Ranks of processes

The objective is to make N processes print their ranks in respective order (from 0 to N). There are two realizations.

"Train":

Each process prints its rank only after recieving message from previous process (process with rank 0 invokes first);

"Guide":

0 process sends message to process m (m < N) that has to print its rank at this moment. After printing its rank, process m sends message to 0 process. When 0 recieves message from m, 0 sends message to m + 1 and waits for response.
