In a Fibonacci sequence, each number is the sum of the two preceding ones, starting from 0 and 1. The beginning of the sequence is: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... Write a C++ program, no need to be object-oriented, to find the nth number in a Fibonacci sequence using two different approaches. Each approach is implemented by a function that takes n as its only parameter. One function solves the problem only recursively. The other function solves the problem recursively but with the support of dynamic programming. For the dynamic programming implementation, you are allowed to define the needed array as a global variable. You are not allowed to use any loop in your functions. The only loop you will need in your program is the one in the main() function, right before calling the dynamic version function. You need this loop to initialize all elements in the array to an invalid Fibonacci number (e.g., -1) to keep track of the array elements that do not have a Fibonacci number calculated yet. Test your code with n values 5, 10, 20, 30, 40
