show that one can always build a red-black tree with n nodes such that there's no more than O(log n) red nodes
Given a binary tree, let an H-node be defined as a non-leaf node in the tree whose value is greater than or equal to its children nodes (1 or 2 children).
Write a function, countHNodes(), that returns the number of H-nodes in a binary tree (pointed by p) using recursion.
The result of Prim's method is always a Minimum Spanning Tree, but why is that?
