    Three gods A , B , and C are called, in some 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 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.

    ask god A : are you truly ?

    if he says "ja" then he is either true or random

    or he is false or random.

    if he says :"da" then again it would mean the same thing , wouldn't it ?
