Hello people…! In this post we will discuss one of the most commonly used search algorithm, the Binary Search. In a search algorithm, we are given an element and a collection or a set of elements. If the given element exists in the given set, we must return where it is located, or otherwise, if it does […]
Hello people..! In this post, we will look at a simple dynamic programming based algorithm which is the optimal solution to the Maximum Sum Subarray Problem. Try to focus on how the approach of dynamic programming is applied rather than just trying to understand the main algorithm. Now, let us define the problem. Maximum Sum […]
Hello, people..! In this post, we will explore some more aspects of object-oriented programming, which is overloading methods, but before that, I thought it is the right the time to tell you about what a constructor is. Constructor The constructor is a special method which is written in a class. This is called exactly once […]
Hello, people..! Now we are going to look at the most basic and the first major topic in Object Oriented Programming, Encapsulation. For those who don’t know OOP, it is very important that you spend a lot of time trying to understand these concepts. Because once you learn these concepts, it will be exactly the […]
Hello people..! In this post we will talk about solving another competitive programming question based on trie tree. I will take up the SPOJ problem – DICT. This is a little harder than the previous trie tree practise problem, PHONELST. Now, read the problem statement carefully a couple of times. Just so that you don’t […]
Hello people..! In this post I will show you how to get started with solving Trie Tree based questions in competitive programming. Learning a data structure is different from solving competitive coding questions based on that data structure. In this post, I take up a very simple question so that your confidence is boosted. We […]
Hello people..! So we finally come to the most famous part of Java, the Object Oriented Programming (OOP). Although I introduce OOP in this post, this post mainly to get you started with the notion of classes and objects. But, before we start our discussion on OOP, let us see why the modern world is […]
Hello people..! This is a new post in Java Tutorials – Enum and Methods in Java. In this post I will talk about enum and methods (that is, functions) in Java. The full potential and usage of these constructs will be seen when we start creating classes. But you’ve gotta start somewhere..! So this post […]
Hello people..! This is a new post in Java Tutorials – Arrays in Java. In this post I will talk about about using arrays in Java. Arrays in Java are different from arrays in C. Arrays in Java are actually objects. But understanding arrays as being-an-object point-of-view is not something beginners feel comfortable with. So […]
Hello people…! This is a new post in Java Tutorials – String, StringBuffer and StringBuilder in Java. In this post, I will talk about some basics about Strings in Java. Why basics…? Well, there is a lot in Java when it comes to Strings, which we can’t understand right now due to lack of knowledge. […]
