Traversal in a Singly Linked List
Explore the traversal process in singly linked lists by learning how to visit each node sequentially from head to end. Understand the step-by-step traversal using a temporary pointer, the Java implementation, and the associated time and space complexities. This lesson also highlights common errors and provides exercises to solidify your understanding of linked list traversal.
We'll cover the following...
By now, you understand how a linked list is organized in memory and how the head pointer gives access to the first node. Now, let’s learn how traversal works in a singly linked list. The focus will be on how the next references are followed from node to node and why this leads to linear time complexity.
Linked list traversal
Traversal means visiting each node in the linked list one by one. The process starts from the head and repeatedly follows the next reference until reaching NULL.
As linked lists do not support direct indexing, traversal is required to:
Print all elements in the list.
Search for a specific value.
Count the number of nodes. ...
