I'll leave the reading of the hash as an exercise to the user, but here's a fun way to populate the hash:

Update: Apparently, here's a really slow, dangerous, stupid, fraught with peril, performancing dehancing way to do it. Oh well, some code just sucks, don't it?
#!/usr/local/bin/perl -w use strict; use Data::Dumper; { my %hash = (); while (<DATA>) { my $s; $s .= "{'$_'}" foreach (/(...)/g); eval ('$hash ' . $s . '++'); die $@ if $@; } print Dumper ([\%hash]); } __DATA__ aaabbbcccddd aab aacbbb aaabbacca aaabbaccb ababbbddd

$VAR1 = [ { 'aab' => 1, 'aba' => { 'bbb' => { 'ddd' => 1 } }, 'aac' => { 'bbb' => 1 }, 'aaa' => { 'bba' => { 'cca' => 1, 'ccb' => 1 }, 'bbb' => { 'ccc' => { 'ddd' => 1 } } } } ];
