Binary search trees are typically only efficient if they are balanced. There are two types of representation of a binary tree: 1. Each node should be prefaced by a series of < and > characters showing the path that leads from the root to that node. I've been trying to write a recursive string method for a binary search tree that returns a multiple line representation of a tree with preorder path info. Like any other dynamic data structure, BST requires storing of some additional auxiliary data, in order to keep its structure. As great as binary search trees are, there are a few caveats to keep in mind. Binary Tree (Array implementation) Talking about representation, trees can be represented in two way: 1) Dynamic Node Representation (Linked Representation). Binary Tree representation .

Potential Issues with Binary Search Trees. Internal representation. The binary search tree is a binary tree which holds ordered data. A bal­anced tree is a tree where the dif­fer­ence between the heights of sub-trees of any node in the tree is not greater than one. Binary Search Tree: Often we call it as BST, is a type of Binary tree which has a special property. Applications. Linked Representation. Operations: Nodes smaller than root goes to the left of the root and Nodes greater than root goes to the right of the root. Each node of binary tree contains the following information: a value (user's data); a link to the left child (auxiliary data); a link to the right child (auxiliary data). The ordering rule is as follows: the value in each node is greater than the value in its left child and less than the value in its right child. In this representation, the binary tree is stored in the memory, in the form of a linked list where the number of nodes are stored at non-contiguous memory locations and linked together by inheriting parent child relationship like a tree. 2) Array Representation (Sequential Representation). Left and right node of a Leaf node points to NULL so you will know that you have reached to the end of the tree. We are going to talk about the sequential representation of the trees. Binary search tree. The data in a BST is basically always kept sorted and this allows to quickly lookup existing elements.
