Two logican are walking in a forest and is stopped by a giant. The giant knocks both of them unconscious and tattoos both of their head. He then throws the two logican into a cave, with no light whatsoever. When the two logican wakes up, they are told that only one of them have a tatoo on his head. If one of the logican were to walk out of the cave in the morning and he doesn’t have a tattoo, he will be killed. The two logican cannot communicate whatsoever [no talking, no signs, nothing]. Everyday, in the morning the cave would be opened by the giant and that is the only time the two logican can see each other [but still no communication whatsoever].
On what day can the two logican leave the cave? Why?
