Count of good nodes | Leetcode

This video explains how to count good nodes in a given binary tree which is a very important recursion based tree problem for interview. It is from leetcode 1448. In this problem, a good node is a node which do not have any other node from root to current node path which is greater than the current node. All such nodes are good nodes and our goal in this problem is to return the count of good nodes.
I have first explained the idea of the problem using examples followed by the bruteforce approach to solve it. Later, I have also shown the optimization technique with intuition and code walkthrough at the end of the video.
