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

Step 1: Understand what a linear queue is. A linear queue is a simple list where elements are added at the back and removed from the front.
Step 2: Recognize the problem with a linear queue. When you remove elements (dequeue), there are empty spaces at the front that cannot be reused.
Step 3: Learn about a circular queue. A circular queue connects the end of the queue back to the front, forming a circle.
Step 4: See how a circular queue works. When you remove elements, the empty spaces can be filled by adding new elements at the back, reusing the space.
Step 5: Identify the primary advantage. A circular queue uses space more efficiently because it eliminates wasted empty slots.
