Uses BSTs are used for sorting and searching. How They Work Search To find value v in tree t , If t is empty, return failure. If v is at the root, return success. WebTo implement a binary search tree, we will use two classes: one for the individual tree nodes, and one for the BST itself. The following class definitions assume that the BST will store only key values, no associated data. Because most of the BST operations require comparing key values, the type used for the key is Comparable(not Object). cryptex club
