Explanation:-
A tree is a non-linear and hierarchical data structure that consist of a collection of nodes such that each node of a tree stores a value and list of references to the other nodes (the children). This data structure is the specialized method to organize and store the data in computer to be used more effectively. In a tree there are always root node(that also called as parent node) and child node. For example, in the given tree we can see A is the root node(parent node) and B, C, D are the child node of A.
