Covariant Return Type in Java

Covariant return type in an Object oriented programming language means that the return type of any method can be replaced by a narrower type when it is overridden in the subclass or child class. We have explored it in Java in depth.

Simplified: C++ STL Lists

In this article, we have explored List in C++ STL in depth along with its member functions and applications. It is a good alternative to arrays.

Multiple Inheritance in Java (using Interface)

Java is an Object Oriented Programming language and supports the feature of inheritance. We cannot have Multiple Inheritance in Java directly due to Diamond Problem but it can be implemented using Interfaces.

Problems on Binary Tree

Implementing Binary tree in C++

In this article, we have explored how to implement Binary Tree Data Structure in C++ including all different operations like traversing, inserting and deleting. We have used Object Oriented Programming (OOP) concepts.

Override getattr in Python

Methods like __getattr__, is called when an atrribute is not found in the usual place(i.e. it is not an instance attribute nor is it found in the class tree for self).

Software Engineering

NamedTuples objects in Python

Using NamedTuples in Python helps you self-document your code conveying meaning to each field. Its methods allow you to work more easily with data.
