Understand the structure and behavior of singly linked lists and how they differ from arrays in memory management and traversal.
Create linked list nodes using Swift generics, allowing for reusable, type-safe data structures.
Implement common linked list operations including insertion, deletion, and traversal from scratch.
Reverse a singly linked list in-place, using pointer manipulation and without additional data structures.
Detect and handle cycles in a linked list using Floydβs Cycle Detection Algorithm (Tortoise and Hare approach).
Find the middle node of a linked list efficiently with fast and slow pointers.
Remove the nth node from the end of a linked list using a one-pass two-pointer technique.
Check whether a linked list is a palindrome by reversing and comparing segments of the list.
Merge two sorted linked lists in linear time without creating new nodes.
Apply Swiftβs reference type behavior to safely and effectively manipulate linked list nodes and avoid common pointer errors.
