Split a Circular List into 2 Halves

Split a Circular List into 2 Halves is a DSA topic. In plain words you use it for a short Split a Circular List into 2 Halves example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Split a Circular List into 2 Halves example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Split a Circular List into 2 Halves.

From the example next to this theory: Split a Circular List into 2 Halves — a linked list chains nodes with next pointers instead of contiguous indexes.

Trap — only saying “Split a Circular List into 2 Halves” with no example. Fix that before you talk about advanced DSA.

Viva: what is Split a Circular List into 2 Halves? Then show the smallest Split a Circular List into 2 Halves example you can type. Then name the trap.

Exam tip

What is Split a Circular List into 2 Halves? Show this: the smallest Split a Circular List into 2 Halves example you can type. Trap: only saying “Split a Circular List into 2 Halves” 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
