2 Practical 2.1 Recursion Recursion is a concept used in programming to define a solution that is itself defined in terms of smaller instances of the same solution In this way, recursion is different to iter- ation in thatt achieves a solution through repeated function calls to the same function that behave differently based on the current problem state. Recursion is very useful for solving many problems as it enables a problem to be broken down into repeated solution steps that can become increasingly fine grained. Recursion is incredibly powerful. Even without the use of iterative statements like while and for recursive solutions are capable of doing anything an iterative solution can do. In some cases, recursion might seem more intuitively suited and in others not Additionally, you will be not be provided with mains. You must create your own main to test that your code works and include it in the submission which will be overwritten during marking 2.2 Task 1 In this task, you are going to implement a linked list, as you have done before, but the difference is that this time, you will do so using recursion in place of where you normally you would have used iterative methods. 2.2.1 rLL The rLL is the recursive linked list class. It has the following definition based on the simple UML diagra below: -head: item -size: int
