Binary Trees

Introduction A binary tree is a hierarchical data structure where each node has at most two children, referred to as the left child and right child. Unlike linear data structures like arrays or linked lists, binary trees organize data in a hierarchical, branching structure that enables efficient searching, sorting, and hierarchical representation. Binary trees are fundamental to computer science and appear in file systems, databases, compilers, and countless algorithms. By the end of this tutorial, you’ll understand different types of binary trees, how to traverse them, and when to use them. Read more →
