Any node that has a child is called a parent node. The descendents of the parent node are child nodes. Most nodes can be parents of children and children of other parents.

You will have to read the Tree datastructure before solving such a problem, the Parent and Child nodes are the alphabet of the Tree structure : Read the Terminology of a Tree (data structure) and Binary tree
