Three gods A, B, and C are called, in no particular order, True, False, and
Random. True always speaks truly, False always speaks falsely, but whether
Random speaks truly or falsely is a completely random matter. Your task is
to determine the identities of A, B, and C by asking three yes-no questions;
each question must be put to exactly one god. The gods understand English,
but will answer all questions in their own language, in which the words for
yes and no are da and ja, in some order. You do not know which word means
which. |
