Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements, dequeue 4 elements, and then enqueue 7 more elements. Which indices of the internal array elements hold the value null, that is, do not hold an element?

0 and 1
2 and 3
8 and 9
9 and 10
9 and 1
If N represents the number of elements in the queue, then the size method of the LinkedQueue class is O(N).

C++ language
We are given a Queue data structure that supports standard
operations like Enqueue() and Dequeue(): Enqueue(element): add a
new element at the tail of the queue; Dequeue(): delete the element
at the head of the queue.
Show how to implement a stack using two queues. Analyze the
running time of the stack operations: Push and Pop.

True False
The enqueue and dequeue operations in a priority queue take O(lg
n) time, while linked list and array implementations take O(1)
time.
A binary heap is a (nearly) complete binary tree.
Heaps usually use a linked node structure for
implementation.
When implementing heaps as arrays, you can leave a blank space
at the front. If you do, the parent of a node at index i can be
found at index floor(i/2).
When implementing heaps as arrays, if you...

Give an algorithm for reversing a queue Q. Only following
standard operations are allowed on queue. 1. enqueue(x) : Add an
item x to rear of queue. 2. dequeue() : Remove an item from front
of queue. 3. empty() : Checks if a queue is empty or not.. (Hint:
you can use LinkedList, Stacks, and Queues from the java data
collection)
OUTPUT Examples: Input : Q = [10, 20, 30, 40, 50, 60, 70, 80,
90, 100] Output :Q =...
