WebComputing the value of a Fibonacci number can be implemented using recursion. Given an input of index N, the recursive function has two base cases – when the index is zero or 1. The recursive function returns the sum of the index minus 1 and the index minus 2. The Big-O runtime of the Fibonacci function is O (2^N). WebMar 2, 2024 · Recursion: A Function calling itself again and again directly or indirectly is called Recursion, and the function which it calls is called a recursive function, it is used in divide and conquer algorithms/techniques.

WebEach recursive definition has two separate parts: a base case and a general (or recursive) case. 1. The easily solved situation is called the base case. The base case is a simple case of the problem that we can answer directly; the base case does NOT use recursion. Each recursive algorithm must have at least one base case.
