Given the root of a binary tree, return 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 ...

The diameter of a binary tree is the longest path between any two nodes, measured by the number of edges. This path can pass through or exclude the root. To find the diameter, we need to examine the ...
