- Write a C++ recursive function int fib(int n) that returns the value of the n’th Fibonaccinumber . Do not use a loop. Test it in the main program, not in the function.The Fibonacci sequence is0 1 1 2 3 5 8 13 21…Each Fibonacci number is the sum of the preceding two Fibonacci numbers.arrow_forwardPlease written by computer source solve the question in pythonarrow_forwardWrite a program called p3.py that contains a function called reveal_recursive() that takes a word (string) and the length of the word (int) as input and has the following functionality: 1. prints the word where all characters are replaced by underscores 2. continue to print the word revealing one character at a time. i.e., the second line printed should print the first character followed by “_”’s representing the rest of the word. (see example below) 3. the function should end after printing the entire word once. 4. This function should be recursive Example: #the word is kangaroo ________ k_______ ka______ kan_____ kang____ kanga___ kangar__ kangaro_ kangarooarrow_forward
- 1) Write a recursive void function that has one parameter that is a positive integer and that writes out that number of asterisks (*) to the screen, all on one line. How do I do this in python?arrow_forwardNeed some help with this c++ problem In order to compute a power of two, you can take the next-lower power and double it. For example, if you want to compute 211 and you know that 210 = 1024, then 211 = 2 × 1024 = 2048. Based on this observation, write a recursive function int pow2(int n) where n is the exponent. If the exponent is negative, return -1. int pow2(int n) { ..... }arrow_forwardWrite a C++ program to read in 10 prices (function getprices). Then write function caldiscount to do a 10% discount of all the prices in the array. Next write calaverage to calculate the average. And finally write printarray to print all the prices in the array it's urgent give me proper codearrow_forward
- Write a function called Divisors which takes an integer and print all its divisors on the screen. Write the main program to call Divisors function, with an integer x t be taken from the user. Example: if x = 20, then the divisors are: 1, 2, 4, 5, 10, 20.arrow_forwardPlease answer in c++arrow_forwardWrite a c++ program that asks the user to enter an integer number and then by a recursive function find the addition of all integer numbers from 0 to the number user entered. N.B: Please,use a recursive function.arrow_forward
- Use pythonarrow_forwardHi can check my code below and see whether it has meet the following, if not kindly assist and correct it for me. a). Recursive function in Java that accepts an integer as input and returns 1 + 1/2 + 3 + 1/4 + ...(n or 1/n). b). The answer is the sum of the odd integers from 1 to n plus the sum of the reciprocals of the even integers. Thank you. public class Main {public static double sum(int n) {if (n <= 0) {return 0;} else if (n % 2 == 0) {return 1.0 / n + sum(n - 1);} else {return n + sum(n - 1);}}public static void main(String[] args) {System.out.println(sum(5));}}arrow_forwardObjective: Practice writing recursive functions in python3 Make the five recursive functions described below in python3 by using the starter code recursive_functions.py. For each function, figure out how to solve it conceptually : write down the base case (when recursion stops) and how each recursive function-call moves towards the base case. The functions should not print anything (except you may add temporary print statements to help debug them). You can test your program by using the provided program test_recursive_functions.py. Don't edit the test program. Put it into the same directory (folder) with your recursive_functions.py and run it. It will import your functions as a module, test your functions, and tell you when each function is returning correct results. 1. Factorial In math, if you have a number n, the factorial function (written n!) computes n x (n-1) x (n-2) x (n-3) x ... x 1. For example: 0! is defined to be 1 1! = 1 2! = 2 x 1=2 3! = 3 x 2 x 1=6 4! = 4 x 3…arrow_forward
