Linking Nodes

Unit 5 Session 1 (Click for link to problem statements)

U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

• How do nodes in a linked list reference each other?
  • Each node has a next attribute that can be set to point to another node, linking them together in sequence.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Set the next attribute of node_one to node_two to link these nodes sequentially.

1) Assign `node_two` as the `next` attribute of `node_one` to create a link between the two nodes.

⚠️ Common Mistakes

• Failing to initialize the next attribute properly, which might not establish the link.
• Confusing the assignment direction, e.g., setting node_two.next = node_one instead of the correct order.

I-mplement

node_one.next = node_two
