Why is My Code Not Working? The Developer's Debugging Blueprint

Is your code failing compilation or throwing runtime exceptions? Discover the 5-step debugging blueprint that every senior developer uses to fix bugs fast.

The Senior Debugging Loop

1. **Read the traceback**: Don't ignore the error message! It tells you the exact file, line number, and error type.

2. **Isolate the variables**: Print or log the state of variables right before the error line occurs.

3. **Dry-Run on paper**: Manually trace the loops with simple inputs (like an array of size 3) on a notebook.
