A binary tree is defined as either empty or consisting of a root element and two distinct subtrees: left and right. This chapter explores the fundamental concepts of binary trees, including their structure, the significance of external path length, and various traversal methods such as pre-order, in-order, and post-order traversals. Understanding these concepts is crucial for grasping more complex data structures and algorithms in computer science.
