A perfect binary tree is a binary tree in which all interior nodes have two children and all leaves have the same depth or same level.An example of a perfect binary tree is the (non-incestuous) ancestry chart of a person to a given depth, as each person has exactly two biological paren...
Given a complete binary tree, count the number of nodes. Definition of a complete binary tree from Wikipedia: In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 and 2h...

Can you solve this real interview question? Count Complete Tree Nodes - Given the root of a complete binary tree, return the number of the nodes in the tree. According to Wikipedia [http://en.wikipedia.org/wiki/Binary_tree#Types_of_binary_trees], every
The distribution method described in this paper shows how optimized distribution of packets takes place for complex computations in ring connected binary tree. The controller node acts as a centralized node which creates the sub processing tasks and distributes to the computation nodes. The ...
