My approach to debugging involves first reproducing the issue to understand the context. Then, I analyze the code and use debugging tools to identify the root cause. I also refer to logs and documentation to gather more information. Once I identify the issue, I implement a fix and test thoroughly to ensure the problem is resolved.
