Exercise: Fuel Check

You're managing a fleet of 10 spaceships. Each ship's fuel level is stored in an array as a decimal between 0.0 (empty) and 1.0 (full). Your job is to check a specific ship and refuel it if necessary.

Requirements

1. Get a ship number (1-10) from the user
2. Check if that ship's fuel level is at or below 0.25
3. If yes, refuel it to 1.0
4. Print: "Fleet fuel levels: " followed by the array

Remember: Ship numbers are 1-10, but array indexes are 0-9.
