WebApr 6, 2024 · The Recursive Function has 2 parts: The value of the smallest or the first term in the sequence, usually given as f (0) or f (1) The pattern or the rule which can be used to get the value of any term, given the value of the term preceding it. In other words, the definition of f (n) when values of f (n-1), f (n-2), etc are given.

WebIn programming terms, recursion is a function calling itself until a "base condition" is true to produce the correct output. In other words, to solve a problem, we solve a problem that is a smaller instance of the same problem, and then use the solution to that smaller instance to solve the original problem.
