Understanding Queues in Computer Science

Which of the following operations is not typically associated with a queue?

• Enqueue

• Dequeue

• Peek

• Sort

What is the primary difference between a circular queue and a linear queue?

• A circular queue has a fixed size, while a linear queue does not.

• A circular queue allows elements to be added at both ends, while a linear queue does not.

• In a circular queue, the last position is connected back to the first position, while in a linear queue it is not.

• A circular queue is implemented using arrays, while a linear queue is implemented using linked lists.

Which of the following is an application of queues?

• Depth-first search in graphs

• Function call management in recursion

• Breadth-first search in graphs

• Sorting algorithms

In a priority queue, how are elements removed?

• In the order they were added

• Based on their priority

• Randomly

• From the middle of the queue

Which data structure is commonly used to implement a queue?

• Stack

• Array

• Tree

• Graph

What is the time complexity of enqueuing an element in a queue implemented using a linked list?

Which of the following is a type of queue where each element is assigned a priority?

• Circular Queue

• Double-ended Queue

• Priority Queue

• Simple Queue

In a circular queue of size 5, if the front is at index 2 and the rear is at index 4, where will the next element be enqueued?

• Index 0

• Index 1

• Index 3

• Index 5

Which of the following is not a characteristic of a queue?

• First In First Out (FIFO) order

• Elements can be added at both ends

• Elements are removed from the front

• Elements are added at the rear

What is the main advantage of using a circular queue over a linear queue?

• It allows for dynamic resizing

• It prevents memory wastage by reusing empty spaces

• It is easier to implement

• It allows for faster access to elements
