Introduction
This article is to highlight the importance of having a Search tree with minimum height and revisit couple of data structures which can guarantee a minimum height Tree.
Understanding Search Trees - Red Black Trees
An evolution of BST that aim to keep the tree balanced without affecting the complexity of the primitive operations. This is done by colouring each node in the tree with either red or black and preserving a set of properties that guarantees that the deepest path in the tree is not longer than twice the shortest one.
A red black tree is a binary search tree with the...

## Data Structures and Algorithms – Recursion

Introduction
The article Data Structures and Algorithms – Recursion is the third in series, of online course for Data Structure Algorithm. This is an effort to introduce and explain the Recursion methodology of algorithm design and programming. We will try to write some recursion based code and analyze the complexity of the algorithms in detail.
Recursion
It is the concept of defining a method that makes a call to itself and the call is termed as a recursive call. This is a readable and still efficient way of designing algorithms in the scenario where the problem in hand can be redefined by...

## Asymptotic Analysis

[nextpage title="Introduction"]
This article Data Structures and Algorithms – Asymptotic Analysis presents a better approach to understand how to analyze algorithms. Moreover, we would like to understand what algorithms are and why they are important. In this article we will just try and understand the idea behind analyzing algorithms.

## Data Structures and Algorithms – Introduction

Introduction
This series of articles is from the online sessions I conduct for working professionals as a part of the data structures and algorithm subject. I will keep posting each session's article here so that it can be used by everyone who is not able to attend the sessions.

What are data structures?
Data is the basis of information, in today’s e-age information is the most important asset. An important and un-deniable fact about data is that its volume is exponent...

[nextpage title="Introduction"]
This is the third article for Binary Search Trees, to read more about the previous article, please check the topic Binary Search Tree Basics – a detailed discussion. To get updates on the coming articles in the series, please use the Subscribe feature on the right panel.
Purpose of article
This article explains few more aspects of binary search tree (BST). In the last article we learnt to construct a BST and then we revisited our technique to construct a better BST with the same. So this means that there can be more than one BST possible with a given set of e...
