Intersection of Two Linked Lists Given the heads of two singly linked lists headA and headB, return the node at which the two lists intersect. If the two linked lists have no intersection at all, return null. It is guaranteed that there are no cycles anywhere in the entire linked structure. Note : The solution should return the actual Node object, not its value. If no intersection, return null. Input Specification Input consists of two linked lists, represented by their head nodes headA and headB. For clarity in examples, the list contents are shown as arrays, but they represent linked list structures where the intersection point refers to the same memory address for a node. Output Specification Return the intersecting Node object. If there is no intersection, return null. Constraints No specific constraints are provided for the number of nodes or node values.
