Do Find Anagrams in a linked list once by hand. head → next → …. Change one input. Say the new result out loud.

Without Find Anagrams in a linked list, a counter gets messy and a ticket queue node is hard to trust.

Exam tip

Board: a ticket queue node. Dry-run Find Anagrams in a linked list. Name the 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

Find Anagrams in a linked list — a linked list chains nodes with next pointers instead of contiguous indexes.
