creating a datastructure from lists
 

I need to convert the following lists:

house,doors,knobs,style
house,doors,knobs,color
house,windows,length
house,windows,width

into a datastructure like this;

$ds = {
'house' => {
'doors' => {
'knobs' => {
'style' => "",
'color' => '""
}
},
'windows' => {
'length' => "",
'width' => ""
}
}
};

Does this require the use of recursive calls? Thanks in advance.

No, it does not. You can create loop that iterates over every element
in the current line, each time assigning the reference you're using to
the most recently created level of the structure.

Once you've made an attempt, if it doesn't work the way you want, post
here again, including a SHORT but COMPLETE script that demonstrates
your error, and someone can probably help you to fix it.
