Let me ask you a simple question, have you used set, map or list while working with apex? Your answer will most probably be YES. But what if I say, When was the last time you created a binary tree in apex? or a segment tree? a graph? Can you think of any scenario where you thought - ONLY A BINARY TREE CAN SOLVE IT?
If not, what approach did you use to solve such problem? What were the limitations?

In this session, we're going to solve a real life project requirement using an advanced data structure and we'll see the performance impact we're having by using it and learn why it is better than a brute force solution. So, the next time when you face such a requirement, you'll think at the first place - Which data structure should I use to solve it? and then you'll design and implement the most efficient solution.
