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.
There are many factors that make a good framework, and you’ll find that many frameworks have been swapping places over the years. Thus, it’s not always easy to pick a framework to work with, especially if you’re just beginning with web development. Today, we’ll be exploring the Ruby on Rails framework, one of the most popular frameworks that people don’t seem to stop loving!
What is Rails?
Rails is an MVC web development framework that leverages the Ruby language and its perks to address productivity and development speed for developers. It’s one of the most used web frameworks, according to SimilarTech it’s powering over 2 million websites, including some of the biggest names like Airbnb, GitHub, and CodeAcademy. Rails is a versatile framework, it could be used as a complete server with powerful template rendering or it could be consumed as a RESTful API. It supports both options right out of the box. Rails also integrate well with frontend frameworks, especially React.
Introduction, Overview, and History
MongoDB is a powerful, highly scalable, free and open-source NoSQL based database. MongoDB was initially released approximately 9 years ago on 11th of February, 2009 and has since then achieved the position of the leading NoSQL database. The company MongoDB Inc. (New York, United States) maintains and manages the development of MongoDB. They also provide the commercial version of MongoDB which includes support also. The source code of MongoDB is available on Github.
Over the years, MongoDB has become a popular choice of a highly scalable database and it is currently being used as the backend data store of many well-known organizations like IBM, Twitter, Zendesk, Forbes, Facebook, Google, and a gazillion others. MongoDB has also caught the eyes of the open source community and a lot of developers work on various open source projects based on MongoDB. You can download MongoDB here: https://www.mongodb.com/download-center and find MongoDB documentation here: https://docs.mongodb.com/
Sorting of data is one of the most fundamental, yet an important problem in computer science. Sorting forms a great case study for those who want to learn Data Structures and Algorithms.
What is Sorting – Definition
Often in real life, we are supposed to arrange data in a particular order. For instance, during our school days, we are told to stand in the queue based on our heights. Another example is of the attendance register at school/college which contains our names arranged in the alphabetical order.
