DSA Linked Lists Types

This lesson is part of DSA · All levels

Summary

There are three main types of linked lists: single, double, and circular. The singly linked list only points to the next node, the doubly linked list points forward and back so that the traversal can be two-way, while the circular linked list links the last node back to the first node. The type selection is tailored to navigation needs and access patterns.

Key points

Singly linked list has a pointer next only
The doubly linked list has the pointer next and prev for the two-way traversal
Circular linked list connects the last node to the head
Doubly lists are more memory-intensive but easier to delete
