Hey everyone,

Nowadays many Top MNC's companies focus on Segment Tree. So In this post, I am going to cover Segment Tree also along with some important placement coding problems on Segment Tree. And I have made videos on Segment Tree for the proper understanding of the concepts. As you know Segment Tree is one of the hardest topics and understanding it is very important and I will try to explain as much as I can.

Content on the Videos:

1. Introduction to Segment Tree
   1. What is a Segment Tree?
   2. How to Build a Segment Tree?
   3. How to Find a Range Query Problem Using Segment Tree?

And I have attached some important questions on Segment Tree:
