Codewars is an educational community for computer programming. On the platform, software developers train on programming challenges known as kata . These discrete programming exercises train a range of skills in a variety of programming languages, and are completed within an online integrated development environment .
Mutual recursion. In mathematics and computer science, mutual recursion is a form of recursion where two mathematical or computational objects, such as functions or datatypes, are defined in terms of each other. [1] Mutual recursion is very common in functional programming and in some problem domains, such as recursive descent parsers, where ...
CodeCombat is an educational video game for learning software programming concepts and languages. This game is recommended for students ages 9–16. Students learn to type coding languages like JavaScript, Python, HTML and CoffeeScript, as well as learning the fundamentals of computer science. CodeCombat has 11 units - three game development ...
In computer science, a binary decision diagram (BDD) or branching program is a data structure that is used to represent a Boolean function. On a more abstract level, BDDs can be considered as a compressed representation of sets or relations. Unlike other compressed representations, operations are performed directly on the compressed ...
I/O is inherently impure: input operations undermine referential transparency, and output operations create side effects.Nevertheless, there is a sense in which a function can perform input or output and still be pure, if the sequence of operations on the relevant I/O devices is modeled explicitly as both an argument and a result, and I/O operations are taken to fail when the input sequence ...
In computer programming, a function (also procedure, method, subroutine, routine, or subprogram) is a callable unit[ 1 ] of software logic that has a well-defined interface and behavior and can be invoked multiple times. Callable units provide a powerful programming tool. [ 2 ] The primary purpose is to allow for the decomposition of a large ...
Khan Academy is an American non-profit [3] educational organization created in 2006 by Sal Khan. [1] Its goal is to create a set of online tools that help educate students. [4] The organization produces short video lessons. [5] Its website also includes supplementary practice exercises and materials for educators.
C mathematical functions. C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. [1][2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions.
