Trees are hierarchical data structures consisting of a root node and one or more child nodes for each parent node. Each node can have a maximum of one parent and multiple child nodes. Trees are commonly used in various applications, including searching, sorting, and representing hierarchical relationships.

Key Features of Trees:

Root Node: The topmost node in the tree, representing the entire data set.
Parent-Child Relationships: Each node is associated with one parent node, and it may have multiple child nodes.
Hierarchy: Nodes are arranged in a parent-child structure, with the root node being the highest and the leaf nodes being the lowest.

Types of Trees:

Binary Tree: A tree in which each node has at most two child nodes, resulting in a balanced tree.
B-Tree: A binary tree where the left and right subtrees have the same size on average, promoting efficient search and traversal.
Heap Tree: A tree that satisfies the heap property, where the root node is the maximum or minimum value in the subtree.

Applications of Trees:

Search: Trees allow efficient searching for specific nodes in the data set.
Sorting: Trees can be sorted in ascending or descending order based on their node values.
Representing Hierarchies: Trees are commonly used to represent hierarchical relationships between entities.

Examples:

A binary tree with the following structure:

C D E

A B-tree with the following structure:
