Rekursiver

Rekursiver is a term used in Scandinavian languages, notably Norwegian and Danish, to describe something that employs recursion. In these languages, rekursiv is the adjective for recursive, and rekursiver can appear in various grammatical forms to modify nouns or function as a label. In practice, Rekursiver may be encountered as a concept in textbooks, documentation, or as a name in software projects and educational resources emphasizing recursive techniques.

In computer science and mathematics, recursion refers to solving a problem by reducing it to smaller instances of the same problem. A recursive approach relies on a base case to stop the process and on one or more recursive calls to progressively approach that base case. Common examples include mathematical sequences defined by recurrence relations, factorial calculations, and tree or graph traversals such as depth-first search. Recursive definitions are often expressed through functions or procedures that call themselves with simpler inputs.

Advantages of recursion include clear and concise solutions for problems naturally described by smaller subproblems. Drawbacks can include higher memory usage due to call stacks and potential performance costs if not implemented with optimization techniques. Techniques such as tail recursion, memoization, and converting to iterative solutions are used to mitigate these issues.
