Hello,
I need help... I am having trouble with rose trees.
1
2 3 4
5 6 7 8 9 10 11
That is the rose tree that I seek.
Data Tree a = Empty | Leaf a | Node a [(Tree a)]
example :: Tree (String, String)
example = Node ("a","b") -- root node
[ ........................................] -- end of tree
What I want to do is create two functions that return either the children or
parents of a given input, here a String.
String -> Tree -> [String] I think
