Dijkstra's solution uses one mutex, one semaphore per philosopher and one state variable per philosopher. This solution is more complex than the resource hierarchy solution. This is a C++20 version of Dijkstra's solution with Tanenbaum's changes: The function test() and its use in take_forks() and put_forks() make the Dijkstra solution deadlock-free.
