Stacks, Queues, and Linked Structures · Linked Structures

Types of Linked List

Singly, doubly, and circular linked lists provide different navigation and update tradeoffs.

Student Focus

Students learn why extra references can simplify operations but increase bookkeeping.

Guided Lesson Notes

How Code Scholars teaches Types of Linked List

This guide helps students understand the idea, implement it carefully, explain the runtime, and recognize when the pattern belongs in a larger problem.

In a session, students usually start with a small trace, then write or review code, then test edge cases. The final step is a short explanation: what the structure or algorithm stores, why it is correct, and what changes when the input grows.

Key Ideas

  • Singly linked lists
  • Doubly linked lists
  • Circular list behavior

Practice Prompts

  • Compare deletion with singly and doubly linked nodes.
  • Design a small circular playlist structure.
