Class Kata „Priority Queue“
Write a class that implements a queue that holds a priority for each element. Elements with a high priority are placed in front of elements with a lower priority. Elements with the same priority are ordered in the order they where inserted into the queue.
The interface of the class has to look like the following:
class PriorityQueue {
void Enqueue(T element, int priority) {...}
T Dequeue() {...}
int Count() {...} // Number of elements in the Queue
}
Example:
| Action | Queue |
| new PriorityQueue<int>() | |
| Enqueue(1, 5) | (1,5) |
| Enqueue(2, 5) | (1,5), (2,5) |
| Dequeue() -> 1 | (2,5) |
| Enqueue(3, 7) | (3,7), (2,5) |
| Enqueue(4, 7) | (3,7), (4,7), (2,5) |
| Enqueue(5, 3) | (3,7), (4,7), (2,5), (5,3) |
| Count() -> 4 |
