Which of the following is an application of a 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 item added is the first one to be removed.
Step 2: Learn about breadth-first search (BFS). BFS is an algorithm used to explore or traverse graphs or tree structures level by level.
Step 3: Recognize how BFS uses a queue. In BFS, when a node is discovered, it is added to the queue. The algorithm processes nodes in the order they were added to the queue.
Step 4: Conclude that queues are essential for BFS because they ensure that nodes are processed in the correct order, allowing for a systematic exploration of the graph.
