This is the 40th Video of our Playlist "Binary Tree : Popular Interview Problems".
In this video we will try to solve a very good Binary Tree problem : Diameter of Binary Tree | Leetcode 543
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Approach Summary :
The logic of the diameterOfBinaryTree method is based on a recursive approach to find the diameter of a binary tree. It utilizes the diameter private method to traverse the tree, calculating the length of the longest path passing through each node. Within the diameter method:
If the current node is null, it returns 0.
It recursively calculates the diameter of the left and right subtrees.
It updates the result variable with the maximum diameter encountered so far, considering the path passing through the current node.
It returns the maximum length between the left and right subtrees plus 1, representing the length of the path from the current node to the deepest leaf.
Finally, the diameterOfBinaryTree method initializes a variable result with the smallest possible integer value, calls the diameter method to compute the diameter, and returns the maximum diameter found.
