NettetLinked list is a linear data structure where each node only points to its next node. So during this process, we should keep track of previous node using some pointer. Before changing the next pointer of the current node, we also need another pointer to … Nettet2. sep. 2024 · Linked List: head → 1 → 2 → 3 → 4 → 5 → NULL So, Essentially, we can just swap the values of node such that: Node 1’s data with Node 5’s data. Node 2’s data with Node 4’s data. Node 3’s data is swapped with itself. Our input linked list after swapping the node values will be: head → 5 → 4 → 3 → 2 → 1 → NULL.
