LINKED LIST IN PYTHON Create a program using Python for the different operations of a Linked List. Your program will ask the user to choose an operation. 1. Create a List -Ask the user how many nodes he/she wants. -Enter the element/s -Display the list -Back to menu 2. Add at beginning -Ask for the element to be inserted. -Display the list -Back to menu 3. Add after -Ask for the element to be inserted. -Ask for the position AFTER which the element is to be inserted -Display the list -Back to menu 4. Delete -Ask for the element (data) to be deleted -If found, delete the node with that data. -If multiple values, delete only the first element found -If not found, display that the element is not found -back to menu 5. Display -Display the list 6. Count -Display the number of elements 7. Reverse -Reverse the list and display it 8. Search -Ask the user for the element (data) to be searched -Display a message if the element is found or not 9. Quit -Exits the program
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).
