The “odd/even factorial” of a positive integer n is represented as n!! and is defined recursively as: a. (n)*(n-2)*(n-4)………*(2) if n is even. For example, 6!! = 6*4*2 = 48 b. (n)*(n-2)*(n-4)*…….*(5)*(3)*(1) if n is odd. For example, 7!! = 7*5*3*1 = 105. Come up with a recursive definition for n!! and use it to guide you to write a method definition for a method called “oddevenfact” that recursively calculates the odd/even factorial value of its single int parameter. The value returned by “oddevenfact” is a long.

The “odd/even factorial” of a positive integer n is represented as n!! and is defined recursively as: a. (n)(n-2)(n-4)………(2) if n is even. For example, 6!! = 642 = 48 b. (n)(n-2)(n-4)…….(5)(3)(1) if n is odd. For example, 7!! = 7531 = 105. Come up with a recursive definition for n!! and use it to guide you to write a method definition for a method called “oddevenfact” that recursively calculates the odd/even factorial value of its single int parameter.

Complete the following recursive method for computing the factorial of an integer. Assume that n is greater than or equal to 0. a. result = n * factorial(n - 1)b. result = n * factorial(n)c. result = factorial(n - 1)d. result = (n - 1) * factorial(n)e. result = (n - 1) * factorial(n - 1)
PHP A factorial of any given integer, n , is the product of all positive integers between 1 and n inclusive. So the factorial of 4 is 1 × 2 × 3 × 4 = 24, and the factorial of 5 is 1 × 2 × 3 × 4 × 5 = 120. This can be expressed recursively as follows: ❑ If n == 0, return 1. (This is the base case) ❑ If n > 0, multiply numbers from n down to 1. Write a PHP function to display the factorials of the integers up to the given value(argument). Any format could be used for displaying. Write the recursive version of the same function to display the factorials of the integers up to the given value(argument). Any format could be used for displaying.

Factorial of a number is defined as: n! = n(n-1)(n-2)(n-3)...(2)(1) For example, 4! = 4*3*2*1 The n! can be written in terms of (n-1)! as: n! = n* (n-1)! (n-1)! = (n-1)*(n-2) ! and so forth. Thus, in order to compute n!, we need (n-1)!, to have (n-1)!, we need (n-2)! and so forth. As you may immediately notice, the base case for factorial is 1 because 1! = 1. Write a program that uses a recursive function called factorial that takes an integer n as its argument and returns n! to the main. C++ PLEASE

Ackermann’s function is a recursive mathematical algorithm that can be used to test how well a computer performs recursion. Write a function A(m, n) that solves Ackermann’s function. Use the following logic in your function: If m = 0 then return n + 1 If n = 0 then return A(m-1, 1) Otherwise, return A(m-1, A(m, n-1)) Test your function in a driver program that displays the following values:A(0, 0) A(0, 1) A(1, 1) A(1, 2) A(1, 3) A(2, 2) A(3, 2)

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.)
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)))
