Using python 1. Create a stack class using linked list. 2. Provide samples of push, pop; and 3. Using your new class, add a method that reverses a given string without using any built-in reverse methods. Use string below as an example. str_sample = 'Did Hannah see bees? Hannah did.' 4. Create a queue class using linked list. 5. Provide samples of enqueue, dequeue; and 6.Zack and Aerith are set to be married. Lined up in front of them will be the entourage of their closest friends composed of 5 pairs. Biggs and Jessie will march first. Announce their names by pair using queues (i.e. use print)! Make sure to use enqueue and dequeue methods! men = ['Zack', 'Cloud', 'Barret', 'Vincent', 'Cid', 'Biggs'] women = ['Aerith', 'Tifa', 'Marlene', 'Lucrecia', 'Yuffie', 'Jessie'] # Example # "Zack and Aerith!" # "Cloud and Tifa!"

Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
