search(+Tree, ++Key, ?Value)
Search a tree for a key.
- A 2-3-4 tree
- A key to search for
- The value corresponding to Key
This predicate searches the tree Tree for an entry with key Key.
If the key is found, then it attempts to unify the corresponding
value with Value.
This predicate should only be called with trees created by other
predicates from the tree234 module.
Fails if Key does not appear in Tree or if Value does not unify with the corresponding value found.
