Binary tree: Binary tree is a hierarchical structure to represent the data. The element of tree is called as a node. Here, the branches are used to connect the nodes. Each node may have zero, one, or two children. A node that does not have a superior node is called the root node. The root node is the starting node, and it is the ancestor for all other nodes in the tree. A node that does not have any children is called as a leaf node or an end node. It is used to implement binary search trees and binary heaps.
