Linked Lists: Finding the Nth Node from the End

Linked Lists are a cornerstone of computer science interviews and competitive programming. Learn how to manipulate these fundamental data structures to solve complex traversal problems with maximum efficiency. By the end of this course, you will not only understand the structure and operation of linked lists but also be proficient in implementing advanced search algorithms, specifically focusing on finding elements relative to the end of the list. This foundational knowledge is crucial for anyone preparing for technical interviews or seeking a deeper understanding of data structures. What you'll learn: * Understand the core concepts of singly linked lists, nodes, and pointers. * Implement linked list creation and basic operations using modern Python class structures and type hints. * Apply the double iteration method for calculating list length and locating specific nodes. * Master the efficient two-pointer (fast and slow pointer) technique for end-relative traversal. * Practice analyzing the time and space complexity of different linked list algorithms. The course begins with defining the linked list structure and basic traversal. We then dive into two distinct, efficient algorithmic patterns—double iteration and the two-pointer approach—analyzing why the latter is preferred in many professional settings. This course is designed for absolute beginners in data structures, including students and aspiring developers. No prior knowledge of linked lists or advanced algorithms is required, though basic familiarity with Python syntax is helpful.
