Traversal in a Singly Linked List
Explore how to traverse a singly linked list in Go by visiting each node sequentially from head to end. Understand the process of accessing node data, using a temporary pointer to preserve the head, and avoiding common errors like modifying the head or infinite loops. This lesson helps you implement traversal methods to print elements, search values, and count nodes with a clear grasp of linear time complexity.
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 nil.
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 ...
