Which of the following is an application of queues?
Step 1: Understand what a queue is. A queue is a data structure that follows the 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.
Step 3: Recognize how BFS works. It starts at a specific node and explores all its neighbors before moving on to the next level of nodes.
Step 4: Identify the role of queues in BFS. A queue is used to keep track of the nodes that need to be explored next, ensuring they are processed in the order they were added.
Step 5: Conclude that queues are essential for implementing BFS because they maintain the correct order of node exploration.
