Fibonacci using recursive function in python

WebJul 18, 2024 · Python Fibonacci Series Using Recursion Here recursive function code is smaller and easy to understand. So using recursion, in this case, makes sense. What is the Base Case in Recursion? While defining a recursive function, there must be at least one base case for which we know the result. WebIn mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Individual numbers in the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) …

WebWhen the function is called with a value of n, it first checks if the result has already been computed and stored in the cache. If it has, the cached value is returned. Otherwise, the function computes the Fibonacci number using the recursive formula fibonacci(n-1) + fibonacci(n-2), stores the result in the cache, and returns the result.
