Adds an attribute to the end of the numerical data (i.e. new last column) that is equal to $\frac{x_1^3}{x_5}$ for each observation. In other words, for each instance, you will cube the $x_1$ column and then divide by the $x_5$ column. 2. Drops the entire $x_4$ feature column if the passed function argument `drop_x4` is `True` and doesn't drop the column if `drop_x4` is `False`. (See further instructions below.) You must name your custom transformer class `Assignment4Transformer`. Your class should include an input parameter called `drop_x4` with a default value of `True` that deletes the $x_4$ feature column when its value is `True`, but preserves the $x_4$ feature column when you pass a value of `False`. This transformer will be used in a pipeline. In that pipeline, an imputer will be run *before* this transformer. Keep…In this assignment, you will create a Linked List data structure variant called a “Circular Linked List”. The Node structure is the same as discussed in the slides and defined as follows (we will use integers for data elements): public class Node { public int data; public Node next; } For the Circular Linked List, its class definition is as follows: public class CircularLinkedList { public int currentSize; public Node current; } In this Circular Linked List (CLL), each node has a reference to an existing next node. When Node elements are added to the CLL, the structure looks like a standard linked list with the last node’s next pointer always pointing to the first. In this way, there is no Node with a “next” pointer in the CLL that is ever pointing to null. For example, if a CLL has elements “5”, “3” and “4” and “current” is pointing to “3”, the CLL should look like: Key observations with this structure: The currentSize is 3 meaning there…
