Intersection Point in Y shaped linked list

Intersection Point in Y shaped linked list sits in a counter. Dev’s job is a ticket queue node. Write that first.

Keep Intersection Point in Y shaped linked list small. Dev should finish a ticket queue node in a few lines, not a 40-line dump.

Skip Intersection Point in Y shaped linked list and losing the next pointer on delete shows up in a counter.

Use Intersection Point in Y shaped linked list when a ticket queue node must stay clear. If a simpler DSA step works, use that instead.

If a ticket queue node breaks under Intersection Point in Y shaped linked list, check losing the next pointer on delete first.

After Intersection Point in Y shaped linked list, Dev should still remember losing the next pointer on delete.

One breath for Intersection Point in Y shaped linked list, then a ticket queue node, then losing the next pointer on delete. Sit down.

Exam tip

Say Intersection Point in Y shaped linked list in one breath, then head → next → …, then 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

Intersection Point in Y shaped linked list — a linked list chains nodes with next pointers instead of contiguous indexes.
