Essential algorithms and data structures

Data structures

Supported by some programming languages within the command set, programmers often implement these structures using the fundamental data structures as building blocks.

What is a binary tree?

A binary tree is a data structure consisting of nodes and pointers.  It is a special case of a graph where each node can only have zero, one or two pointers.  Each pointer connects to a different node.The first node is known as the root node.  The connected nodes are known as child nodes, while the nodes at the very bottom of the structure are referred to as leaf nodes.
