39. User defined lists - Part B

39. User defined lists - Part B

The chapter discusses the implementation of linked list operations, including appending, inserting, deleting nodes, and creating a string representation of the list. It highlights both iterative and recursive methods for these operations. Key challenges such as deleting nodes and managing empty states are also elaborated upon.

What we have learnt

  • Understanding how to manipulate linked lists through various methods.
  • The importance of handling edge cases in linked list operations.
  • The distinction between iterative and recursive approaches to list management.

Key Concepts

-- Linked List
A data structure that consists of a sequence of nodes, where each node contains data and a reference to the next node.
-- Append
An operation that adds a new node containing a specific value at the end of the linked list.
-- Delete
An operation that removes a node with a specific value from the linked list.
-- Recursive Function
A function that calls itself to solve a smaller instance of the same problem, useful for operations such as traversing and manipulating linked lists.
