Python Recursion: Removing Adjacent Duplicates in Strings

Dealing with repetitive data in strings is a fundamental challenge in coding interviews and real-world text processing. Understanding how to solve these problems recursively builds deep computational thinking and strengthens your problem-solving toolkit. In this text-based course, you will learn how to identify, analyze, and remove adjacent duplicate characters in strings using Python. You will start with key definitions and foundational concepts before moving on to practical implementation. By the end of this course, you will transition from basic string manipulation to writing clean, optimized recursive algorithms with confidence. What you'll learn: - Understand the core principles of recursion, base cases, and the call stack. - Analyze the logic of adjacent duplicate removal and how to approach it step-by-step. - Implement recursive solutions in Python using modern features like type hints. - Compare recursive strategies with iterative approaches using stack data structures. - Write basic test assertions to verify that your string manipulation code works correctly. This course begins with essential terminology, explaining how strings and recursion work at a basic level, before guiding you through the logic and implementation of the removal algorithm. This course is designed for beginner Python programmers and aspiring developers preparing for technical interviews. No prior experience with recursion is required.
