Introduction Sorting is one of the fundamental techniques used in solving problems, especially in those related to writing and implementing efficient algorithms. Usually, sorting is paired with searching - meaning we first sort elements in the given collection, then search for something within it, as it is generally easier to search for something in a…
Data can be stored in a file, which provides some form of a structure to the data and allows it to be stored permanently or temporarily depending upon the storage medium. Typically, main memory (or RAM) is used for temporary storage and hard disk, tape, and so on. are used for permanent storage. Programmatically handling…

Cloud infrastructure has pushed software towards abstracting the developer away from the operating hardware, making global networks and copious amounts of computing power available over API’s, and managing large swaths of lower tiers of the tech stack with autonomous software. Gone are the days of buying bulky servers to own and here are the times…
Embedded systems are the collection of the hardware and software where the software has been embedded into the hardware components. It is the electronic device that is programmed to perform a specific task. Now, these devices have become a crucial part of human life and help perform several multipurpose tasks. Therefore many people are showing…
Master declarative asynchronous programming with Swift using the Combine framework! Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work — delegates, notification center, KVO, closures, etc. Juggling all of these different mechanisms can be somewhat overwhelming. Does it really have to be this hard? Not…
