Diameter of a Binary Tree | Dataford Interview Questions

Find the diameter of a given binary tree, optimizing for linear time complexity.

Represent each node as [value, left, right], where a missing child is null. Implement binary_tree_diameter(root) and return the diameter as the number of nodes on the longest path between any two nodes. Return 0 for an empty tree. The input tree is not shared or cyclic.

Constraints

0 <= number of nodes <= 10000
Each node is represented as [value, left, right]
Each value is an integer
A missing child is represented by null
The input is a valid binary tree with no shared or cyclic references

Function Signature

def binary_tree_diameter(root):
