Instead, every component factors to the following. It is an information construction consisting of a set of nodes which collectively characterize a sequence.
How do you traverse two linked lists?
- Set a pointer p1 to checklist A.
- Set a pointer p2 to checklist B.
- Run some time loop and whereas the nodes pointed by p1 and p2 are usually not identical: If p1 is pointing to NULL, set p1 to go of B. Else, transfer to the following node of A. If p2 is pointing to NULL, set p2 to go of A. …
- Return the node pointed by p1.
