## Prompt

Schedule three 30-minute meetings between 9:00 and 12:00 in 30-min slots: Z must be at 11:00; X must occur before Y. Give a valid schedule.

## Response

A valid schedule exists that meets all constraints. Z is fixed at 11:00-11:30, and placing X in an earlier slot than Y satisfies the ordering requirement within the 9:00 to 12:00 window.

## Valid Schedule

| Time | Meeting |
| :--- | :--- |
| 9:00 - 9:30 | X |
| 10:00 - 10:30 | Y |
| 11:00 - 11:30 | Z |

## Constraints Check

- **Z at 11:00:** Z is scheduled for the 11:00-11:30 slot.
- **X before Y:** X at 9:00 occurs before Y at 10:00.
- **30-min slots between 9:00-12:00:** All meetings are 30 minutes, non-overlapping, and within the allowed range.

Other solutions are also valid, for example X at 9:30 and Y at 10:30.

Do you want me to list all possible valid schedules for these constraints?
