This problem considers several ways to compute x" for some n 2 0. 1) Write an iterative function power1 to compute x" for n 2 0. 2) Write a recursive function power2 to compute x" by using the following recursive formulation: x = 1; x1 = (x1/2)2 if n>0 and n is even; x"=x*(x1/2) if n>0 and n is odd. 2. Write a recursive binarySearch function for an array of strings (already sorted), that returns the indexes of all the strings whose first letter is "A" / "a". For example, for anArray = {"Arrow", "art", "box", "curve", "line"}, the search result should show: indexes = {0, 1).

Write a main() function that tests all the above functions, with two test cases for each function. You may create a menu of choices for user to choose which function to test. 5:44 PM ENG US 2022-01-27 0
