Es ist möglich, eine Queue zu implementieren, die mithilfe eines dynamischen Arrays beliebig vergrößert oder verkleinert werden kann. Zum Beispiel mitstd::vectorin C++ bzwArrayListauf Java. Anwendungen einer Queue: Breitensuche (BFS)Algorithmus. Job Scheduling, um eine Queue von Prozesse...
C++ Program When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period. d = gt2 The variables in the formula Construct a heap first by using the bottom-up algorithm and then by using the top...
