A team of 99 ninja are each sent out on individual missions by their master. Their master tells the ninja that one of them must come back to the fortress and tell him when all 99 missions are complete – if this ninja is wrong and any mission is incomplete, they will all be slain for incompetence. These ninja are strictly prohibited from seeing each other while outside their fortress, lest they be discovered – they may never meet in person, and may only communicate through a single lantern left in the darkest part of the forest, which they may either turn on or off. Each ninja can visit the lantern whenever he or she wants – there is no danger of accidentally overlapping with another ninja. What plan of communication should the ninja put in place so that at least one of them knows when to return to the fortress?
