Systematically isolate and fix code issues using structured debugging methodologies.

• Covers six-step debugging workflow: information gathering, reproduction, isolation, root cause analysis, fix implementation, and verification
• Includes common bug patterns (off-by-one, null references, race conditions, memory leaks, type mismatches) with targeted solutions
• Provides debugging techniques: binary search isolation, print/log debugging, divide-and-conquer code elimination, and regression test patterns
• Supports multiple languages with tool recommendations (pdb/cProfile for Python, Chrome DevTools for JavaScript, Delve for Go, etc.)
