What's this code going to display? Careful, though: it's a trap!

Swee-heet! "Ackbar" isn't a key but a value, so nothing gets removed, isEmpty returns false and the key-value pairs in fleet are printed.

Yikes! "Ackbar" isn't a key but a value, so nothing gets removed, isEmpty returns false and the key-value pairs in fleet are printed.
