Which of the following is a common application of queues?
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 nodes and edges of a graph level by level.
Step 3: Recognize how queues are used in BFS. In BFS, a queue is used to keep track of the nodes that need to be explored next.
Step 4: Realize that when a node is explored, its neighbors are added to the queue, ensuring that nodes are processed in the order they were discovered.
