- Is it possible to access the private/ protected data members of a class in any global function? If yes, then give example (preferably code) to justify your answers a classic example of a recursively defined function. It was originallynamed for Leonardo Fibonacci who studied it in the context of predictingthe growth of rabbit populations.Sally and Harry are developing a Coin version. Sally specifies that the class of the single parameter to her compareTo function is Object. Harry defines the input to be of type Coin because he is aware that it will always be called on items of that type. Which approach is appropriate for placing Coin items in an OrderedVector?
- Template functions are considered to be an efficient alternative of function overloading. Justify this statement by comparing the pros and cons of both with real-world examples.Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counterclass is passed as a parameter, the countproperty of that instance should be incremented based on the number of recursive calls. The __str__ method should return the countproperty's value as a string. Please can you change the solution to this problem here, because this is wrong.

- Write an iterative function that determines the number of even elements in an array a of integers of size n. The function should return the number of elements that are even in array a of size n. Propose an appropriate prototype for your function and then write its code. Write a recursive function to solve the above problem. Propose an appropriate prototype for your function and then write its code.Sally and Harry are developing a Coin version. Sally specifies that the type of the single parameter to her compareTo function is Object. Harry defines the parameter to be of type Coin since he is aware that it will always be called on objects of that type. Which approach is appropriate for putting Coin items into an OrderedVector?Give a recursive definition of the function that takes ? (?ℎ??? ? ∈ ℕ) and gives the number of strings of length ? over the alphabet Σ = {0,1,2} that contain two consecutive symbols that are the same.
- Implement a recursive C++ function which takes an integer array (A) and the starting (start) and ending(end) indices of that array, and returns the sum of all elements present in that array. The prototype ofyour function should be:int findSum (int* A, int start, int end)Consider the definition of the class product Type as given in Exercise 8. Which function members are accessors and which are mutators? (4)Develop a Java function that returns true if every element of an array is inside another array. The function should return false if otherwise.
