  2. Initialize two sets: one for found keys and one for boxes we've encountered but can't open yet.
  3. While the queue is not empty, process the box at the front.
  4. Collect candies from the current box.
  5. Add any keys found to the set of found keys.
  6. Add any contained boxes to the queue if they can be opened, or to the set of encountered boxes otherwise.
  7. Check if any encountered boxes can now be opened with the found keys, and if so, move them to the queue.
  8. Repeat until the queue is empty.
  9. Return the total number of candies collected.
