Binary search is an efficient data structure in which we can store data to get search, insertion and deletion, all in O(log n Recent Articles on Binary Search Tree ! Binary Search Tree is a node-based binary tree data structure which has the following properties: The left subtree of a node contains only nodes with keys lesser than the node’s key.  A separate class is developed for each because each uses a different search.  The technique of balancing the height of binary trees was developed by Adelson, Velskii, and Landi and hence given the short form as AVL tree or Balanced Binary Tree.  In that case, it&#39;s possible to improve upon the bounds given by balanced BSTs.  In one case, the binary search tree, no additional information is required.  Linear, linked, and orthogonal lists; tree structures.  Chapter 12 is new to this edition.  Then, by using an SBB(k)-tree with a varyingk we achieve a structure with a logarithmic amortized cost per update and a height of logn+o(logn).  Data Structures and Algorithm Analysis Edition 3.
