Which Veteran and Rookie Pilots Fit the Payroll
Problem
Table: `pilots`
| Column Name | Type |
|---|---|
| pilot_id | int |
| rank | enum |
| wage | int |
`pilot_id` is the primary key. `rank` is one of `('Veteran', 'Rookie')`. `wage` is the pilot's annual wage.
An airline has a hiring budget of `50000`. It first hires `Veteran` pilots, cheapest wage first (ties broken by smaller `pilot_id`), taking each while the running total of veteran wages stays within budget. With the leftover budget it then hires `Rookie` pilots under the same cheapest-first rule. Return the `pilot_id` of every pilot actually hired, in any order.
