1. Question 1 (4 points)

Analyze the snippet of code below. This snippet of code is using a queue. Identify whether the queue is a regular queue or a priority queue. Explain how the queue behaves when the tail reaches the end of the queue.

1. Answer (Multiple Choice):
2. (_) This is a regular queue and hence not a priority queue. When the tail reaches the end of the queue, the tail is made to walk backward in the queue.
3. (_) This is a priority queue. When the tail reaches the end of the queue, it is set to the index of the array location that has the lowest priority.
4. (_) This is neither a regular queue nor a priority queue. When the tail reaches the end of the queue, it wraps around.
5. (X) This is a regular queue and hence not a priority queue. When the tail reaches the end of the queue, it wraps around.

Explain your answer:

public void Enqueue(int newElement) \{ Q [ tail ]= newElement; if (head ==1 ) head =0; else if ( [ head] = tail; \} if ((( tail +1)
