Questions & Step-by-Step Solutions
In which scenario would a circular queue be preferred over a regular queue?
Step 1: Understand what a queue is. A queue is a data structure that follows the First In First Out (FIFO) principle, meaning the first element added is the first one to be removed.
Step 2: Learn about a regular queue. In a regular queue, when elements are removed, the space they occupied is not reused until the queue is emptied.
Step 3: Understand what a circular queue is. A circular queue connects the end of the queue back to the front, allowing the space of removed elements to be reused.
Step 4: Identify scenarios with limited memory. In situations where memory is limited, it's important to use space efficiently.
Step 5: Compare the two types of queues. A circular queue can reuse space from removed elements, while a regular queue cannot.
Step 6: Conclude that circular queues are preferred in scenarios with limited memory because they make better use of available space.
