Chapter 18: Problem 9

When an element is added to a queue, where is it added?

Short Answer

Expert verified

Answer: When an element is added to a queue, it is inserted at the Rear end of the queue. The queue follows the First In First Out (FIFO) principle to maintain the order, ensuring that the oldest element is always at the front and removed first.

Step by step solution

Introduction to Queue

A queue is a linear data structure that follows the First In First Out (FIFO) principle, which means that the first element inserted into the queue will be the first one to be removed. Queues are used to store elements in a specified order and ensure that the oldest element is always at the front.

Queue Structure

In a queue, there are two important pointers - Front and Rear. The Front pointer represents the start of the queue where an element can be removed. The Rear points to the end of the queue, where a new element can be added.

Add Element to Queue

When an element is added to the queue, it is inserted at the Rear end of the queue. It always gets added in the last position (after the current Rear element) maintaining the FIFO principle.

Example of Adding an Element

Suppose a queue already has elements A, B, and C in that order (A at Front and C at Rear). If a new element D is added to the queue, it will be inserted at the Rear end of the queue. The updated queue will look like this: A(front)-B-C-D(rear).

Summary

In summary, when an element is added to a queue, it is added at the Rear end of the queue, following the First In First Out (FIFO) principle. This ensures that the elements retain their order and are removed in the sequence they were inserted.
