I recently found out about the Rose tree data structure, but just going off of a Haskell
data definition and the tiny Wikipedia description of it, I've got some trouble understanding what applications a Rose tree might have.
For reference, the Haskell
data RoseTree a = RoseTree a [RoseTree a]
For those unfamiliar with Haskell -- it's a recursive data type definition with an arbitrary type
a, where the type constructor is provided with a literal of type
a followed by an optionally empty list of type
RoseTree on the same type
The way I see it:
This data structure is unordered by default (although I assume most practical applications do implement some form of ordering for searching)
The data structure doesn't enforce a fixed number of nodes per layer at any point, except the global root, which must have a single node
Given that minimal amount of information, I'm having trouble figuring out when one might use this type of tree.
In addition to the question in the title, if search is indeed implemented in most applications of a Rose tree, how is this done?
