The diameter of an N-ary tree is the length of the longest path between any two nodes in the tree. This path may or may not pass through the root. (Nary-Tree input serialization is represented in their level order traversal, each group of children is separated by the null value.) Exam...
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. Example: Given a binary tree1 /\2 3 /\4 5Return3...
