"Intersection of Two Linked Lists," involves finding the node where two given linked lists intersect.

You're given the heads of two linked lists that may intersect at some point, and if they do, they become a single linked list from that point forward.

The main idea to solve this problem efficiently is to traverse both linked lists and compare their lengths.

Once the difference in lengths is calculated, you can iterate through both lists simultaneously, starting from the same relative positions from the end. By doing this, you'll eventually reach the intersection node or the end of the lists (indicating no intersection).

If an intersection exists, the algorithm will identify and return the intersecting node; otherwise, it returns null to indicate no intersection point between the lists.

Time Complexity = O(m + n), where ‘m,n’ are the length of the two input lists

Space Complexity = O(1)

My name is David, and I am a software engineer at Meta.

I’ve received three six-figure offers from Google, Meta, and Amazon.

My passion is helping software developers reach the peak of their careers by guiding them to land six-figure dream jobs at top tech companies.

I’m currently in the process of creating a complete guide—with everything you need to succeed in interviews—to help you land a top tech offer.

To all the gladiators in the arena, we’re all in the middle of writing our own stories. The worse the monsters, the more epic the story.

You either get an epic outcome or an epic story. Both mean you win.

Keep crushing. May your desires be greater than your obstacles.

Never quit,
