LeetCode Learning Assistant

The LeetCode Learning Assistant was developed to empower coders by seamlessly integrating AI-driven guidance directly into LeetCode problem pages. Addressing the need for structured learning during coding practice, it provides a dynamic sliding panel offering hints, detailed algorithmic approaches, pseudocode, Java solutions, and comprehensive complexity analysis. Crucially, instead of revealing the final answer, it meticulously guides users step-by-step through the problem-solving process, elucidating *why* specific approaches are applied and cultivating algorithmic thinking. This methodology actively discourages reliance on pre-made solutions, thereby fostering strong foundational logic. Development challenges included ensuring seamless integration with LeetCode’s dynamic DOM and securely managing Gemini API keys. Built with modern JavaScript and Chrome Extension APIs, the extension features a responsive UI and robust error handling. This tool has proven invaluable in helping coders of all levels significantly enhance their problem-solving abilities, making it an essential asset for interview preparation.
