The question on a qualifying exam (I believe for a PhD in Computer Science) was: "Pose a problem which would be suitable for a qualifying exam and give a solution." The answer my friend gave (for which he got full credit) was: "Pose a problem which would be suitable for a qualifying exam and give a solution." He then answered the question he had posed, as follows: "Pose a problem..." (well, you know the rest) I think this is a rather novel approach to such a problem. Since the original question appeared on a qualifier, that was apparently *a priori* proof that it was suitable for a qualifier. Hence the answer must be valid. --Jeremy Epstein BTL HO, ...!ihnss!houxp!jje
