- Write a recursive function rec_string that produces the output shown below for the corresponding function calls. Write a main function to test the function. Method call rec_string(‘abcde’), will produce the following output: * e de cde bcde abcde Method call rec_string(‘abc’), will produce the following output: * c bc abcIn this assignment you will write your own square root function and a main program to test it. Thesquare root function will return a tuple the includes the square root of the number as well as thenumber of iterations it took to arrive at that solution. The pseudocode for the function and mainprogram is given as follows:import mathEPSILON = 1.0e-14def square_root(number):approximation = 1previous = 0iterations = 0while ((absolute value of (approximation * approximation minus number)is greater than EPSILON) and previous != approximation):previous = approximationapproximation = 0.5 * (approximation + number / approximation)iterations += 1return (approximation, iterations)print('This program calculates the square root of an inputted number')print('and the number of iterations that the algorithm took to reach')print(f'a degree of accuracy of {EPSILON}.')answer = “yes”while answer[0] equals “Y” or answer[0] equals “y”:number = float(input('Enter a nonnegative number: '))while number is less…(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
