Implementing Binary Search Tree Deletion in Python

Handling hierarchical data structures is a core software engineering skill, but deleting nodes from a Binary Search Tree (BST) is famously difficult to implement correctly without breaking tree integrity. This course guides you step-by-step through the logic and code required to handle every deletion scenario with confidence. What you'll learn: - Understand the foundational properties of Binary Search Trees and how deletion affects tree structure. - Implement node deletion for all three critical cases: leaf nodes, nodes with one child, and nodes with two children. - Apply modern Python type hints to represent tree nodes clearly and safely. - Find the inorder successor to correctly swap and remove nodes with two children. - Practice writing clean recursive algorithms that maintain the BST property. - Verify your implementation using basic unit testing patterns to ensure robust code. You will start with core BST definitions and structural concepts before moving into step-by-step recursive implementation, analyzing code snippets, and verifying your logic. This course is designed for beginner to intermediate Python programmers and students of data structures who want to solidify their algorithmic foundations; no prior tree-manipulation experience is required.
