Question
Insertion takes place at the ______ of the queue and deletion at the ______ of the queue.
Options:
- front, front
- front, end
- end, front
- end, end
Solution
In a queue, the insertion of elements occurs at the rear (or end) of the queue, while deletion takes place at the front of the queue. Therefore, the correct answers to the fill-in-the-blank statements are as follows:
- Insertion takes place at the end of the queue and deletion at the front of the queue.
This structure allows for a FIFO (First In, First Out) operation, meaning that the first element added to the queue will be the first one to be removed. In other words, the elements are processed in the same order they arrive, which is critical in scenarios such as task scheduling and managing requests in a system, ensuring that each request is handled in the order it was received.
