-# ('''​points'''​) ​Find and run a PROMELA ​file in both simulation ​and verification mode. Capture ​the output ​in a file and submit it for the answer to this problem.+# ('''​20 points'''​) ​Write a PROMELA ​model that starts no more than '''​N'''​ processes randomly where '''​N'''​ is given with a '''#​define'''​. Here the ''​init''​ process is not part of '''​N'''​. Each of the '''​N'''​ processes should output its process ID in the order of creation. After that, each process should then output its process ID in reverse order of creation ​and then exit before the next process reports its ID and exits. Report the number of states found for '''​N = 5'''​ in verification mode.  
 +# Try a variant of the previous model where the '''​N'''​ processes actually exit in the actual order of creationExplain what happens in this variant of the model?
