Programming Rules:

1. Never say "I don't know", say "Let me try"

2. Known to unknown

3. Don't think about entire output

4. think about very next step

5. Introduce a variable only when it simplifies the solution

6. Micro to macro

7. Dry run before you run

8. Every big problem split three part input, progress, output

9. Logic first and syntax next
