I was searching for hard logic problems like for example counterfeit coin problem or the problems about merging two sorted sequences of weighted balls. Whenever I was searching for serious logical problems I couldn't find anything university level (only like 5th or 6th frade level at most). I'm wondering if there is a book containing serious logical problems (and maybe even answers).
