Discrete-Event Step

Problem

Apply one event to a queue state. event_type 1 is an arrival (queue length plus 1), event_type 0 is a departure (queue length minus 1, never below 0), and any other event type changes nothing. Return the new queue length.

Hint

Departures from an empty queue are lost.
