You can build a real linked list, you donīt even need objects:
use strict; use warnings; #build a cyclic list of hashes my $root = {value => 0, next => undef}; my $last = $root; for (my $i=1; $i<5; $i++) { my $node = { value=>$i, next => undef}; $last->{next} = $node; $last = $node; } $last->{next} = $root; #cycle: my $node = $root; for ( my $j=0; $j<10; $j++ ) { print $node->{value}, "\n"; $node = $node->{next}; }
Update:
The basic algorithms are the same than in any other language. The most important here is an understanding of how references work (see perlre), so i leave the rest as excercise for the interested reader.
