Question 1 of 40Assessment

Given two singly linked lists that merge at some point, what is the most efficient way to find the intersection node?

A. Traverse both lists and store node addresses in two separate stacks, then pop until the nodes differ.

B. Calculate the lengths of both lists, align them by the difference, and traverse together until a match.

C. Concatenate the two lists and use Floyd's cycle-finding algorithm to find the start of the loop.

D. Use a hash map to store all nodes of the first list, then check each node of the second list for existence.
