Circular List Application

Circular List Application is a DSA topic. In plain words you use it for a short Circular List Application example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Circular List Application example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Circular List Application.

From the example next to this theory: Circular List Application — a linked list chains nodes with next pointers instead of contiguous indexes.

Trap — only saying “Circular List Application” with no example. Fix that before you talk about advanced DSA.

Viva: what is Circular List Application? Then show the smallest Circular List Application example you can type. Then name the trap.

Exam tip

What is Circular List Application? Show this: the smallest Circular List Application example you can type. Trap: only saying “Circular List Application” with no example.

Example

class Node:
    def __init__(self, val, next=None):
        self.val = val
        self.next = next

head = Node(1, Node(2, Node(3)))
cur = head
while cur:
    print(cur.val, end=" -> " if cur.next else "\n")
    cur = cur.next

Circular List Application — a linked list chains nodes with next pointers instead of contiguous indexes.
