Data structure is a fundamental concept in computer science that deals with organizing and manipulating data efficiently. One of the key data structures is a binary tree, which consists of a finite set of nodes that are either empty or contain a root node with two disjoint binary trees as its left and right subtrees. A binary tree is characterized by various properties and operations such as nodes, edges, paths, children, parents, ancestors, descendants, depth, level, height, subtrees, leaf nodes, and internal nodes. These concepts help in understanding the structure and operations that can be performed on a binary tree. One important aspect of a binary tree is its classification into full and complete binary trees. A full binary tree is a tree in which each node has either zero or two children, while a complete binary tree is a tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible. In summary, a binary tree is a versatile data structure that can be used to efficiently store and retrieve data in various applications. Understanding the properties and operations associated with binary trees is essential for developing efficient algorithms and solving complex problems in computer science.
