Determining Dequeued Values in Java Queue Operations
What is the sequence of dequeued values if the following operations are performed on an initially empty queue: enqueue(8) -> dequeue -> enqueue(1) -> enqueue(2) -> dequeue -> enqueue(6) -> dequeue -> dequeue?
1. Enqueue (8):
2. Dequeue:
The first value in the queue is dequeued, which is 8.
3. Enqueue (1):
The value 1 is added to the queue.
4. Enqueue (2):
The value 2 is added to the queue.
5. Dequeue:
The first value in the queue is dequeued, which is 1.
6. Enqueue (6):
The value 6 is added to the queue.
7. Dequeue:
The first value in the queue is dequeued, which is 2.
8. Dequeue:
The first value in the queue is dequeued, which is 6.
Therefore, the sequence of dequeued values is 8126 as per the given operations.
