Decimal Equivalent of Binary Linked List

Decimal Equivalent of Binary Linked List is a DSA topic. In plain words you use it for a ticket queue node in a counter. Don’t start with a slogan — start with that picture.

Smallest example: head → next → …. Type it, run it, and say what you see. If you can do that from memory, you know Decimal Equivalent of Binary Linked List.

From the example next to this theory: Decimal Equivalent of Binary Linked List — a linked list chains nodes with next pointers instead of contiguous indexes.

Trap — losing the next pointer on delete. Fix that before you talk about advanced DSA.

Viva — what is Decimal Equivalent of Binary Linked List? Then show head → next → …. Then name the trap.

What is Decimal Equivalent of Binary Linked List? Show this: head → next → …. Trap: losing the next pointer on delete.

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

Decimal Equivalent of Binary Linked List — a linked list chains nodes with next pointers instead of contiguous indexes.
