# Binary Tree Diameter Length

Given a binary tree, you need to compute the length of the diameter of the tree. The diameter of a binary tree is the length of the longest path between any two nodes in a tree. This path may or may not pass through the root
// note: mention time and space complexity of your algorithm.Handle the edge cases.
