- Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is:********************Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the above pattern.Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, the pattern generated is as follows: **** *** ** * * ** *** **** Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the preceding pattern.Write a recursive function called draw_triangle() that outputs lines of '*' to form a right side up isosceles triangle. Function draw_triangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Hint: The number of '*' increases by 2 for every line drawn. Ex: If the input of the program is: 3 the function draw_triangle() outputs: * *** Ex: If the input of the program is: 19 the function draw_triangle() outputs: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* Note: No space is output before the first '*' on the last line when the base length is 19. if __name__ == '__main__': base_length = int(input()) draw_triangle(base_length)
- Write a function which takes two integer parameters for values to be added together and returns the result by value. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Assume that the values passed to the function will not be negative, but could be 0 or positive, and will both be integers. The function must implement addition recursively, and cannot use the standalone + operator (only ++) or call any other functions.Given two integers x snf y, the following recurrsive definition determined the greatest common divisor of x and y, Write gcd(xy). Write a recursive function, gcd, that takes two integers as parameters and returns the greatest commmon divisorof numbers.Also write a program to test your function. Write a recursive function,reverseDigits, that takes an integer as a parameter snd returns the number with the digits reversed. Also write a program to test your application.create a function named powerHalf(x, n), where this function is recursive like power(x, n), but it also uses the idea that xn = (x n/2)2 when n is even. Use the global variable countcalls to verify that this version of the power function is more efficient than power(x,n), where n is 0 or a positive integer with the base case that: xn = x * xn-1 use python please
- Implement a recursive function called evens that returns an integer with only theeven numbers. Note this function is returning an integer, not printing. There shouldbe no use of cout within your function. The function declaration should look asfollows:int evens(int n);(ex. evens(234567); returns 246)(ex. cout << evens(56032); prints 602)Fibonacci numbers are a sequence of integers, starting with 1, where the value of each number is the sum of the two previous numbers, e.g. 1, 1, 2, 3, 5, 8, etc. Write a function called fibonacci that takes a parameter, n, which contains an integer value, and have it return the nth Fibonacci number. (There are two ways to do this: one with recursion, and one without.)Write a recursive void function that has one parameter that is a positive integer. When called, the function writes its argument to the screen backward. That is,, if the argument is 1234, it outputs the following to the screen: 4321. I've literally tried to create this program and I have no idea how to make it work. Please help me. Is it possible to explain line by line what the code does?

(Hint: think about adapting the examples myfunction and anotherfunction in Chapter 1.) If an input other than a non-negative integer is entered into your function myfactorial, the process will never halt. Create a new function safefactorial which behaves identically to myfactorial on non-negative integers, but raises a ValueError when other values are entered. Use safefactorial to write a function mybinom (n,r) that re- turns the binomial coefficient ("). Use mybinom (n,r) to write a function hockeystick (n,r) that n H(n,r) = [ (c.). i=r computes H(n,r)
