Unit 5 Session 1 (Click for link to problem statements)
Understand what the interviewer is asking for by using test cases and questions about the problem.
Plan the solution with appropriate visualizations and pseudocode.
General Idea: Sequentially link nodes representing the elements "aries", "taurus", "gemini", and "cancer" to form a linked list.
1) Create a node for each element in the given list and assign each to a variable (head, second, third, tail).
2) Link each node to the next using the `next` attribute to form a sequence:
- Link `head` (aries) to `second` (taurus).
- Link `second` to `third` (gemini).
- Link `third` to `tail` (cancer).
⚠️ Common Mistakes
head = Node('aries')
second = Node('taurus')
third = Node('gemini')
tail = Node('cancer')
head.next = second
second.next = third
third.next = tail
