Give an example of a deadlock involving only a single process and a single resource.

What will be an ideal response?

A recursive process that acquires a lock on a resource. The process will acquire the lock, then execute a recursive call. When it tries to reacquire the lock, it will block. However, because it will be blocking on itself and has no way to release the lock once it has blocked, it will become deadlocked. Also, a process could wait on an event that will never occur because no provision has been made to signal the event.
