Problem

Detect if you can connect every * with each other
by not using a * twice.

*** 187
* * -> 2 6 -> yes
*** 345

*** 1
* -> 2 -> no (can't go back to start node)
*** 345

* ** 1 87
* * -> 2 6 -> no (can't go back to start node without using a node twice)
*** 345

Print 'yes' if it is possible, 'no' if it is impossible.
Print 'empty' if no * is found.
Print 'maybe' if there is no space enclosed.
