Preface. The overall cost of searching a node should be less. 1 What is a binary search tree? 12. Binary search tree (BST) is a sorted binary tree, where key stored in each node must satisfy the binary search tree property: 1) Keys in the left subtree ≤ Node key 2) Keys in the right subtree ≥ Node key 3) Both subtrees must be binary search trees. Optimal BSTs are generally divided into two types: static and dynamic. CLO 4. 1 Searching Tango trees To search this data structure for node x, we start at the root node of the topmost auxiliary tree (which contains the root of P). 8 Advanced Trees 2.
