What data structure is used to implement a breadth-first search (BFS)?

Step 1: Understand what breadth-first search (BFS) is. It is a way to explore nodes in a graph or tree level by level.
Step 2: Know that BFS starts at a specific node and explores all its neighbors before moving on to the next level of nodes.
Step 3: Realize that to keep track of which nodes to explore next, we need a way to store them temporarily.
Step 4: Learn that a queue is the best data structure for this purpose because it follows the first-in, first-out (FIFO) principle.
Step 5: When a node is processed, it is removed from the front of the queue, and any new nodes discovered are added to the back of the queue.
