Three turtles are lined up in a row. The first turtle said, "I've got 2 turtles behind me and no turtles in front of me." The second turtle said: "I've got 1 turtle behind me and 1 turtle in front of me." but the last turtle surprised the other two and said, "I've got 2 turtles behind me and 2 turtles in front of me."
How is that possible?
If the last turtle had spoken the truh, it seems that the required turtle formation in terms of the conditions of the problem would not be possible.
Consequently, it is my guess that the last turtle must have lied.
