Why This Matters

Binary Search Trees (BSTs) are fundamental data structures that underpin many complex systems in computer science. They are used in databases to optimize search operations and in-memory storage systems to maintain sorted data efficiently. Mastery of BSTs is crucial for coding interviews as they are a frequent topic, testing a candidate's understanding of data organization and algorithmic efficiency.

Before You Read

🤔 Prerequisite Check: Before diving in, can you answer this question? What do you know about binary trees, and how they differ from binary search trees?

Core Concepts

Binary Search Trees are a special kind of binary tree where each node has at most two children. The key property of BSTs is that the left child of a node contains only nodes with values less than the parent node, and the right child only nodes with values greater than the parent. This property makes BSTs efficient for search operations.

Here's a simple analogy: Imagine a library where books are sorted on shelves. The leftmost shelf contains books with titles starting from 'A'
