Competitive programming or sport programming is a mind sport involving participants trying to program according to provided specifications. The contests are usually held over the Internet or a local network. Competitive programming is recognized and supported by several multinational software and Internet companies, such as Google [1][2], and Meta.
Codecademy was founded in August 2011 by Zach Sims and Ryan Bubinski. [6] Sims dropped out of Columbia University to focus on launching a venture, and Bubinski graduated from Columbia in 2011. [7] The company, headquartered in New York City, raised $2.5 million in Series A funding in October 2011 and $10 million in Series B funding in June 2012 ...
Dijkstra's algorithm (/ ˈdaɪkstrəz / DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later. [4][5][6] Dijkstra's algorithm finds the shortest path from a ...
Leet (or L33t) is an esoteric programming language based loosely on Brainfuck and named for the resemblance of its source code to the symbolic language "L33t 5p34k". L33t was designed by Stephen McGreal [1] and Alex Mole to be as confusing as possible. It is Turing-complete and has the possibility for self-modifying code.
CodeChef is an online educational and Programming Education platform. It began as an educational initiative in 2009 by Directi, an Indian software company. In 2020, it was purchased by Unacademy. After failing to reach profitability, Unacademy announced it would retain a 30% stake in CodeChef while returning the remaining equity to the company ...
In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.
Copy-on-write. Copy-on-write (COW), also called implicit sharing[1] or shadowing, [2], is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
