Challenge: Inserting Elements in a Linked List
Explore how to implement key linked list operations in C, including counting elements with listLength and inserting nodes at any position using insertAtPos. Understand step-by-step methods to manipulate linked lists efficiently with minimal loops, preparing you to handle dynamic data structures confidently.
Introduction
To practice working with linked lists, you’ll have to implement the following functions:
listLength, which returns the number of elements inside a linked list.insertAtPos, which inserts an element at a specified position inside a list.
The listLength function
Problem statement
Write a function listLength, which takes a list as input and returns the number of elements inside the list.
For example:
- For the list
[1, 2, 3, 4, 5], return5, which is the number of elements. - For the
