- Check My Work Here is an algorithm for calling a friend on the telephone: Step Operation 1. Dial the phone and wait for either an answer or a busy signal 2. If the line is not busy then do Steps 3 and 4 3. Talk as long as you want 4. Hang up the phone, you are done 5. Otherwise (the line is busy) 6. Wait exactly 1 minute 7. Go back to Step 1 and try again During execution, this algorithm could get into a situation in which, as in the deadlock problem, no useful work can ever get done.
