In this article, we will look into the different types of Recursion generally seen in programming to solve various problems. We will look at description of each type with example through code for better understanding. First of all, let’s have a quick recap of Recursion. In general, Recursion is an approach to solve problems where …
In this article, we will look at the difference between Binary Tree and Binary Search Tree. These topics are very important because these act as an underlying data structure for various other data structures. So, we will look at the description of each with examples and compare their properties. Binary Tree A Binary tree is …

In this article, we dive deep into the core concepts of multithreading. We will have a look at the profound understandings of the terms Concurrency and Parallelism with their description. Then, we compare the major differences between the two terms. Concurrency and Parallelism are often misunderstood to be somewhat similar but it is not the …

In this article, we will understand the idea of Kadane’s Algorithm. We discuss this with the help of an example and also discuss a famous interview problem related to it. Then, we will look at the implementation and analyze the complexities of our approach. Kadane’s Algorithm This algorithm is useful in solving the famous ‘Maximum …

In this article we have a look at another interesting problem related to binary tree. Given a binary tree we have to invert the tree and print it. We discuss different approaches to solve this problem along with their time and space complexities The inversion of a binary tree or the invert of a binary …

In this article we will learn how to design a LRU Cache, understand it’s cache replacement algorithm. We also look at description of LRU Cache with some examples. Then, we look at the implementation of this design in code with their complexity analysis. Caching is a method of organizing data in a faster memory, usually …
In this article we look into the difference between Primary Key and Unique Key Constraints. We will see the description of both along with how to define a schema and create attributes in a table with these constraints. Primary Key A Primary Key is a key attribute or a column which is used to uniquely …
In this article, we see how to print the bottom view of Binary Tree. We discuss our approach to solve this problem and analyze the time and space complexities. It is recommended to first learn Top View Of Binary Tree before proceeding with this problem. A lot of the implementation is based on the Top …
