Average of Levels Binary Tree (LeetCode 637) | Solution with easy explanation | Study Algorithms

Binary tree is a very important interview based data structure simply because of the number of ways you can traverse it. This gives birth to a lot of possible use cases and you need to understand it completely. This problem explores the binary tree one level at a time while going through every element. All along with animations and code.

Hi Nikhil, put some light on your journey with SAMSUNG COMPANY.

[@nikoo28]

I will create a video but not sure how much I can disclose. Samsung was one of the companies who are like top secret about everything.. 😅 They didn’t even allow you to take your laptop home.
