Suppose you implemented a basic (singly) LinkedList class in Python. This Linked ist class contains three attributes, ie., size, head, and tail. This LinkedList can be used to manipulate an unordered list of numeric values, with function insert(self, value, index), remove (self, value, index), traverse (self), is_empty(self), and size (self). The traverse function could print a sequence of values by visiting each node in the Linked ist from head to tail.
