Solution

The correct option is A Sorted array
Priority queue:
1. Via linked list : Insertion = O(n) , Deletion =O(1), Search = O(n)
2. Via Sorted array : Insertion = O(n) , Deletion = O(1) , Search =O(logn)
3. Via Unsorted array : Insertion =O(1) , Deletion = O(n), Search =O(n)
4. Via Heap list : Insertion =O(logn), Deletion = O(logn), Search = O(n)

Q. Suppose a circular queue of capacity (n - 1) elements is implemented with an array of n elements. Assume that the insertion and deletion operations are carried out using REAR and FRONT as array indeed variables respectively. Initially, REAR = FRONT = 0. The conditions to detect queue full and queue empty are

Q. A queue is implemented using an array such that n ENQUEUE and DEQUEUE operations are performed efficiently. Which one of the following statements is CORRECT (n refers to the number of items in the queue)?

Q. Suppose you are given an implementation of a queue of integers. The operations that can be performed on the queue are:

(i) is Empty (Q) : returns true if the queue is Empty, false otherwise.
(ii) delete (Q) : delete the elements at the front of the queue and returns its value.
(iii) insert (Q, i) : insert the integer i at the rear of the queue.

Consider the following functions:

void f (queue Q)
{
int i;
if (! is Empty (Q))
{
i = delete (Q);
f(Q);
insert (Q, i);
}
}

What operation is performed by the above function f?

Q. A circular queue has been implemented using a singly linked list where each node consists of a value and a single pointer pointing to the next node. We maintain exactly two external pointers FRONT and REAR pointing to the front node
and the rear node of the queue, respectively. Which of the following statements is/are CORRECT for such a circular queue, so that insertion and deletion operations can be performed in O(1) time?
I . Next pointer of front node points to the rear node.
II . Next pointer of rear node points to the front node.

Q. A priority queue is implemented as a max-heap initially, it has five elements. The level-order traversal of the heap is as follows:
20, 18, 15, 13, 12
Two new elements '10' and '17' are inserted in the heap in that order, The level-order traversal of the heap after the insertion of the element is
