As an abstract data type, the abstract tree type T with values of some type E is defined, using the abstract forest type F (list of trees), by the functions:
value: T → E children: T → F nil: () → F node: E × … See more

Viewed as a whole, a tree data structure is an ordered tree, generally with values attached to each node. Concretely, it is (if required to be non-empty):
• A rooted tree with the "away from root" direction (… See more
