What does a node hold?
Short answer. Its data and a link to the next node.
How does the list end?
The last node's link is null.
Nodes and links
| Node | data | next |
|---|---|---|
| start | - | node 1 |
| node 1 | 10 | node 2 |
| node 2 | 20 | null |
Remember
| Node: data plus next |
| Last next is null |
Each clue points to the next. That is a linked list. See the links. Start refers to node one. Node one holds ten, linked to node two. Node two holds twenty; null ends it. Remember. A node holds data and next. The last next is null.
