Algorithms + Data Structures = Programs [1] is a 1976 book written by Niklaus Wirth covering some of the fundamental topics of system engineering, computer programming, particularly that algorithms and data structures are inherently related. For example, if one has a sorted list one will use a search algorithm optimal for sorted lists.
Fast inverse square root — calculates 1 / √ x using details of the IEEE floating-point system; Elementary functions (exponential, logarithm, trigonometric functions): Trigonometric tables — different methods for generating them; CORDIC — shift-and-add algorithm using a table of arc tangents
Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

Software engineering – The principles and practice of designing, developing, and testing programs, as well as proper engineering practices. Algorithm design – Using ideas from algorithm theory to creatively design solutions to real tasks. Computer programming – The practice of using a programming language to implement algorithms.
Symbolic programming is a paradigm that describes programs able to manipulate formulas and program components as data. [4] Programs can thus effectively modify themselves, and appear to "learn", making them suited for applications such as artificial intelligence , expert systems , natural-language processing and computer games.
Examples of distributed systems vary from SOA-based systems to massively multiplayer online games to peer-to-peer applications, and blockchain networks like Bitcoin. A computer program that runs in a distributed system is called a distributed program, and distributed programming is the process of writing such programs. [16]
The details look different in different languages, but a few basic instructions appear in just about every language: Input: Gather data from the keyboard, a file, or some other device. Output: Display data on the screen or send data to a file or other device. Arithmetic: Perform basic arithmetical operations like addition and multiplication.
The NIST Dictionary of Algorithms and Data Structures [1] is a reference work maintained by the U.S. National Institute of Standards and Technology. It defines a large number of terms relating to algorithms and data structures. For algorithms and data structures not necessarily mentioned here, see list of algorithms and list of data structures.
