## Dynamic Programming – Distinct Paths between two points

Introduction This is the second post in Dynamic Programming - Online Classes. This is another article which demonstrates the usage of dynamic programming to solve a different problem in hand. To learn the basics of dynamic programming check my first article on dynamic programming. Purpose of the article The purpose of this article is to solve another problem using dynamic programming, this is another very famous interview question which is asked in multiple interviews. So without wasting any time, let us jump into the problem and ways to solve the same. Count the number of distinct path...

## 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...
