- RECURSIVE PYTHON The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: fibonacci(7) is 13 Note: Use recursion and DO NOT use any loops. # TODO: Write recursive fibonacci() functiondef fibonacci(): if __name__ == "__main__": start_num = int(input()) print('fibonacci({}) is {}'.format(start_num, fibonacci(start_num)))JAVA LANGUAGE The first examples of recursion are the mathematical functions factorial and fibonacci. These functions are defined for non-negative integers using the following recursive formulas:factorial(0) = 1factorial(N) = N*factorial(N-1) for N > 0fibonacci(0) = 1fibonacci(1) = 1fibonacci(N) = fibonacci(N-1) + fibonacci(N-2) for N > 1Write recursive functions to compute factorial(N) and fibonacci(N) for a given non-negative integer N, and write a main() routine to test your functions.(In fact, factorial and fibonacci are really not very good examples of recursion, since the most natural way to compute them is to use simple for loops. Furthermore, fibonacci is a particularly bad example, since the natural recursive approach to computing this function is extremely inefficient.) JAVA LANGUAGEIn order to accomplish the task of terminating recursion, you must first describe three distinct types of recursion, a high-level description of each kind, and a specific technique that fits into each category.

(b) Draw a call-stack…Artificial Intelligence (Part - 2) ==================== The Towers of Hanoi is a famous problem for studying recursion incomputer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. (2) What is the size of the state space?using recursion python Consider the English alphabet consisting of 26 lowercase letters: a, b, c, · · ·, x, y, z. • To this order, letters appear earlier are defined smaller. For example, the letter a is smaller than the letter b, and z is the largest letter since it appears last in the alphabet. • The least letter of an English word is the smallest letter that appears in that word. For example, the least letter of “Saturday” is “a”, and the least letter of “hello” is “e”. You are asked to write a program consisting of a function and a main interface as follows. (a) function recur_least_letters(l): Goal: collects all the least letters of words in list l (one least letter for each word) and returns the string of the obtained least letters in the order that the corresponding words appear in list l. • Input: a list l of English words • Output: string of all the least letters of words appearing in list l • Example: input: l = [‘today’, ‘is’, ‘saturday’] → output: “aia” Recursion is…
