Module 6 : Linked List
By the end of this module, students will be able to:
- Understand the concept and structure of linked lists
- Differentiate between arrays and linked lists
- Implement singly linked lists in C
- Perform basic operations: insertion, deletion, traversal, and searching
- Understand doubly linked lists and circular linked lists
- Apply linked lists to solve real-world problems
- Debug common linked list errors
- Analyze time and space complexity of linked list operations
