Barbie Linked List

TIP101 Unit 5 Session 2 (Click for link to problem statements)

U-nderstand

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

• What is the correct order for linking the nodes based on the given list?
  • The nodes should be linked in the order they appear: Barbie -> President Barbie -> Weird Barbie -> Ken.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Initialize each named node and link them together to represent the sequence given in the array.

1) Create nodes for each character in the given order using the `Node` class.
2) Set the `next` attribute of each node to point to the subsequent node, forming a chain from the first to the last.

⚠️ Common Mistakes

• Linking nodes in the wrong order, which would misrepresent the sequence given.
• Forgetting to initialize one of the nodes, which would break the continuity of the list.

I-mplement

node_1 = Node("Barbie")
node_2 = Node("President Barbie")
node_3 = Node("Weird Barbie")
node_4 = Node("Ken")

node_1.next = node_2
node_2.next = node_3
node_3.next = node_4
