To traverse through a linked list, we typically make a copy of the reference of the front or head node. So, the correct answer is:
Explanation:
- When traversing a linked list, we start from the front or head node and follow the links from one node to the next until we reach the end of the list. To do this, we need to maintain a reference to the current node we are visiting.
- In a singly linked list, each node contains a reference (often called `next`) to the next node in the sequence. So, to move from one node to the next, we need to update our reference to point to the `next` node.
- Therefore, when traversing the linked list, we make a copy of the reference to the front or head node [tex]\tt{(front),~ }[/tex] as it allows us to access the entire list by following the references from one node to the next. This initial reference allows us to start at the beginning of the list and traverse it iteratively until we reach the end.
