Count Binary Search Trees created from N unique elements

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 elements. This article addresses...

Building Binary Search Trees – detailed discussion

Introduction This is the second 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 will resume from where we concluded in the first article, this is primarily to understand how to build a BST and understand the problems which arise after building Binary Search Trees. Then we will improve over it and find out ways to build better BSTs. Do remember there is a...

Operations on a binary tree – Hierarchical Datastructure

Introduction This is the eighth article in the series of non-linear data structures, to read more about the previous article, please check the topic Binary Tree – Print all paths in a tree. To get updates on the coming articles in the series, please use the Subscribe feature on the right panel. Purpose of article This article is mostly about operations on a binary tree, writing code to delete a binary tree, mirror a binary tree, finding the height of a node and finding the depth of a node. We will use the same tree which we have used till now for all these operations. The tree is shown belo...

Binary Tree – Print all paths in a tree

Introduction This is the seventh article in the series of non-linear data structures, to read more about the previous article, please check the topic Hierarchical Datastructure – Tree Traversals. To get updates on the coming articles in the series, please use the Subscribe feature on the right panel. Purpose of article This article is mostly about using our knowledge of tree to find out ways to solve real world problems and also perform some operations on the tree. We visit the problem to Print all paths in a tree. Common Operations on a Tree Here we assume that we already have a tree bui...

Dynamic Programming – Longest Common Subsequence

[nextpage title="Introduction"] This is the first post in Dynamic Programming - Online Classes. Dynamic programming have been a very interesting topic and technique to solve problems which exhibit a specific set of behaviors. We will try to understand the behaviors and the way it can be implemented to solve complex problem without requiring a mathematical approach. We will try to simplify it to make it clearly understandable and in later articles we will pick up two or three problem statements which can be easily solved using Dynamic Programming. Purpose of the article The purpose of thi...

Hierarchical Datastructure – Iterative Tree Traversals

[nextpage title="Introduction"] This is the second article in the Tree Traversals - Online Classes. This is the sixth article in the series of non-linear data structures, to read more about the previous article, please check the topic Hierarchical Datastructure – Tree Traversals. To get updates on the coming articles in the series, please use the Subscribe feature on the right panel. Purpose of article We are already done with the constructing a binary tree and doing basic operations like creating a tree, adding a node, removing a node and all the traversals. There are situations when we...
