;
my $scalar_string = "hanibal lecter Harry Potter INDIANA JONES Sarah connor scarlet O'Hara JAMES Bond";
my (@first_names, @last_names);
while ($scalar_string =~ /([w']+) ([w']+)/g) {
push @first_names, $1;
push @last_names, $2;
}
say join ' ', 'First names:', @first_names;
say join ' ', 'Last names:', @last_names;
