Door Open Or Closed

A door starts closed. 1) Open prints Door opened. and remembers the door is open, or Already open. when it is; 2) Close prints Door closed. or Already closed. the same way; 3) Quit prints Goodbye! and leaves the loop; anything else prints Unknown choice - try again.. The close branch is written; write the open branch so the is_open flag is only changed when the action makes sense. Input: one choice per line, ending with 3. Prompts are part of the output, so each message follows Choice: .

Expected Output:

1) Open↵
2) Close↵
3) Quit↵
Choice: Door opened.↵
1) Open↵
2) Close↵
3) Quit↵
Choice: Already open.↵
1) Open↵
2) Close↵
3) Quit↵
Choice: Door closed.↵
1) Open↵
2) Close↵
3) Quit↵
Choice: Goodbye!↵

= newline. The output ends with a newline — print one after the last line.
