Problem Solving and Algorithms Introduction A problem space is all of the various components that go into creating a resolution for a problem. Think of it like a frame, which acts as something of a border to help define an area. A problem space helps you or, on a larger scale, a business, figure out what the problem is, work through ways to correct them and then drives implementation of the appropriate solution. The ultimate purpose is to take corrective action for some identified problem. Problem solving refers to cognitive processing directed at achieving a goal when the problem solver does not initially know a solution method. In computer science there are two different types of problems, ill-defined and well-defined : different approaches are used for each. Well-defined problems have specific end goals and clear expected solutions, while ill-defined problems do not. In computer science, an algorithm is a finite sequence of well-defined , computer-implementable inst...

A Beginner's Guide to System Design Introduction Systems design is the process of defining the architecture, modules, interfaces, and data for a system to satisfy specified requirements. Systems design could be seen as the application of systems theory to product development. There is some overlap with the disciplines of systems analysis, systems architecture and systems engineering. Whether you are a backend developer, product manager or technical manager, everyone needs to know the basics of System Design. So this article is the only destination that can solve all queries you have about System Design. Aspects of System Design High Level System Design High-level design ( HLD ) explains the architecture that would be used for developing a software product. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces. The HLD uses possibly nontechnical to mildly te...

An Introduction to Version Control Systems(VCS) Introduction Version control systems are a category of software tools that help a software team manage changes to source code over time. Version control software keeps track of every modification to the code in a special kind of database. If a mistake is made, developers can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.Changes are usually identified by a number or letter code, termed the "revision number", "revision level", or simply "revision". For example, an initial set of files is "revision 1". When the first change is made, the resulting set is "revision 2", and so on. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and with some types of files, merged. [*]Source Code is a repository of the invaluable knowledge and unde...

A Basic Overview of LINUX Introduction Linux is a family of open source Unix-like operating systems based on the Linux kernel,an operating system kernel first released on September 17, 1991, by Linus Torvalds . Linux is typically packaged in a Linux distribution.Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project.Popular Linux distributions include Debian , Fedora , and Ubuntu . Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise Server . Desktop Linux distributions include a windowing system such as X11 or Wayland , and a desktop environment such as GNOME or KDE Plasma . Distributions intended for servers may omit graphics altogether, or include a solution stack such as LAMP . Because Linux is freely redistributed, anyone may create a distribution for any purpose.Linux was originally developed for personal computers based on the Intel x86 architecture, but has ...

5 Important Sorting Algorithm In computer science, a sorting algorithm is an algorithm that puts elements of a list in a certain order. The most frequently used orders are numerical order and lexicographical order. Efficient sorting is important for optimizing the efficiency of other algorithms (such as search and merge algorithms) that require input data to be in sorted lists. Here we will discuss 5 well known and important sorting techniques. Bubble Sort Insertion Sort Quick Sort Merge Sort Heap Sort 1. Bubble Sort Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort, is named for the way smaller or larger elements "bubble" to the top of the list. Although the algorithm is simple, it is too slow a...
