👉 A recurvant is a type of recurrence in computer science and programming. In computer science, it refers to a sequence or pattern that repeats repeatedly within a given function or algorithm. For example, consider the following function: ```python def fibonacci(n): if n <= 1: return n else: return fibonacci(n-1) + fibonacci(n-2) ``` This function computes the nth Fibonacci number using a recursive approach. The function has two parameters: `n
