Implement each of the following functions and write a basic main() function that tests each.

Implement each of the following functions and write a basic main() function that tests each. For convenience, you should be able to find this starter class under Mimir’s assignment 4 starter code.

Do not change the return types, names, or parameters of any of these functions or of the name of the class itself. There is also no need in this assignment for any global variables. You are strongly encouraged to use your solution for some of these functions in others by making a function call (and not by copying and pasting). You are also strongly encouraged to write your own short, helper functions in order to simply things.
