Getting Started with Git

    Introduction to Git

    In professional development environments, the code is written in teams of developers. From your colleague sitting around the corner to a remote developer living across the globe, anyone could be writing code with you and contributing to the same codebase. The best and most popular way to contribute code to a single codebase is Version Control Systems.

    Version Control Systems

    Version control systems are systems that allow us to contribute to and manage different releases and stages of a software product without actually having to keep multiple files or folders. They also make development within a team more manageable and less of a pain as developers don’t have to be trading folders, but rather communicate with a single source where all the changes are happening and everything is saved.

    blockchain Programming

    Blockchain Overview

    Traditionally, there have been middlemen who have been controlling the data. For instance, Facebook is the middleman between users and advertisers. Banks are middlemen between borrowers and lenders. The issue here is that the data is controlled by a central authority – Facebook and banks. They, therefore, control the prices and also technically own the data. In this scenario, all the power lies with a middleman and users have to trust them to remain ethical and continue to think about user interest. Blockchain was invented to make the data decentralized and trust minimized with any centralized party.

    Merge Sort in C

    Merge sort is one of the most powerful sorting algorithms. Merge sort is widely used in various applications as well. The best part about these algorithms is that they are able to sort a given data in O(nLogn) complexity as against O(n2) complexity (we will soon see how) of bubble sort and selection sort. Moreover, merge sort is of interest because it creates an excellent case study for one of the widely used techniques in Computer Science – divide and conquer.
