## Prompt

Minimize total time to finish these tasks, one at a time, respecting dependencies: A (2h, no deps); B (3h, needs A); C (1h, no deps); D (2h, needs B and C). Give a valid order and the total time.

## Response

A valid dependency-respecting order is **A → B → C → D**.

Total time:

\[
2 + 3 + 1 + 2 = 8\text{ hours}
\]

**Total: 8 hours.**

What-if you instead schedule **C before B**?
