Linked List Intersection

Return the node where two singly linked lists intersect. If the linked lists don't intersect, return null.

Example:

Output: Node 8

How the custom test cases work:

The input is designed to describe how the two input linked lists intersect. Here's how the skip inputs work:

• skip_A: The number of nodes to skip in list A (from the head) to reach the intersection node.
• skip_B: The number of nodes to skip in list B (from the head) to reach the intersection node.

For a linked list with no intersection, set skip_A and skip_B to the length of their respective linked lists, which effectively skips all nodes in each linked list.
